Self-Interacting Dark Matter: From Particle Physics Theories to Structure Formation Simulations
Martin Rosenlyst, Vinh Tran, Oliver Zier +7
We establish a unified theory-to-simulation framework for self-interacting dark matter (SIDM) that integrates three components: (i) a comprehensive, self-contained treatment of its…
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…
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…
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…
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…
WTP10aaauow: Discovery of a new FU Ori outburst towards the RCW49 star-forming region in NEOWISE data
Vinh Tran, Kishalay De, Lynne Hillenbrand
Large-amplitude accretion outbursts in young stars are expected to play a central role in proto-stellar assembly. Outburst identification historically has taken place using optical…
