Compaction-Driven Black Hole Growth
Sharon Lapiner, Avishai Dekel, Yohan Dubois
We study the interplay between galaxy evolution and central black-hole (BH) growth using the {NewHorizon} cosmological simulation. BH growth is slow when the dark-matter halo is be…
Evaluating Galaxy Dynamical Masses From Kinematics and Jeans Equilibrium in Simulations
Michael Kretschmer, Avishai Dekel, Jonathan Freundlich +3
We provide prescriptions to evaluate the dynamical mass () of galaxies from kinematic measurements of stars or gas using analytic considerations and the VELA suite of…
The Dekel-Zhao profile: A mass-dependent dark-matter density profile with flexible inner slope and analytic potential, velocity dispersion, and lensing properties
Jonathan Freundlich, Fangzhou Jiang, Avishai Dekel +6
We explore a function with two shape parameters for the dark-matter halo density profile subject to baryonic effects, which is a special case of the general Zhao family of models a…
Origin of Star-Forming Rings around Massive Centres in Massive Galaxies at
Avishai Dekel, Sharon Lapiner, Omri Ginzburg +9
Using analytic modeling and simulations, we address the origin of an abundance of star-forming, clumpy, extended gas rings about massive central bodies in massive galaxies at $z \!…
