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…
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…
Self-Interacting Dark Matter, Core Collapse and the Galaxy-Galaxy Strong Lensing Discrepancy
Isaque Dutra, Priyamvada Natarajan, Daniel Gilman
Gravitational lensing by galaxy clusters has emerged as a powerful tool to probe the standard Cold Dark Matter (CDM) paradigm of structure formation in the Universe. Despite the re…
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…
