Semi-analytic Inference of Satellite Densities in the Cold Dark Matter Model Part II. Implications for Dark Matter Indirect Detection Constraints
Kailash Raman, Dylan Folsom, Manoj Kaplinghat +2
The paper updates the astrophysical J‑factors for Milky Way dwarf spheroidal galaxies using a calibrated semi‑analytic satellite model and new stellar kinematic data, and shows how…
Semi-analytic Inference of Satellite Densities in the Cold Dark Matter Model Part I. Comparison to Ultra-faint Dwarf Kinematics
Kailash Raman, Dylan Folsom, Manoj Kaplinghat +2
The paper uses a semi‑analytic model of Milky Way satellite galaxies to predict their dark‑matter density profiles and compares these predictions to measurements of stellar velocit…
Mergers Matter: Gravothermal Collapse in Dwarf Halos with Self-Interacting Dark Matter
Maya Silverman, Abdelaziz Hussein, Arpit Arora +8
Self-Interacting Dark Matter (SIDM) models with large cross sections at relative velocities below can be tested with dwarf galaxy observations. We ana…
Semi-Analytic Modeling of Dark Matter Subhalo Encounters with Thin Stellar Streams: Statistical Predictions for GD-1-like Streams in CDM
Duncan K. Adams, Aditya Parikh, Oren Slone +3
Stellar streams from disrupted globular clusters are dynamically cold structures that are sensitive to perturbations from dark matter subhalos, allowing them in principle to trace…
Survival of the most compact: the life and death of satellite halos in self-interacting dark matter
David Klemmer, Moritz S. Fischer, Kimberly K. Boddy +2
Self-interacting dark matter (SIDM) models feature short-range interactions between dark matter (DM) particles that lead to larger diversity in the inner parts of galactic rotation…
Astrophysical Tests of Dark Matter Self-Interactions
Susmita Adhikari, Arka Banerjee, Kimberly K. Boddy +11
Self-interacting dark matter (SIDM) arises generically in scenarios for physics beyond the Standard Model that have dark sectors with light mediators or strong dynamics. The self-i…
