A Novel Implementation of Self-Interacting Dark Matter in AREPO

Oliver Zier, Xuejian Shen, Vinh Tran +3

Self-interacting dark matter (SIDM) influences halo structure through collisional heat transport and may solve several small-scale puzzles in structure formation. SIDM creates ther…

Role of prompt cusps in driving the core collapse of SIDM halos

Vinh Tran, Daniel Gilman, M. Sten Delos +4

Prompt cusps (PCs) form from the direct collapse of overdensities in the early Universe, reside at the center of every dark matter halo, and have density profiles steeper than $r^{…

Finding the boundary: Using galaxy membership to inform galaxy cluster extent through machine learning

Christine Hao, Stephanie O'Neil, Mark Vogelsberger +3

The spatial extent of the environment's impact on galaxies marks a transitional region between cluster and field galaxies. We present a data-driven method to identify this region i…

Novel density profile for isothermal cores of dark matter halos

Vinh Tran, Xuejian Shen, Mark Vogelsberger +5

We present a novel analytic density profile for halos in self-interacting dark matter (SIDM) models, which accurately captures the isothermal-core configuration, i.e. where both th…

Core collapse in resonant self-interacting dark matter across two decades in halo mass

Vinh Tran, Xuejian Shen, Daniel Gilman +5

Core collapse, a process associated with self-interacting dark matter (SIDM) models, can increase the central density of halos by orders of magnitude with observable consequences f…

Gravothermal Catastrophe in Resonant Self-interacting Dark Matter Models

Vinh Tran, Daniel Gilman, Mark Vogelsberger +3

We investigate a self-interacting dark matter (SIDM) model featuring a velocity-dependent cross section with an order-of-magnitude resonant enhancement of the cross section at $\si…
