Jet collimation in NGC 315 and other nearby AGN
B. Boccardi, M. Perucho, C. Casadio +14
Aims. The collimation of relativistic jets in galaxies is a poorly understood process. Detailed radio studies of the jet collimation region have been performed so far in few indivi…
MAORY AO performances
Guido Agapito, Cedric Plantet, Lorenzo Busoni +7
The Multi-conjugate Adaptive Optics RelaY (MAORY) should provide 30% SR in K band (50% goal) on half of the sky at the South Galactic Pole. Assessing its performance and the sensit…
Illuminating the dark side of cosmic star formation two billion years after the Big Bang
Margherita Talia, Andrea Cimatti, Marika Giulietti +5
How and when did galaxies form and assemble their stars and stellar mass? The answer to these questions, so crucial to astrophysics and cosmology, requires the full reconstruction…
Icarus: a Flat and Fast Prograde Stellar Stream in the Milky Way disk
Paola Re Fiorentin, Alessandro Spagna, Mario G. Lattanzi +1
We explore the local volume of the Milky Way via chemical and kinematical measurements from high quality astrometric and spectroscopic data recently released by the Gaia, APOGEE an…
The updated BaSTI stellar evolution models and isochrones: II. alpha-enhanced calculations
A. Pietrinferni, S. L. Hidalgo, S. Cassisi +7
This is the second paper of a series devoted to present an updated release of the BaSTI ( a Bag of Stellar Tracks and Isochrones) stellar model and isochrone library. Following the…
Observational Evidence for Enhanced Black Hole Accretion in Giant Elliptical Galaxies
Michael McDonald, Brian R. McNamara, Michael S. Calzadilla +5
We present a study of the relationship between black hole accretion rate (BHAR) and star formation rate (SFR) in a sample of giant elliptical galaxies. These galaxies, which live a…
