Core Formation in High-z Massive Haloes: Heating by Post Compaction Satellites and Response to AGN Outflows

Avishai Dekel, Jonathan Freundlich, Fangzhou Jiang +6

Observed rotation curves in star-forming galaxies indicate a puzzling dearth of dark matter in extended flat cores within haloes of mass at . T…

A Search for Wandering Black Holes in the Milky Way with Gaia and DECaLS

Jenny E. Greene, Lachlan Lancaster, Yuan-Sen Ting +6

We present a search for "hyper-compact" star clusters in the Milky Way using a combination of Gaia and the Dark Energy Camera Legacy Survey (DECaLS). Such putative clusters, with s…

The tidal evolution of dark matter substructure -- II. The impact of artificial disruption on subhalo mass functions and radial profiles

Sheridan B. Green, Frank C. van den Bosch, Fangzhou Jiang

Several recent studies have indicated that artificial subhalo disruption (the spontaneous, non-physical disintegration of a subhalo) remains prevalent in state-of-the-art dark matt…

Dissipative Dark Matter on FIRE: I. Structural and kinematic properties of dwarf galaxies

Xuejian Shen, Philip F. Hopkins, Lina Necib +3

We present the first set of cosmological baryonic zoom-in simulations of galaxies including dissipative self-interacting dark matter (dSIDM). These simulations utilize the Feedback…

SatGen: a semi-analytical satellite galaxy generator -- I. The model and its application to Local-Group satellite statistics

Fangzhou Jiang, Avishai Dekel, Jonathan Freundlich +5

We present a semi-analytic model of satellite galaxies, SatGen, which can generate large samples of satellite populations for a host halo of desired mass, redshift, and assembly hi…

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…
