Strong-lensing Perturber Signatures in Self-interacting Dark Matter Simulations
Demao Kong, Ethan O. Nadler, Hai-Bo Yu
Motivated by recent detections of low-mass perturbers in strong gravitational lensing systems, we investigate analogs of these objects in the Concerto suite, a set of cosmological…
Novel Challenges in Tracking Self-Interacting Dark Matter Subhalos
Demao Kong, Hai-Bo Yu, Ethan O. Nadler +2
Cosmological N-body simulations are among the primary tools for studying structure formation in the Universe. Analyses of these simulations critically depend on accurately identify…
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…
Probing Signals of Self-Interacting Dark Matter Core Collapse in HI-Rich Galaxies
Demao Kong, Hai-Bo Yu
We analyze rotation curves of five HI-rich galaxies recently discovered with MeerKAT. These galaxies exhibit sharply rising rotation curves, while their baryonic components are not…
