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…
LAMOST observations in the Kepler field. Database of low-resolution spectra
P. De Cat, J. N. Fu, A. B. Ren +34
The nearly continuous light curves with micromagnitude precision provided by the space mission Kepler are revolutionising our view of pulsating stars. They have revealed a vast sea…
Galaxy disks do not need to survive in the L-CDM paradigm: the galaxy merger rate out to z~1.5 from morpho-kinematic data
M. Puech, F. Hammer, P. F. Hopkins +5
About two-thirds of present-day, large galaxies are spirals such as the Milky Way or Andromeda, but the way their thin rotating disks formed remains uncertain. Observations have re…
The Milky Way and other spiral galaxies
F. Hammer, M. Puech, H. Flores +3
Cosmologists have often considered the Milky Way as a typical spiral galaxy, and its properties have considerably influenced the current scheme of galaxy formation. Here we compare…
The Formation of Large Galactic Disks: Revival or Survival?
F. Hammer, M. Puech, H. Flores +5
Using the deepest and the most complete set of observations of distant galaxies, we investigate how extended disks could have formed. Observations include spatially-resolved kinema…
Could M31 come from a major merger and eject the LMC away?
S. Fouquet, F. Hammer, Y. B. Yang +3
We investigated a scenario in which M31 could be the remnant of a major merger and at the origin of the LMC. Galaxy merger simulations were run in order to reproduce some M31 prope…
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…
Luminous Infrared Galaxies in the Local Universe
J. L. Wang, X. Y. Xia, S. Mao +3
We study the morphology and star formation properties of 159 local luminous infrared galaxy (LIRG) using multi-color images from Data Release 2 (DR2) of the Sloan Digital Sky Surve…
