Here we stress some of the major differences between supergalactic winds and giant superbubbles evolving into the giant low density haloes of galaxies. Both...

At high-z the most superdense massive galaxies are supposed to be the result of gas-rich mergers resulting in compact remnant. After this, dry mergers are...

Supergiant Fast X-ray Transients have been recently unveiled as a new class of High Mass X-ray Binaries thanks to the excellent survey capabilities of the...

A possible correlation between spiral galaxy pitch angle (P) and the mass of the central supermassive black hole (SMBH) of the galaxy (M) was reported (Seigar...

Recently a tight correlation between the bulge velocity dispersion and the galaxy circular velocity has been found for a sample of spiral galaxies (Ferrarese...

Supermassive black holes are a key element in our understanding of how galaxies form. Most of the progress in this very active field of research is based on...
