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…
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-…
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…
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…
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…
