Detection of satellite remnants in the Galactic Halo with Gaia III. Detection limits for Ultra Faint Dwarf Galaxies
Teresa Antoja, Cecilia Mateu, Luis Aguilar +8
We present a method to identify Ultra Faint Dwarf Galaxy (UFDG) candidates in the halo of the Milky Way using the future Gaia catalogue and we explore its detection limits and comp…
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…
GARROTXA Cosmological Simulations of Milky Way-sized Galaxies: General Properties, Hot Gas Distribution, and Missing Baryons
Santi Roca-Fàbrega, Octavio Valenzuela, Pedro Colín +5
We introduce a new set of simulations of Milky Way-sized galaxies using the AMR code ART + hydrodynamics in a CDM cosmogony. The simulation series is named GARROTXA and follow t…
First detection of the field star overdensity in the Perseus arm
Maria Monguió, Preben Grosbøl, Francesca Figueras
Aims. The main goal of this study is to detect the stellar overdensity associated with the Perseus arm in the anticenter direction. Methods. We used the physical parameters derived…
