A possible impact near the Milky Way of a former major merger in the Local Group
Sylvain Fouquet, François Hammer, Yanbin Yang +2
The Milky Way (MW) dwarf system presents two exceptional features, namely it forms a thick plane called the Vast Polar Structure (VPOS), and the two biggest dwarves, the Magellanic…
Does the dwarf galaxy system of the Milky Way originate from Andromeda?
Sylvain Fouquet, François Hammer, Yanbin Yang +2
The Local Group is often seen to be a quiescent environment without significant merger events. However an ancient major merger may have occurred in the most massive galaxy. Numeric…
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…
GRB 100219A with X-shooter - abundances in a galaxy at z = 4.7
C. C. Thoene, J. P. U. Fynbo, P. Goldoni +24
Abundances of galaxies at redshifts z > 4 are difficult to obtain from damped Ly α (DLA) systems in the sightlines of quasars (QSOs) due to the Ly α forest blanketing and the low n…
A decrease of the gas exchanges between galaxies and the IGM, from 12 to 6 billion years ago
M. Rodrigues, M. Puech, F. Hammer +2
Using a representative sample of 65 intermediate mass galaxies at z \sim 0.6, we have inves- tigated the interplay between the main ingredients of chemical evolution: metal abundan…
