Dark matter fraction derived from the M31 rotation curve
F. Hammer, Y. B. Yang, P. Amram +6
Mass estimates of a spiral galaxy derived from its rotation curve must account for the galaxy's past accretion history. There are several lines of evidence indicating that M31 expe…
The Milky Way accretion history compared to cosmological simulations -- from bulge to dwarf galaxy infall
F. Hammer, Y. J. Jiao, G. A. Mamon +6
Galactic halos are known to grow hierarchically, inside out. This implies a correlation between the infall lookback time of satellites and their binding energy. Cosmological simula…
Gaia EDR3 proper motions, energies, angular momenta of Milky Way dwarf galaxies: a recent infall to the Milky Way halo
Yang Y., Hammer F., Li H. +7
Gaia EDR3 has provided proper motions of Milky Way (MW) dwarf galaxies with an unprecedented accuracy, which allows us to investigate their orbital properties. We found that the to…
Does M31 result from an ancient major merger?
F. Hammer, Y. B. Yang, J. L. Wang +3
The numerous streams in the M31 halo are currently assumed to be due to multiple minor mergers. Here we use the GADGET2 simulation code to test whether M31 could have experienced a…
