A forming, dust enshrouded disk at z=0.43: the first example of a late type disk rebuilt after a major merger?
F. Hammer, H. Flores, Y. B. Yang +4
Abreg: By combining HST/UDF imagery with kinematics from VLT/GIRAFFE we derive a physical model of distant galaxy J033245.11-274724.0 in a way similar to what can be done in the ne…
A giant bar induced by a merger event at z=0.4?
Sébastien Peirani, Francois Hammer, Hector Flores +2
(Aims) We present a physical model of the formation of J033239.72-275154.7, a galaxy observed at z=0.41 and characterized by a big young bar of size 6 kpc. The study of this system…
Dark Matter Accretion into Supermassive Black Holes
Sébastien Peirani, José Antonio De Freitas Pacheco
The relativistic accretion rate of dark matter by a black hole is revisited. Under the assumption that the phase space density indicator, , remains const…
Phase-Space Evolution of Dark Matter Halos
S. Peirani, J. A. de Freitas Pacheco
(Context) In a Universe dominated by dark matter, halos are continuously accreting mass (violently or not) and such mechanism affects their dynamical state. (Aims) The evolution of…
