I have performed a set of hydrodynamic simulations of multiple galaxy mergers both with and without a cosmological context using Gadget. Using a set of existing simulations of binary mergers of gas-rich spiral galaxies, I found that the simulated...

The formation and evolution of the giant planets of our Solar System presents several problems: the cores of the planets should have been driven into the Sun by Type I migration, faster than they could accrete their massive gaseous atmosphere; once...

The X-ray flux of accreting black holes occasionally shows a pair of quasi-periodic oscillations with frequencies in a 3:2 ratio having values comparable to the orbital frequency at the innermost stable circular orbit. The cause and nature of...
