Superdense massive galaxies in the nearby universe
At high-z the most superdense massive galaxies are supposed to be the result of gas-rich mergers resulting in compact remnant (Khochfar & Silk (2006); Naab et...
Superdense Massive Galaxies in Wings Local Clusters
Massive quiescent galaxies at z > 1 have been found to have small physical sizes, and hence to be superdense. Several mechanisms, including minor mergers, have...
Supergalactic Winds Driven by Multiple Super-Star Clusters
Here we present two-dimensional hydrodynamic calculations of free expanding supergalactic winds, taking into consideration strong radiative cooling. Our main...
Superluminal non-ballistic jet swing in the quasar NRAO 150 revealed by mm-VLBI
Context: NRAO 150, a compact and bright radio to mm source showing core/jet structure, has been recently identified as a quasar at redshift z = 1.52 through a...
Supermassive black hole wake or bulgeless edge-on galaxy?
A recent paper reported the serendipitous discovery of a thin linear object interpreted as the trail of star-forming regions left behind by a runaway...
Supermassive black hole wake or bulgeless edge-on galaxy?
A recent paper reported the serendipitous discovery of a thin linear object interpreted as the trail of star-forming regions left behind by a runaway...
Supermassive black hole wake or bulgeless edge-on galaxy?. II. Order-of-magnitude analysis of the two physical scenarios
Context. A recently discovered thin long object aligned with a nearby galaxy could be the stellar wake induced by the passage of a supermassive black hole (SMBH...
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...
