RGZ Data Sources Australia Telescope Compact Array The project's scientific team are drawn mostly from Australia, with support from Zooniverse developers and other institutions. They use data taken by the Faint Images of the Radio Sky at Twenty-Centimeters (FIRST) survey which was observed at the Very Large Array between 1993 and 2011. Also used was data from the Australia Telescope Large Area Survey (ATLAS), taken with the Australia Telescope Compact Array (ATCA) in rural New South Wales. The infrared astronomy used was observed by Wide-field Infrared Survey Explorer (WISE) and the Spitzer Space Telescope. RGZ Publications Best-Ever Snapshot of a Black Hole's Jets RGZ has published five scientific studies (May 2018). On the International Centre for Radio Astronomy Research (ICRAR) website, an article from September 2015 named "Volunteer black hole hunters as good as the experts" explains how citizen scientists are as good as professionals at RGZ's tasks. The research team tested trained citizen scientists and ten professional astronomers using a hundred images to help quantify the quality of the data gathered. As the initial results were published, facts and figures from RGZ became available. More than 1.2 million radio images have been looked at, which enabled 60,000 radio sources to be matched to their host galaxies: "A feat that would have taken a single astronomer working 40 hours a week roughly 50 years to complete." Radio Galaxy 3C 83.1B an example of a Wide-angle Tail Radio Galaxy iv) Radio Galaxy Zoo: Cosmological Alignment of Radio Sources (November 2017) Giant Metrewave Radio Telescope In November 2017, a team lead by Omar Contigiani published a paper in Monthly Notices of the Royal Astronomical Society studying the mutual alignment of radio sources. Using data drawn from the Faint Images of the Radio Sky at Twenty Centimeters (FIRST) and TIFR GMRT Sky Survey (TGSS), they investigate the most powerful radio sources, namely the largest elliptical galaxies emitting plasma-filled jets. The abstract begins: "We study the mutual alignment of radio sources within two surveys, FIRST and TGSS. This is done by producing two position angle catalogues containing the preferential directions of respectively 30059 and 11674 extended sources distributed over more than 7000 and 17000 square degrees." The FIRST sample sources were identified by participants in RGZ, while the TGSS sample was the result of an automated process. Marginal evidence of local alignment is found in the FIRST sample, which has a 2\% probability of being by chance. This supports other recent research by scientists using the Giant Metrewave Radio Telescope. The abstract ends: "The TGSS sample is found to be too sparsely populated to manifest a similar signal." Results suggest that there is a relative alignment present at cosmological distances. Gems of the Galaxy Zoos (ZooGems) During the next two years, up to 105 RGZ objects will be observed with the Hubble Space Telescope (HST) as a result of Program 15445, whose P.I. is William Keel. The program's abstract begins: "The classic Galaxy Zoo project and its successors have been rich sources of interesting astrophysics beyond their initial goals. Green Pea starbursts, AGN ionization echoes, dust in backlit spirals, AGN in pseudobulges, have all seen HST followup programs." As a result of NASA 'gap fillers' initiative, it is hoped that significant scientific progress can be made by HST observations of a total of 304 objects, which have been chosen by voters using a Zooniverse custom-made interface. Keel stated: "Each one of them might not be enough for an individual study, but when you put them all together it adds up to an interesting study."
