Merger Wars. This table gives the fraction of votes in each of the six categories, combining results from the main and bias studies. 2012; Shabala et al. See this page for full details and data for the separate Galaxy Zoo: Mergers project. The Galaxy Zoo team has run many projects that study the large-scale properties of galaxies, such as their shape, characteristics, and patterns in their behavior. Properties of the initial sample are described in Cardamone et al. This site is still alive for nostalgia's sake, but your classifications will not form part of the public data release. 2013, MNRAS, 435, 2835 — please cite this paper if making any use of the GZ2 data. Data Collection Closed. Over 16 million galaxy classifications. Table 8 - Stripe 82, coadded-depth (set 1). When using this sample, please cite Schawinski et al. Value-added GZ data includes the morphologies of the merging galaxies as well as the relative stage of the merger. 2011, 410, 166. These images are shallow exposures created from 2-epoch imaging, as contrasted with the deeper 5-epoch imaging of galaxies from GOODS in Table 4. If you're quick, you may even be the first person to see the galaxies you're asked to classify. optically red in About Galaxy Zoo To understand how galaxies formed we need your help to classify them according to their shapes. Two debiased Galaxy Zoo tables are provided, described in Willett et al. These represent the morphology (or shape) of the galaxy in 37 different categories as identified by crowdsourced volunteer classifications as part of the Galaxy Zoo 2 project. identified spiral structure which are Zooniverse now offers several citizen science projects, including three more using NASA data. Galaxy Zoo 2: detailed morphological classifications for 304,122 galaxies from the Sloan Digital Sky Survey, now accepted for publication in the Monthly Notices of the Royal Astronomical Society, is the result of a lot of hard work by Kyle Willett and friends. This proof-of-concept project uses members of the public to identify supernova candidates from the latest generation of wide-field imaging transient surveys. Table 9 contains classifications of 30,339 galaxies located in SDSS Stripe 82. Table 10 - Morphological classifications for images with simulated AGN. The first papers and follow-up observations are complete, and you can follow our progress on the BLOG and FORUM. These tables are also accessible via CasJobs. 2013) and Galaxy Zoo 2 (Willett et al. Anyone making use of the data should cite at least one of these papers in any resulting publications. colour, while most We Need Us. With so many galaxies, it had been assumed that it would take years for visitors to the site to work through them all, but within 24 hours of launch, the website was receiving almost 70,000 classifications an hour. (2014) used GZ2 and preliminary GZ: Hubble data to study the evolution of the bar fraction in galaxies over cosmic timescales. October 13, 2014. (PASP, 2013, 125, 923). Volunteers on the forum first noted these galaxies due to their peculiar bright green color and small size. Data below is from Table 4 in Cardamone et al. A Galaxy Zoo Timeline. The Zooniverse is the world’s largest and most popular platform for people-powered research. ellipticals are red, Galaxy Builder made use of citizen science to create disc-bulge-bar-spiral photometric models of 198 spiral galaxies, selected using GZ2 and the NASA-Sloan Atlas. Citizen Science. Please cite this paper if using any data from the project. Download here: schawinski_GZ_2010_catalogue.fits.gz. Galaxy Zoo Results! Look at telescope images of distant galaxies. It all started back in July 2007, with a data set made up of a million galaxies imaged by the Sloan Digital Sky Survey, who still provide some of the images in the site today. You decide which simulation wins in a series of tournament-style competitions. New in SDSS Data Release 10 are more detailed classifications of internal structure of the brightest 25% of the Main Galaxy Sample from Galaxy Zoo 2 . "Red The data Minneapolis — St. Paul: More than 83,000 volunteer citizen scientists. Galaxy Zoo is a website that asks members of the public to classify galaxies for us. SDSS model magnitudes. Their name comes from their appearance in colour SDSS images, which is due to strong [OIII] λ5007 emission that appears in the r-band filter for large numbers of low-redshift (0.112 < z < 0.360) galaxies. (2017) (available both from arXiv or the MNRAS journal) describes the project and data release. This is the primary GZ2 data release, containing the largest number of galaxies and the most reliable morphologies. Most spiral The table numbers below are the same as their order in the paper. After Galaxy Zoo kicked off, scientists began approaching Lintott at conferences asking for help. The properties Table 7 - Morphological classifications for galaxies from 2-epoch GOODS imaging. (2010) and Lintott et al. There is a similar file of candidate pairs which were rejected for the final list because of evidence for interaction, other geometric reasons, or for having redshifts the wrong way around for dust backlighting. A1 and A2 in Masters Please cite the DLSG (Kaviraj et al. interesting This paper presents the first results from a new citizen science project: Galaxy Zoo Supernovae. Galaxy Zoo 1 data are described in Lintott et al. In short, we hope to find out everything there is to know about the appearance of galaxies! http://astronomy.ua.edu/keel/observe/PDFcharts, http://gz2hart.s3.amazonaws.com/gz2_hart16.csv.gz, http://gz2hart.s3.amazonaws.com/gz2_hart16.fits.gz, http://gz2hart.s3.amazonaws.com/gz2_hart16.vot.gz, Low mass sample (10.0≤log(Mstar)<10.34; N=789), Intermediate mass sample (10.34≤log(Mstar)<10.64; N=801), High mass sample (log(Mstar)≥10.64; N=790), Cosmic Assembly Near-infrared Deep Extragalactic Legacy Survey (CANDELS). This table includes raw and weighted morphological classifications for all tasks in the GZC classification tree for each of the 49,555 unique sources in the sample. Such a database will have substantial legacy value for the international astronomy community. Melvin et al. The catalog contains a total of 1990 galaxy pairs. To see the final data release visit the data page here. Julie Freeman – ‘We Need Us’ presentation. These colour composite images had the red and blue channels swapped from default settings, and tested the effects of colour perception on morphological consistency. Table 7 contains classifications of 6,144 galaxies from the GOODS-N and GOODS-S surveys. We show you a galaxy, and we ask simple questions about what you can see, like – is the galaxy smooth, or featured? History of Galaxy Zoo The launch of this new version of Galaxy Zoo, the 4th, comes just a few weeks after the site’s 5th birthday. This site is still alive for nostalgia's sake, but your classifications will not form part of the public data release. Table 5 contains classifications of 3,927 galaxies from the COSMOS survey. The Galaxy Zoo: Mergers project is grateful for the contributions of all of our Citizen Science volunteers. This table gives the results from the bias study that introduced mirrored images. The various overlapping galaxy pair types are illustrated in Figures 2a and 2b from Keel et al. This table gives classifications of galaxies included in the Galaxy Zoo sample which did not have spectra available in SDSS Data Release 7. Coadded images are made from combining between 47–55 individual exposures, resulting in better detection of fainter features and improved seeing. Citizen Science, Galaxy Zoo, Projects. Classifications and depth-corrections for 10,648 galaxies in GZC that had imaging at multiple co-added epochs. "Green peas" are compact galaxies with extremely high star-formation rates. Table 9 - Morphological classifications for co-added SDSS images of galaxies in Stripe 82. The full set of results can be downloaded below. we need you now more than ever!. In the original Galaxy Zoo project, volunteers classified images of Sloan Digital Sky Survey galaxies as belonging to one of six categories - elliptical, clockwise spiral, anticlockwise spiral, edge-on , star/don't know, or merger. Table 5 gives classifications of the 243,500 galaxies in the main sample with spectroscopic redshifts. The project description and data reduction is in Willett et al. Simmons et al. (2010), and Raw and weighted classifications for the full Galaxy Zoo: CANDELS sample. He lead the data reduction and catalog creation from Galaxy Zoo 2 classifications, has worked on building new tools to enable independent research by citizen science volunteers and now leads efforts to include new data sets in Galaxy Zoo. (2011) for a description of the project and scientific results. It is not possible to estimate the bias in this sample without accurate redshifts, and so only the fraction of the vote in each of the six categories is given. described in Masters We present this method as a powerful new approach to data exploration by providing a detailed understanding of the morphology and relationships of Radio Galaxy Zoo (RGZ) dataset image features which can be applied to new radio survey data. Galaxy Zoo: CANDELS classified the morphology of galaxies in images from the Cosmic Assembly Near-infrared Deep Extragalactic Legacy Survey (CANDELS). (2009). It is a homogenous sample of galaxies (0.005 < z < 0.1) with spectroscopy for at least one of two merging galaxies in the pair. Table 4 - Morphological classifications for galaxies in main HST sample, Table 4 contains classifications of 113,705 galaxies aggregated from four, Table 5 - Morphological classifications for faded galaxies. that work. So go here to get classifying. Classify the morphologies of distant galaxies in our Universe 2013. 2013) publications if using this data. The project is further described in Lingard et al. Just click the "Galaxy Zoo" link under "Imaging Summary" in the left-hand sidebar (example here). The current claim is based on a sample of just 1660 galaxies from the SDSS survey, but a much larger sample is required to assess the significance of the effect which is where Galaxy Zoo comes in. With your help, we collected millions of classifications, and have done more and better science faster than we ever believed possible. This post is also part of Citizen Science September at the Zooniverse. Early Galaxy Zoo 2 classifications were used to identify a sample of 362 spheroidal galaxies with prominent dust lanes (DLSGs), ranging from redshifts of z=0.01 to 0.07. September 11, 2015 — 0 Comments. The full reduction and analysis of GZ: Hubble was published in Willett et al. galaxies are blue in It is a volume-limited sample of galaxies (0.02 < z < 0.05, Mz < –19.5 AB) with emission line classifications, stellar masses, velocity dispersions and GZ1 morphological classifications. Their names are: This sample is presented in the Galaxy Zoo 1 paper on AGN host galaxies (Schawinski et al., 2010, ApJ, 711, 284). The organization grew from the original Galaxy Zoo project and now hosts dozens of projects which allow volunteers to participate in crowdsourced scientific research. (2010b). This set of images applied a modest colour desaturation to de-emphasise background noise in the coadded data. spiral samples from Justin is the project manager for Unearthing Michigan Ecological Data, a project that uses the Zooniverse crowdsourcing platform to identify data within a large collection of papers written by… With data on more than 300,000 nearby galaxies, the Galaxy Zoo 2 catalog is 10 times larger than any previous catalog of its kind. spirals is an The Clump Scout project is a bit different because our focus is on a much smaller target. Below are PDF files containing a single page for each galaxy pair, plus finding charts, more detailed photometry and identifications, and in some cases more precise redshifts. November 20, 2014 — 0 Comments. Galaxy Zoo has been an attempt to get citizen science to classify all the galaxies present in various data sets, such as the Sloan and Hubble surveys, as elliptical, spiral, etc. The original Galaxy Zoo consisted of a data set made up of about 900,000 galaxies imaged by the Sloan Digital Sky Survey. This includes galactic bars, spiral arm and pitch angle, bulges, edge-on galaxies, relative ellipticities, and many others. It was replaced by Galaxy Zoo 2, Galaxy Zoo: Hubble, and Galaxy Zoo: CANDELS. Galaxy Zoo 2 - which asks for more detailed classifications of roughly 250,000 of the brightest galaxies in our sample is now live. This table provides pre-matched sets of metadata for the Galaxy Zoo 2 samples taken from DR7. Galaxy Zoo Mergers is now in an archive status. These tables provide the GZ2 classifications for nearly 300,000 galaxies in the SDSS. This set of images had no adjustments made to its background, which resulted in coloured background noise for some galaxies. CANDELS images were taken with both the ACS and WFC3 cameras on the Hubble Space Telescope, focusing on rest-frame optical wavelengths of galaxies at redshifts of 1 < z < 3. colour. Authors. The rows/columns are transposed from the version in the printed article (which was done only to illustrate form and content). Data is derived from the Zoo 1 and Zoo 2 periods (August 2007–April 2010), and is described in detail by Keel et al. In his spare time, he runs probably more than is healthy. Coadded images are made from combining between 47–55 individual exposures, resulting in better detection of fainter features and improved seeing. The Story So Far Galaxy Zoo is now arguably the world’s best-known online citizen science project, and is certainly the one with the largest number of … The magnitude limit for Stripe 82 classifications (r<17.7) is slightly deeper than the main samples. The catalog contains a total of 1990 galaxy pairs. (2017) (available both from arXiv or the MNRAS journal). (2016) table, as this debiases the GZ2 quetion tree most consistently. Table 10 contains classifications of 2,961 HST images that contain both a real galaxy and a simulated nuclear point source of varying intensity and colour. Galaxy Zoo 1: data release of morphological classifications for nearly 900 000 galaxies ... Riccardo Giovanelli, Kevin Schawinski, Galaxy Zoo and ALFALFA: atomic gas and the regulation of star formation in barred disc galaxies, Monthly Notices of the Royal Astronomical Society, 10.1111/j.1365-2966.2012.21377.x, 424, 3, (2180-2192), (2012). For science cases, we encourage users to instead use the latest measurements from the latest data release. But This section contains data from the Galaxy Zoo survey for overlapping galaxy pairs, useful for studies of dust absorption. The GZ2 catalog is also accessible via CasJobs in Data Release 10. For the latest Galaxy Zoo press release (including team contact details for members of the press) please see the main Galaxy Zoo … (2009). compared to a match 2008, MNRAS, 389, 1179 and the data release is described in Lintott et al. population. This includes (where available) redshifts, magnitudes, angular sizes, automatically-measured morphological parameters, and additional flags from the parent surveys. Please cite this paper if using any data from Galaxy Zoo: CANDELS. latest Galaxy Zoo project. These tables contain useful metadata matched to the morphological data in Tables 4–9. The table names in CasJobs are: For any object in SDSS DR10, you can access its Galaxy Zoo or Galaxy Zoo 2 classifications (if present) by using the "Explore" tool. ENGLISH| POLSKI. (2016): we strongly advise the use of the Hart et al. 2012; Kaviraj et al. Images for GZH were taken from the Advanced Camera for Surveys (ACS) aboard Hubble, including data from multiple Legacy surveys. This table gives a series of measures of the classification confidence. (2013) and Hart et al. Within the Navigator tool, you can create many different graphs from the data your group analyzes. In the end, more than 50 million classifications were received by the project during its first year, contributed by more than 150,000 people. The Galaxy Zoo scientists have created a tool called Navigator that allows Zooites (Galaxy Zoo contributors) to form groups and analyze galaxies together.
