The frozen outskirts: a cold Hubble flow and the mass of the Local Group
Danila Makarov, Dmitry Makarov, Lidia Makarova +1
We analyze the velocity field of peripheral members of the Local Group. The Hubble flow at distances from 400 to 1400~kpc, formed by 7 of 11 nearby galaxies, is characterized by an…

Line-of-sight mass estimator and the masses of the Milky Way and Andromeda Galaxy
Danila Makarov, Dmitry Makarov, Kirill Kozyrev +1
The total mass of a galaxy group, such as the Milky Way (MW) and the Andromeda Galaxy (M 31), is typically determined from the kinematics of satellites within their virial zones. B…
