The inner structure of early-type galaxies in the Illustris simulation
Dandan Xu, Volker Springel, Dominique Sluse +5
Early-type galaxies provide unique tests for the predictions of the cold dark matter cosmology and the baryonic physics assumptions entering models for galaxy formation. In this wo…
The role of mergers and halo spin in shaping galaxy morphology
Vicente Rodriguez-Gomez, Laura V. Sales, Shy Genel +10
Mergers and the spin of the dark matter halo are factors traditionally believed to determine the morphology of galaxies within a CDM cosmology. We study this hypothesis by consi…
The morphology and kinematics of neutral hydrogen in the vicinity of z=0 galaxies with Milky Way masses -- a study with the Illustris simulation
Guinevere Kauffmann, Sanchayeeta Borthakur, Dylan Nelson
We analyze the properties of the circumgalactic gas (CGM) around 120 galaxies with stellar and dark matter halo masses similar to that of the Milky Way. We focus on the morphology…
Simulating galaxy formation with black hole driven thermal and kinetic feedback
Rainer Weinberger, Volker Springel, Lars Hernquist +8
The inefficiency of star formation in massive elliptical galaxies is widely believed to be caused by the interactions of an active galactic nucleus (AGN) with the surrounding gas.…
