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…
The Sensitivity of Substructure Lensing to SIDM Core-collapse Model Variation
Charlie Mace, Birendra Dhanasingham, Zhichao Carton Zeng +4
Strong gravitational lensing has emerged as a powerful probe of dark matter substructure, and shows particularly strong promise as a test of self-interacting dark matter (SIDM). Th…
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…
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…
Merian: A Wide-Field Imaging Survey of Dwarf Galaxies at z~0.06-0.10
Shany Danieli, Erin Kado-Fong, Song Huang +32
We present the Merian Survey, an optical imaging survey optimized for studying the physical properties of bright star-forming dwarf galaxies. Merian is carried out with two medium-…
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…
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…
Anisotropic strong lensing as a probe of dark matter self-interactions
Birendra Dhanasingham, Francis-Yan Cyr-Racine, Charlie Mace +2
Galaxy-scale strongly lensed systems have been shown to provide a unique technique for exploring the underlying physics of dark matter at sub-galactic scales. In the past, much att…
The Merian Survey: Design, Construction, and Characterization of a Filter Set Optimized to Find Dwarf Galaxies and Measure their Dark Matter Halo Properties with Weak Lensing
Yifei Luo, Alexie Leauthaud, Jenny Greene +28
The Merian survey is mapping 850 degrees of the Hyper Suprime-Cam Strategic Survey Program (HSC-SSP) wide layer with two medium-band filters on the 4-meter Victor M. Bla…
A quantitative comparison between velocity dependent SIDM cross sections constrained by the gravothermal and isothermal models
Shengqi Yang, Fangzhou Jiang, Andrew Benson +6
One necessary step for probing the nature of self-interacting dark matter (SIDM) particles with astrophysical observations is to pin down any possible velocity dependence in the SI…
