Weighing Little Red Dots with Transient Events
Vinh Tran, Xuejian Shen, Oliver Zier +3
Recent JWST observations have revealed a large population of compact red sources at , known as Little Red Dots (LRDs), many of which show signatures of accreting massi…
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…
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…
