Enhanced Early Galaxy Formation in JWST from Axion Dark Matter?
Simeon Bird, Chia-Feng Chang, Yanou Cui +1
We demonstrate that enhanced early galaxy formation can generically arise in axion-like particle (ALP) dark matter (DM) models with a delayed onset of axion field oscillation. In t…
The impact of baryonic potentials on the gravothermal evolution of self-interacting dark matter haloes
Yi-Ming Zhong, Daneng Yang, Hai-Bo Yu
The presence of a central baryonic potential can have a significant impact on the gravothermal evolution of self-interacting dark matter (SIDM) haloes. We extend a semi-analytical…
A Self-interacting Dark Matter Solution to the Extreme Diversity of Low-mass Halo Properties
Ethan O. Nadler, Daneng Yang, Hai-Bo Yu
The properties of low-mass dark matter (DM) halos appear to be remarkably diverse relative to cold, collisionless DM predictions, even in the presence of baryons. We show that self…
A Parametric Model for Self-Interacting Dark Matter Halos
Daneng Yang, Ethan O. Nadler, Hai-Bo Yu +1
We propose a parametric model for studying self-interacting dark matter (SIDM) halos. The model uses an analytical density profile, calibrated using a controlled N-body SIDM simula…
