Identifying the progenitors of present-day early-type galaxies in observational surveys: correcting `progenitor bias' using the Horizon-AGN simulation
G. Martin, S. Kaviraj, J. E. G. Devriendt +3
As endpoints of the hierarchical mass-assembly process, the stellar populations of local early-type galaxies encode the assembly history of galaxies over cosmic time. We use Horizo…
The distribution of local star formation activity as a function of galaxy stellar mass, environment and morphology
E. K. Lofthouse, S. Kaviraj, D. J. B. Smith +1
We present a detailed inventory of star formation in the local Universe, dissecting the cosmic star formation budget as a function of key variables that influence the star formatio…
The limited role of galaxy mergers in driving stellar mass growth over cosmic time
G. Martin, S. Kaviraj, J. E. G. Devriendt +3
A key unresolved question is the role that galaxy mergers play in driving stellar mass growth over cosmic time. Recent observational work hints at the possibility that the overall…
Large Synoptic Survey Telescope Galaxies Science Roadmap
Brant E. Robertson, Manda Banerji, Michael C. Cooper +47
The Large Synoptic Survey Telescope (LSST) will enable revolutionary studies of galaxies, dark matter, and black holes over cosmic time. The LSST Galaxies Science Collaboration has…
Galaxy Zoo: major galaxy mergers are not a significant quenching pathway
Anna K. Weigel, Kevin Schawinski, Neven Caplar +9
We use stellar mass functions to study the properties and the significance of quenching through major galaxy mergers. In addition to SDSS DR7 and Galaxy Zoo 1 data, we use samples…
This is not the feedback you have been looking for: nearby optical AGN rarely drive kpc-scale cold-gas outflows
Borislav Nedelchev, Marc Sarzi, Sugata Kaviraj
We study the interstellar Na I (Na D) absorption-line doublet in a nearly-complete sample of 9900 nearby Seyfert 2 galaxies, in order to quantify the significa…
