Gaia
C. Cacciari, E. Pancino, M. Bellazzini
A review of the Gaia mission and its science performance after one year of operations will be presented, and the contribution to reconstructing the history of the Milky Way will be…
Deep multi-telescope photometry of NGC 5466. II. The radial behaviour of the mass function slope
Giacomo Beccari, Emanuele Dalessandro, Barbara Lanzoni +3
We use a combination of data acquired with the Advanced Camera for Survey (ACS) on board the Hubble Space Telescope and the Large Binocular Camera (LBC-blue) mounted on the Large B…
Chemical abundances of giant stars in NGC 5053 and NGC 5634, two globular clusters associated with the Sagittarius dwarf Spheroidal galaxy?
L. Sbordone, L. Monaco, C. Moni Bidin +8
The tidal disruption of the Sagittarius dwarf Spheroidal galaxy (Sgr dSph) is producing the most prominent substructure in the Milky Way (MW) halo, the Sagittarius Stream. Aside fr…
A method for space-variant deblurring with application to adaptive optics imaging in astronomy
Andrea La Camera, Laura Schreiber, Emiliano Diolaiti +4
Images from adaptive optics systems are generally affected by significant distortions of the point spread function (PSF) across the field of view, depending on the position of natu…
The Gaia spectrophotometric standard stars survey -II. Instrumental effects of six ground-based observing campaigns
G. Altavilla, S. Marinoni, E. Pancino +16
The Gaia SpectroPhotometric Standard Stars (SPSS) survey started in 2006, it was awarded almost 450 observing nights, and accumulated almost 100,000 raw data frames, with both phot…
The Gaia-ESO Survey: A globular cluster escapee in the Galactic halo
K. Lind, S. E. Koposov, C. Battistini +37
A small fraction of the halo field is made up of stars that share the light element (Z<=13) anomalies characteristic of second generation globular cluster (GC) stars. The ejected s…
