Gravothermal Collapse: Robust Against Baryonic Feedback
Demao Kong, Hai-Bo Yu
We perform a stress test of gravothermal collapse in self-interacting dark matter (SIDM) halos under baryonic feedback using a semi-analytical oscillating-potential model in contro…
Testing the isothermal Jeans model for self-interacting dark matter halos in the collapse phase
Shubo Li, Moritz S. Fischer, Zixiang Jia +3
We benchmark the semi-analytical isothermal Jeans model against a high-resolution isolated N-body simulation that follows a self-interacting dark matter (SIDM) halo into deep core…
The dark fate of ultra-faint dwarfs: Gravothermal collapse in action
Moritz S. Fischer, Hai-Bo Yu
Ultra-faint dwarf (UFD) galaxies are a promising probe for dark matter (DM) physics as they are the most DM-dominated systems known. The Milky Way (MW) hosts many UFDs for which th…
Strong-lensing Perturber Signatures in Self-interacting Dark Matter Simulations
Demao Kong, Ethan O. Nadler, Hai-Bo Yu
Motivated by recent detections of low-mass perturbers in strong gravitational lensing systems, we investigate analogs of these objects in the Concerto suite, a set of cosmological…
Novel Challenges in Tracking Self-Interacting Dark Matter Subhalos
Demao Kong, Hai-Bo Yu, Ethan O. Nadler +2
Cosmological N-body simulations are among the primary tools for studying structure formation in the Universe. Analyses of these simulations critically depend on accurately identify…
Accurately simulating core-collapse self-interacting dark matter halos
Moritz S. Fischer, Hai-Bo Yu, Klaus Dolag
The properties of satellite halos provide a promising probe for dark matter (DM) physics. Observations have motivated current efforts to explain surprisingly compact DM halos. If D…
