Supergiant Fast X-ray Transients: an INTEGRAL view
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...
Supermassive Black Hole Mass and Spiral Galaxy Pitch Angle at Intermediate to High Redshift
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 from OASIS and SAURON integral-field kinematics
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...
