Feeding the Void: Co-evolution of the SIDM-seeded Black Hole and the dark halo after core-collapse

Zhichao Carton Zeng, Annika H. G. Peter, Louis E. Strigari +3

While the gravothermal collapse of self-interacting dark matter (SIDM) halos provides a compelling mechanism for seeding supermassive black holes (BHs), the post-collapse macroscop…

An Extended Parametric Model for Self-interacting Dark Matter Halos

Siddhesh Raut, Ethan Nadler, Andrew Benson

We improve upon the parametric model for the evolution of the density profiles of self-interacting dark matter (SIDM) halos introduced in Yang et al. (2024b), by considering the ef…

Bypassed Core Formation in Milky Way-Mass SIDM Halos: Implications for the Local Group Past-Pericenter Scenario

Zhichao Carton Zeng, Odelia V. Hartl, Louis E. Strigari +4

We consider a scenario in which the Milky Way (MW) and M31 have had a previous pericentric passage, and investigate its compatibility with self-interacting dark matter (SIDM). Usin…

A Comparison of Galacticus and COZMIC WDM Subhalo Populations

Jack Lonergan, Andrew Benson, Xiaolong Du

We present a comparative analysis of warm dark matter (WDM) subhalo populations generated by the semi-analytic model {\sc Galacticus} and the COZMIC suite of dark matter-only -b…

A Semi-Analytic model for Effects of Fuzzy Dark Matter Granule Perturbations on Orbital Motion

Yu Zhao, Andrew Benson, Xiaolong Du

In fuzzy dark matter scenarios, the quantum wave nature of ultralight axion-like particles generates stochastic density fluctuations inside dark matter halos. These fluctuations, k…

Calibrating the SIDM Gravothermal Catastrophe with N-body Simulations

Charlie Mace, Shengqi Yang, Zhichao Carton Zeng +3

Self-interacting dark matter (SIDM) theories predict that dark matter halos experience core-collapse in late-stage evolution, a process where the halo's inner region rapidly increa…

Diversity and universality: evolution of dwarf galaxies with self-interacting dark matter

Zhichao Carton Zeng, Annika H. G. Peter, Xiaolong Du +4

Dark matter halos with self-interacting dark matter (SIDM) experience a unique evolutionary phenomenon, in that their central regions eventually collapse to high density through th…

A New Framework for ISM Emission Line Models: Connecting Multi-Scale Simulations Across Cosmological Volumes

Shengqi Yang, Adam Lidz, Andrew Benson +7

The JWST and ALMA have detected emission lines from the ionized interstellar medium (ISM) in some of the first galaxies at . These measurements present an opportunity…

Tidal evolution of cored and cuspy dark matter halos

Xiaolong Du, Andrew Benson, Zhichao Carton Zeng +9

The internal structure and abundance of dark matter halos and subhalos are powerful probes of the nature of dark matter. In order to compare observations with dark matter models, a…

Convergence Tests of Self-Interacting Dark Matter Simulations

Charlie Mace, Zhichao Carton Zeng, Annika H. G. Peter +4

Self-interacting dark matter (SIDM) theory predicts that dark matter halos experience core-collapse, a process where the halo's inner region rapidly increases in density and decrea…

Analytical strong line diagnostics and their redshift evolution

Shengqi Yang, Adam Lidz, Andrew Benson +3

The \textit{JWST} is allowing new measurements of gas-phase metallicities in galaxies between cosmic noon and cosmic dawn. The most robust approach uses luminosity ratios between t…

Till the core collapses: the evolution and properties of self-interacting dark matter subhalos

Zhichao Carton Zeng, Annika H. G. Peter, Xiaolong Du +6

One of the hottest questions in the cosmology of self-interacting dark matter (SIDM) is whether scatterings can induce detectable core-collapse in halos by the present day. Because…
