Increasing blackhole feedback induced quenching with anisotropic thermal conduction
Rahul Kannan, Mark Vogelsberger, Christoph Pfrommer +5
Feedback from central supermassive blackholes is often invoked to explain the low star formation rates in massive galaxies at the centers of galaxy clusters. However, the detailed…
The Role of Star-Formation and AGN in Dust Heating of z=0.3-2.8 Galaxies - II. Informing IR AGN fraction estimates through simulations
Eric Roebuck, Anna Sajina, Christopher C. Hayward +4
A key question in extragalactic studies is the determination of the relative roles of stars and AGN in powering dusty galaxies at 1-3 where the bulk of star-formation and AG…
Massive Close Pairs Measure Rapid Galaxy Assembly in Mergers at High Redshift
Gregory F. Snyder, Jennifer M. Lotz, Vicente Rodriguez-Gomez +3
We compare mass-selected close pairs at z > 1 with the intrinsic galaxy merger rate in the Illustris Simulations. To do so, we construct three 140 arcmin^2 lightcone catalogs and m…
The information content of stellar halos: Stellar population gradients and accretion histories in early-type Illustris galaxies
B. A. Cook, C. Conroy, A. Pillepich +2
Long dynamical timescales in the outskirts of galaxies preserve the information content of their accretion histories, for example in the form of stellar population gradients. We pr…
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…
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.…
