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…
Connection between galaxy morphology and dark-matter halo structure II: predicting disk structure from dark-matter halo properties
Jinning Liang, Fangzhou Jiang, Houjun Mo +4
We investigate how galactic disk structures connect to the detailed properties of their host dark-matter halos using the TNG50 simulation. From the hydrodynamic and matched dark-ma…
The "Little Dark Dot": Evidence for Self-interacting Dark Matter in the Strong Lens SDSS J0946+1006?
Shubo Li, Ran Li, Kaihao Wang +13
Previous studies, based on precise modeling of a gravitationally lensing image, have identified what may be an extremely compact, dark perturber in the well-known lensing system SD…
Tidal evolution of cored and cuspy dark matter halos
Xiaolong Du, Andrew Benson, Zhichao Carton Zeng +9
The internal structure and abundance of dark matter halos and subhalos are powerful probes of the nature of dark matter. In order to compare observations with dark matter models, a…
Numerical Challenges in Modeling Gravothermal Collapse in Self-Interacting Dark Matter Halos
Igor Palubski, Oren Slone, Manoj Kaplinghat +2
When dark matter has a large cross section for self scattering, halos can undergo a process known as gravothermal core collapse, where the inner core rapidly increases in density a…
Probabilistic Inference of the Structure and Orbit of Milky Way Satellites with Semi-Analytic Modeling
Dylan Folsom, Oren Slone, Mariangela Lisanti +2
Semi-analytic modeling furnishes an efficient avenue for characterizing the properties of dark matter halos associated with satellites of Milky Way-like systems, as it easily accou…
Till the core collapses: the evolution and properties of self-interacting dark matter subhalos
Zhichao Carton Zeng, Annika H. G. Peter, Xiaolong Du +6
One of the hottest questions in the cosmology of self-interacting dark matter (SIDM) is whether scatterings can induce detectable core-collapse in halos by the present day. Because…
