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…

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…
