Path Measures for Stochastic Galaxy Formation on Layered Halo Graphs
Daneng Yang
Galaxy formation, viewed as an inference problem from incomplete information, is inherently stochastic. Reducing the full simulation state to a coarse-grained set of variables inte…
Flux-ratio anomalies in cusp quasars reveal dark matter beyond CDM
Siyuan Hou, Shucheng Xiang, Yue-Lin Sming Tsai +7
Strongly lensed quasars in cusp configurations provide a uniquely sensitive probe of small-scale dark matter structure. Using the largest microlensing-free flux ratios for 17 quadr…
Dark-Matter-Deficient Galaxies from Collisions: A New Probe of Bursty Feedback and Dark Matter Physics
Yi-Ying Wang, Daneng Yang, Keyu Lu +2
High-velocity collisions between gas-rich ultra-diffuse galaxies present a promising formation channel for dark-matter-deficient galaxies (DMDGs). Using hydrodynamical simulations,…
Self-Interacting Dark Matter with Mass Segregation: A Unified Explanation of Dwarf Cores and Small-Scale Lenses
Daneng Yang, Yi-Zhong Fan, Siyuan Hou +1
In two-component self-interacting dark matter (SIDM) models with inter-species interactions, mass segregation arises naturally from collisional relaxation, enhancing central densit…
Diversifying halo structures in two-component self-interacting dark matter models via mass segregation
Daneng Yang, Yue-Lin Sming Tsai, Yi-Zhong Fan
Self-interacting dark matter (SIDM), through gravothermal evolution driven by elastic self-scatterings, offers a compelling explanation for the observed diversity of inner halo den…
SIDM Concerto: Compilation and Data Release of Self-interacting Dark Matter Zoom-in Simulations
Ethan O. Nadler, Demao Kong, Daneng Yang +1
We present SIDM Concerto: cosmological zoom-in simulations in cold dark matter (CDM) and self-interacting dark matter (SIDM) models based on the Symphony and Milky Way-est sui…
