Impact of merger histories on the timing argument estimate of the Local Group mass
Istiak Akib, François Hammer, Yanbin Yang
The timing argument (TA) aims to find the total mass of the Local Group (LG) from the relative motions of the Milky Way (MW) and Andromeda Galaxy (M31). However, the classical TA a…
An intriguing coincidence between the majority of vast polar structure dwarfs and a recent major merger at the M31 position
Istiak Akib, François Hammer, Yanbin Yang +2
A significant part of the Milky Way (MW) dwarf galaxies orbit within a Vast POlar Structure (VPOS), which is perpendicular to the Galactic disc and whose origin has not yet been id…
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…
