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…

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 "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…

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…

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…
