Spectroscopy of the short-hard GRB 130603B: The host galaxy and environment of a compact object merger
A. de Ugarte Postigo, C. C. Thoene, A. Rowlinson +40
Short duration gamma-ray bursts (SGRBs) are thought to be related to the violent merger of compact objects, such as neutron stars or black holes, which makes them promising sources…
Modelling narrow-line regions of active galaxies in the Sloan Digital Sky Survey - I.Sample selection and physical conditions
Zhitai Zhang, Yanchun Liang, François Hammer
We systematically determine the electron density and electron temperature of active galaxies and star-forming galaxies using spectroscopy from the SDSS DR7, while mainly focusing o…
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…
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…
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…
Could M31 be the result of a major merger?
Sylvain Fouquet, François Hammer, Yang-Bin Yang +3
We investigated a scenario in which M31 could be the remnant of a gas-rich major merger. Galaxy merger simulations, highly constrained by observations, were run using GADGET 2 in o…
