The definition of environment and its relation to the quenching of galaxies at z=1-2 in a hierarchical Universe
Matteo Fossati, David J. Wilman, Fabio Fontanot +6
A well calibrated method to describe the environment of galaxies at all redshifts is essential for the study of structure formation. Such a calibration should include well understo…
The stellar accretion origin of stellar population gradients in massive galaxies at large radii
Michaela Hirschmann, Thorsten Naab, Jeremiah P. Ostriker +5
We investigate the evolution of stellar population gradients from to in massive galaxies at large radii () using ten cosmological zoom simulation…
A refined sub-grid model for black hole accretion and AGN feedback in large cosmological simulations
Lisa K. Steinborn, Klaus Dolag, Michaela Hirschmann +2
In large scale cosmological hydrodynamic simulations simplified sub-grid models for gas accretion onto black holes and AGN feedback are commonly used. Such models typically depend…
The influence of the environmental history on quenching star formation in a CDM universe
Michaela Hirschmann, Gabriella De Lucia, Dave Wilman +5
We present a detailed analysis of the influence of the environment and of the environmental history on quenching star formation in central and satellite galaxies in the local Unive…
Variations of the Initial Mass Function in Semi-Analytical models
Fabio Fontanot
Deviations from a universal, MW-like, Stellar Initial Mass Function (IMF) have been reported for distant galaxies, although the physical reason behind the observed variations is st…
The Atlas3D project - XXVI. HI discs in real and simulated fast and slow rotators
Paolo Serra, Ludwig Oser, Davor Krajnovic +24
One quarter of all nearby early-type galaxies (ETGs) outside Virgo host a disc/ring of HI with size from a few to tens of kpc and mass up to ~1e+9 solar masses. Here we investigate…
