The distribution of local star formation activity as a function of galaxy stellar mass, environment and morphology
(2017-12-21)
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 formation rate (SFR) of galaxies: stellar mass, ...
Density profile of dark matter haloes and galaxies in the Horizon-AGN simulation : the impact of AGN feedback
(2017-12-01)
Using a suite of three large cosmological hydrodynamical simulations, Horizon-AGN, Horizon-noAGN (no AGN feedback) and Horizon-DM (no baryons), we investigate how a typical sub-grid model for AGN feedback affects the ...
Cosmic evolution of stellar quenching by AGN feedback : clues from the Horizon-AGN simulation
(2017-11-21)
The observed massive end of the galaxy stellar mass function is steeper than its predicted dark matter halo counterpart in the standard $\Lambda $CDM paradigm. In this paper, we investigate the impact of active galactic ...
Major mergers are not significant drivers of star formation or morphological transformation around the epoch of peak cosmic star formation
(2017-03-01)
We investigate the contribution of major mergers (mass ratios > 1 : 5) to stellar mass growth and morphological transformations around the epoch of peak cosmic star formation (z ∼ 2). We visually classify a complete sample ...
