Dynamical friction in self-interacting ultralight dark matter

Posted by dbos December 12, 2023Stanford

Kavli Affiliate: Risa H. Wechsler | First 5 Authors: Noah Glennon, Nathan Musoke, Ethan O. Nadler, Chanda Prescod-Weinstein, Risa H. Wechsler | Summary: We explore how dynamical friction in an ultralight dark matter (ULDM) background is affected by dark matter self-interactions. We calculate the force of dynamical friction on a point mass moving through a […]

CSST Strong Lensing Preparation: Forecast the galaxy-galaxy strong lensing population for the China Space Station Telescope

Posted by dbos December 11, 2023Peking

Kavli Affiliate: Hu Zhan | First 5 Authors: Xiaoyue Cao, Ran Li, Nan Li, Rui Li, Yun Chen | Summary: Galaxy-galaxy strong gravitational lens (GGSL) is a powerful probe for the formation and evolution of galaxies and cosmology, while the sample size of GGSLs leads to considerable uncertainties and potential bias. The China Space Station […]
