Astronomers solve the 60-year mystery of quasars, the most powerful objects in the universe sheffielduni RoyalAstroSoc
Thumbnail images of the 19 type 2 quasar objects classified as pre-coalescence systems. In each case north is to the top and east to the left, and the bar in the bottom left-hand corner indicates a distance of 20 kpc at the redshift of the source. The type 2 quasar object is generally situated close to the centre of the image, but in cases where there might be ambiguity due to close companion galaxies, the type 2 quasar is identified by line segments.
Note that the distinction between pre- and post-coalescence is not always clear-cut. For example, J1300+5454 is situated in a galaxy group in which multiple galaxy interactions are taking place. It has been classified as a post-coalescence system using the Zooniverse interface, presumably on the basis that it shows tidal features at modest radial distances , but no nearby companion or secondary nucleus is detected.
As well as the detailed morphology, the classifiers were asked to indicate which of the following labels best described the overall morphological type of the galaxy: spiral/disc ; elliptical ; lenticular ; and merger . As for the detailed classifications, the final overall morphological type was determined based on a simple majority of the Zooniverse votes. Objects for which no majority was obtained for any particular type were classified as uncertain .
