galaxy zoo data

Look at telescope images of distant galaxies. Over 16 million galaxy classifications. (2010b). 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. Simmons et al. 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. The images come from single-epoch observations by SDSS, but use the same decision tree and interface as the data in Tables 4-7. 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. Galaxy Zoo Results! Data is derived from the Zoo 1 and Zoo 2 periods (August 2007–April 2010), and is described in detail by Keel et al. THIS SITE IS NOW ARCHIVED; go here for the 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. This webpage allows anyone to download the resulting GZ classifications of nearly 900,000 galaxies in the project. About Galaxy Zoo To understand how galaxies formed we need your help to classify them according to their shapes. This site is still alive for nostalgia's sake, but your classifications will not form part of the public data release. These tables are also accessible via CasJobs. Zoo Media. CANDELS: The new data in Galaxy Zoo This post is the second of a series introducing the new Galaxy Zoo.The first is here, and you should come back in the next few days for more information about our fabulous new site. 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. 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 … (2016): we strongly advise the use of the Hart et al. You decide which simulation wins in a series of tournament-style competitions. All of the data which is currently publicly available from any phase of Galaxy Zoo is available on our Data Archive site. population. we need you now more than ever!. Galaxy Zoo 2 (GZ2) was the successor project to Galaxy Zoo. that work. Table 6 contains classifications of 3,927 galaxies from the COSMOS survey. The GZ2 catalog is also accessible via CasJobs in Data Release 10. Debiased morphologies for this sample are slightly more uncertain than Table 5, since the data reduction requires a redshift to adjust the morphology for classification bias. Information on more than 300,000 galaxies. These tables provide the GZ2 classifications for nearly 300,000 galaxies in the SDSS. Galaxy Zoo 2 - which asks for more detailed classifications of roughly 250,000 of the brightest galaxies in our sample is now live. 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. This table gives a series of measures of the classification confidence. Catalogues of the galaxy properties, along with multi-wavelength coverage from radio through ultraviolet, are available here. 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. 2008, MNRAS, 389, 1179 and the data release is described in Lintott et al. Table 6 gives classifications of the 42,462 galaxies in the main sample with photometric redshifts only. The project description and data reduction is in Willett et al. The first papers and follow-up observations are complete, and you can follow our progress on the BLOG and FORUM. 2013) publications if using this data. In the end, more than 50 million classifications were received by the project during its first year, contributed by more than 150,000 people. For the latest Galaxy Zoo press release (including team contact details for members of the press) please see the main Galaxy Zoo … The Zooniverse is the world’s largest and most popular platform for people-powered research. ellipticals are red, It is a Zooniverse tradition to recognize their contributions as co-authors, and we gladly support that tradition. © Galaxy Zoo 2007 and Sloan Digital Sky Survey. If you're quick, you may even be the first person to see the galaxies you're asked to classify. GZ2 extends the original Galaxy Zoo classifications for a subsample of the brightest and largest galaxies in the Legacy release, measuring more detailed morphological features. described in Masters This was started in July 2007 and retired i… "They realized that we'd found a great way to sort a lot of data fast." The full data reduction pipeline and analysis codes for GZH are available as an open-source Github repository. Please cite this paper if using any data from Galaxy Zoo: CANDELS. (PASP, 2013, 125, 923). Zooniverse now offers several citizen science projects, including three more using NASA data. 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. (2011) for a description of the project and scientific results. The rows/columns are transposed from the version in the printed article (which was done only to illustrate form and content). (2010), and Galaxy Zoo 2 - which asks for more detailed classifications of roughly 250,000 of the brightest galaxies in … See this page for full details and data for the separate Galaxy Zoo: Mergers project. 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. 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. (2010) and latest Galaxy Zoo project. Table 5 contains classifications of 3,927 galaxies from the COSMOS survey. This post is also part of Citizen Science September at the Zooniverse. November 20, 2014 — 0 Comments. This table provides pre-matched sets of metadata for the Galaxy Zoo 2 samples taken from DR7. 2008 . The properties To see the final data release visit the data page here. Images for GZH were taken from the Advanced Camera for Surveys (ACS) aboard Hubble, including data from multiple Legacy surveys. Such a database will have substantial legacy value for the international astronomy community. 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. Coadded images are made from combining between 47–55 individual exposures, resulting in better detection of fainter features and improved seeing. This is what But Table 6 - Main sample, photometric redshifts. More than 6000 users contributed to the project by running and reviewing simulations or by participating in Merger Wars. Value-added GZ data includes the morphologies of the merging galaxies as well as the relative stage of the merger. The catalog contains a total of 1990 galaxy pairs. 2011, 410, 166. Table 7 contains classifications of 6,144 galaxies from the GOODS-N and GOODS-S surveys. 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… This includes coordinates, photometry, size, and redshifts (where present). Table 10 - Morphological classifications for images with simulated AGN. As we approach the 8 th anniversary of the Galaxy Zoo project, it is a great opportunity to look back at one of the most fascinating discoveries of citizen science in Galaxy Zoo – the “Green Pea” galaxies. "Green peas" are compact galaxies with extremely high star-formation rates. In his spare time, he runs probably more than is healthy. These colour composite images had the red and blue channels swapped from default settings, and tested the effects of colour perception on morphological consistency. With your help, we collected millions of classifications, and have done more and better science faster than we ever believed possible. Table 9 gives classifications of the second set of 19,761 galaxies classified in the coadded (runs 106 and 206) Stripe 82 images. 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. The Galaxy Zoo scientists have created a tool called Navigator that allows Zooites (Galaxy Zoo contributors) to form groups and analyze galaxies together. Spectroscopic classification of galaxy based on emission lines ratios in the BPT diagram. This is the primary GZ2 data release, containing the largest number of galaxies and the most reliable morphologies. This table gives classifications of galaxies which have spectra included in SDSS Data Release 7. This includes galactic bars, spiral arm and pitch angle, bulges, edge-on galaxies, relative ellipticities, and many others. The project is further described in Lingard et al. Table 8 gives classifications of the first set of 19,765 galaxies classified in the coadded (runs 106 and 206) Stripe 82 images. interesting (2016) table, as this debiases the GZ2 quetion tree most consistently. 2013. (2009). so this sample of red This includes (where available) redshifts, magnitudes, angular sizes, automatically-measured morphological parameters, and additional flags from the parent surveys. This sample of merging galaxies is assembled from SDSS Galaxy Zoo 1 data. This table gives the results from the bias study that introduced monochrome images. spirals is an "Red Please cite the DLSG (Kaviraj et al. gives the red and blue The images come from co-added observations over dozens of epochs by SDSS, as compared to the shallower single-epoch images in Table 8. These morphologies are related to probabilities for each category; a high number (close to 1) indicates that many users identified this morphology category for the galaxy with a high level of confidence. Most spiral The various overlapping galaxy pair types are illustrated in Figures 2a and 2b from Keel et al. et al. Anyone making use of the data should cite at least one of these papers in any resulting publications. red spirals are 2013) and Galaxy Zoo 2 (Willett 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. Zooniverse is a citizen science web portal owned and operated by the Citizen Science Alliance.It is home to some of the internet's largest, most popular and most successful citizen science projects. Raw and weighted classifications for the full Galaxy Zoo: CANDELS sample. 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. colour, while most Data Collection Closed. The data 2012; Shabala et al. Classifications and depth-corrections for 10,648 galaxies in GZC that had imaging at multiple co-added epochs. Table 7 - Morphological classifications for galaxies from 2-epoch GOODS imaging. Table 8 - Stripe 82, coadded-depth (set 1). Table 8 contains classifications of 21,522 galaxies located in SDSS Stripe 82. These images were faded to very low colour saturation before classification, and tested the effects of colour gradients on morphological consistency. This proof-of-concept project uses members of the public to identify supernova candidates from the latest generation of wide-field imaging transient surveys. Thank you again to all of our volunteers. Minneapolis — St. Paul: More than 83,000 volunteer citizen scientists. Table 8 - Morphological classifications for single-epoch SDSS images of galaxies in Stripe 82. This table gives the fraction of votes in each of the six categories, combining results from the main and bias studies. Citizen Science. 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. colour. Table 9 - Morphological classifications for co-added SDSS images of galaxies in Stripe 82. (2009). Authors. The primary goal of Galaxy Zoo is to construct a database of detailed shape information for almost all the galaxies the Hubble Space Telescope has ever seen. We Need Us. The closest excerpt I can find (p 142) is: "Like a computer, Galaxy Zoo can find patterns in large data sets, data sets far beyond the comprehension of any single individual. Citizen Science, Galaxy Zoo, Projects. (2017) (available both from arXiv or the MNRAS journal) describes the project and data release. This section contains data from the Galaxy Zoo survey for overlapping galaxy pairs, useful for studies of dust absorption. Table 6 - Morphological classifications for recoloured galaxies. optically red in (2020). Shown here is a diagram of the classification scheme and decision tree used in GZ: Hubble. et The Galaxy Zoo UI. Download here: schawinski_GZ_2010_catalogue.fits.gz. As you answer, we lead you down a decision tree where the questions depend on how you’ve previously responded. The Galaxy Zoo: Mergers project is grateful for the contributions of all of our Citizen Science volunteers. This set of images had no adjustments made to its background, which resulted in coloured background noise for some galaxies. (2014) used GZ2 and preliminary GZ: Hubble data to study the evolution of the bar fraction in galaxies over cosmic timescales.
