Introducing galactic structure finder: the multiple stellar kinematic structures of a simulated Milky Way mass galaxy

Aura Obreja, Andrea V. Macciò, Benjamin Moster +4

We present the first results of applying Gaussian Mixture Models in the stellar kinematic space of normalized angular momentum and binding energy on NIHAO high resolution galaxies…

Recoiling Supermassive Black Hole Escape Velocities from Dark Matter Halos

Nick Choksi, Peter Behroozi, Marta Volonteri +4

We simulate recoiling black hole trajectories from to in dark matter halos, quantifying how parameter choices affect escape velocities. These choices include the stren…

NIHAO XVI: The properties and evolution of kinematically selected discs, bulges and stellar haloes

Aura Obreja, Aaron A. Dutton, Andrea V. Macciò +6

We use 25 simulated galaxies from the NIHAO project to define and characterize a variety of kinematic stellar structures: thin and thick discs, large scale single discs, classical…

Probing black hole accretion tracks, scaling relations and radiative efficiencies from stacked X-ray active galactic nuclei

Francesco Shankar, David H. Weinberg, Christopher Marsden +25

The masses of supermassive black holes at the centres of local galaxies appear to be tightly correlated with the mass and velocity dispersions of their galactic hosts. However, the…

Clustering Constraints on the Relative Sizes of Central and Satellite Galaxies

Andrew Hearin, Peter Behroozi, Andrey Kravtsov +1

We empirically constrain how galaxy size relates to halo virial radius using new measurements of the size- and stellar mass-dependent clustering of galaxies in the Sloan Digital Sk…

Local photoionization feedback effects on galaxies

Aura Obreja, Andrea V. Macciò, Benjamin Moster +5

We implement an optically thin approximation for the effects of the local radiation field from stars and hot gas on the gas heating and cooling in the N-body SPH code GASOLINE2. We…
