Properties of Resonantly Produced Sterile Neutrino Dark Matter Subhalos
Shunsaku Horiuchi, Brandon Bozek, Kevork N. Abazajian +4
The anomalous 3.55 keV X-ray line recently detected towards a number of massive dark matter objects may be interpreted as the radiative decays of 7.1 keV mass sterile neutrino dark…
The no-spin zone: rotation vs dispersion support in observed and simulated dwarf galaxies
Coral Wheeler, Andrew B. Pace, James S. Bullock +6
We perform a systematic Bayesian analysis of rotation vs. dispersion support () in dwarf galaxies throughout the Local Volume (LV) over a stellar mass range $…
The Impact of Baryonic Physics on the Structure of Dark Matter Halos: the View from the FIRE Cosmological Simulations
T. K. Chan, D. Kereš, J. Oñorbe +4
We study the distribution of cold dark matter (CDM) in cosmological simulations from the FIRE (Feedback In Realistic Environments) project, for g…
Sweating the small stuff: simulating dwarf galaxies, ultra-faint dwarf galaxies, and their own tiny satellites
Coral Wheeler, Jose Onorbe, James S. Bullock +5
We present FIRE/Gizmo hydrodynamic zoom-in simulations of isolated dark matter halos, two each at the mass of classical dwarf galaxies () and…
Effects of Coupled Dark Energy on the Milky Way and its Satellites
Camilla Penzo, Andrea V. Macciò, Marco Baldi +2
We present the first numerical simulations in coupled dark energy cosmologies with high enough resolution to investigate the effects of the coupling on galactic and sub-galactic sc…
Lagrangian Volume Deformations around Simulated Galaxies
S. Robles, R. Domínguez-Tenreiro, J. Oñorbe +1
We present a detailed analysis of the local evolution of 206 Lagrangian Volumes (LVs) selected at high redshift around galaxy seeds, identified in a large-volume cold dark matt…
