Velocity dispersion of dark matter deficient ultra-diffuse galaxies: A case for modified gravity
Esha Bhatia, Sayan Chakrabarti, Sovan Chakraborty
The line of sight velocity dispersion of the ultra-diffuse galaxies (UDGs) NGC1052-DF2 and NGC1052-DF4 have been reasonably explained only with the baryonic matter, without requiri…
