Accretion-regulated star formation in late-type galaxies
Accretion-regulated star late-type galaxies

2010/11/15
We develop a four-phase galaxy evolution model in order to study the effect of accretion of extra-galactic gas on the star formation rate (SFR) of a galaxy. Pure self-regulated star formation of isola...
A2163: Merger events in the hottest Abell galaxy cluster II. Subcluster accretion with galaxy-gas separation
Galaxies clusters general – Galaxies intergalactic medium – X-rays galaxies clusters

2010/11/16
Located at z = 0.203, A2163 is a rich galaxy cluster with an intra-cluster medium (ICM) that exhibits extraordinary properties,including an exceptionally high X-ray luminosity, average temperature, an...
The rates and modes of gas accretion on to galaxies and their gaseous haloes
galaxies evolution – galaxies formation – intergalactic medium – cos-mology theory

2010/11/15
We study the rate at which gas accretes on to galaxies and haloes and investigate whether the accreted gas was shocked to high temperatures before reaching a galaxy.For this purpose we use a suite of ...
Retrograde Accretion and Merging Supermassive Black Holes

2010/11/12
We investigate whether a circumbinary gas disc can coalesce a supermassive black hole
binary system in the centre of a galaxy. This is known to be problematic for a prograde disc.
We show that in co...
The fragmentation of expanding shells III: Oligarchic accretion and the mass spectrum of fragments
Galaxy Astrophysics (astro-ph.GA)

2010/12/28
We use SPH simulations to investigate the gravitational fragmentation of expanding shells through the linear and non--linear regimes.
