Gas accretion and counter-rotation in disk galaxies: N-body simulations of mergers with a dwarf galaxy

Dopo un'introduzione alla controrotazione nelle galassie a disco e al ruolo svolto a riguardo dalle fusioni con le galassie nane, presento il codice a N- corpi ChaNGa e mostro i risultati di un testo comparativo con un altro codice, gasoline. Infine, discuto i risultati di alcune simulazioni a N-corpi di fusioni tra una galassia a disco e una galassia ...

Turbulent viscosity in clumpy accretion disks [PDF]

Astronomy and Astrophysics, 2002
The equilibrium state of a turbulent clumpy gas disk is analytically investigated. The disk consists of distinct self-gravitating clouds. Gravitational cloud-cloud interactions transfer energy over spatial scales and produce a viscosity, which allows mass accretion in the gas disk.

The Relative Orientation of Nuclear Accretion and Galaxy Stellar Disks in Seyfert Galaxies [PDF]

Astrophysical Journal, 1999
We use the difference (delta) between the position angles of the nuclear radio emission and the host galaxy major axis to investigate the distribution of the angle (beta) between the axes of the nuclear accretion disk and the host galaxy disk in Seyfert galaxies. We provide a critical appraisal of the quality of all measurements, and find that the data
