چکیده
Rapid infall of gas in the nuclei of galaxies could lead to the formation of black holes by direct collapse, without first forming stars. Black holes formed in this way would have initial masses of a few M⊙, but would be embedded in massive envelopes that would allow them to grow at a highly super-Eddington rate. Thus, seed black holes as large as 103 − 10M⊙ could form very rapidly. I will sketch the basic physics of the direct collapse process and the properties of the accreting envelopes.

The dynamics of galactic nuclei reflects the presence of supermassive black holes (SBHs) in many ways. Single SBHs act as sinks, destroying a mass in stars equal to their own mass in roughly one relaxation time and forcing nuclei to expand. Formation of binary SBHs displaces a mass in stars roughly equal to the binary mass, creating low-density cores and ejecting hyper-velocity stars. Gravitati...

The properties of their hosts provide important clues to the progenitors of different classes of gamma-ray bursts (GRBs). The hosts themselves also constitute a sample of high-redshift star-forming galaxies which, unlike most other methods, is not selected on the luminosities of the galaxies themselves. We discuss what we have learnt from and about GRB host galaxies to date.

We present measurements with the VLBA of the variability in the centroid position of Sgr A* relative to a background quasar at 7mm wavelength. We find an average centroid wander of 71 ± 45μas for time scales between 50 and 100 min and 113± 50μas for timescales between 100 and 200 min, with no secular trend. These are sufficient to begin constraining the viability of the accretion hot-spot model...
