Exploring velocity dispersion anisotropy in a dark matter dominated ultra-diffuse galaxy with modified gravity models
Esha Bhatia, Sayan Chakrabarti, Sovan Chakraborty
The kinematics of the ultra-diffuse galaxy (UDG) NGC1052-DF44 is primarily influenced by the presence of dark matter (DM). In this paper, we conduct a contrasting kinematic study o…
