The impact of mechanical AGN feedback on the formation of massive early-type galaxies
Ena Choi, Jeremiah P. Ostriker, Thorsten Naab +2
We employ cosmological hydrodynamical simulations to investigate the effects of AGN feedback on the formation of massive galaxies with present-day stellar masses of $M_{stel} = 8.8…
SPHGal: Smoothed Particle Hydrodynamics with improved accuracy for Galaxy simulations
Chia-Yu Hu, Thorsten Naab, Stefanie Walch +2
We present the smoothed-particle hydrodynamics implementation SPHGal, which combines some recently proposed improvements in GADGET. This includes a pressure-entropy formulation wit…
Galaxy size trends as a consequence of cosmology
M. J. Stringer, F. Shankar, G. S. Novak +3
We show that recently documented trends in galaxy sizes with mass and redshift can be understood in terms of the influence of underlying cosmic evolution; a holistic view which is…
The Dynamics of Galaxy Pairs in a Cosmological Setting
Jorge Moreno, Asa F. L. Bluck, Sara L. Ellison +3
We use the Millennium Simulation, and an abundance-matching framework, to investigate the dynamical behaviour of galaxy pairs embedded in a cosmological context. Our main galaxy-pa…
Consequences of Mechanical and Radiative Feedback from Black Holes in Disc Galaxy Mergers
Ena Choi, Thorsten Naab, Jeremiah P. Ostriker +2
We study the effect of AGN mechanical and radiation feedback on the formation of bulge dominated galaxies via mergers of disc galaxies. The merging galaxies have mass-ratios of 1:1…
Numerical hydrodynamic simulations based on semi-analytic galaxy merger trees: method and Milky-Way like galaxies
Benjamin P. Moster, Andrea V. Macciò, Rachel S. Somerville
We present a new approach to study galaxy evolution in a cosmological context. We combine cosmological merger trees and semi-analytic models of galaxy formation to provide the init…
