Journal ArticleDOI
A search for the most massive galaxies – III. Global and central structure
TL;DR: In this paper, the authors used the Advanced Camera for Surveys on board the Hubble Space Telescope to obtain high resolution i-band images of the centers of 23 single galaxies, which were selected because they have SDSS velocity dispersions larger than 350 km s 1.

TL;DR: In this paper, a study of quasar selection using the supernova fields of the DES images is presented, where the completeness and efficiency of selection methods involving color, probabilistic modeling, variability, and combinations of color/probabilistic modelling with variability are evaluated.

TL;DR: Amara et al. as discussed by the authors measured the redshift evolution of galaxy bias for a magnitude limited galaxy sample by combining the galaxy density maps and weak lensing shear maps for a ˜116 deg2 area of the Dark Energy Survey (DES) Science Verification (SV) data.

TL;DR: The most distant superluminous supernova (SLSN) spectroscopically confirmed to date is DES15E2mlf as discussed by the authors, which has a stellar mass of 3.5+3.4 × 109 M, which is more massive than the typical SLSN-I host galaxy.
Journal ArticleDOI
Galaxy Zoo: Multi-Mergers and the Millennium Simulation
Daniel Darg,Sugata Kaviraj,Chris Lintott,Kevin Schawinski,Joseph Silk,Stuart Lynn,Steven P. Bamford,Robert C. Nichol +7 more
TL;DR: In this article, the authors present a catalogue of 39 multiple-mergers found using the mergers catalogue of the Galaxy Zoo project for $z < 0.1$ and compare them to corresponding semi-analytical galaxies from the Millennium Simulation.
