We analyze the stellar populations present in M31 by using nine sets of adjacent Hubble Space Telescope NICMOS camera 1 and 2 fields with galactocentric...
The Stellar Content of the Local Group Dwarf Galaxy PHOENIX
We present new deep VI ground-based photometry of the Local Group dwarf galaxy Phoenix. Our results confirm that this galaxy is mainly dominated by red stars...
The Stellar Content of the Pegasus Dwarf Irregular Galaxy
The stellar content and stellar age distribution of the Pegasus Dwarf Irregular Galaxy are discussed in the light of deep CM diagrams for (V - R) and (V - I)...
The StEllar Counterparts of COmpact high velocity clouds (SECCO) survey. I. Photos of ghosts
We present an imaging survey that searches for the stellar counterparts of recently discovered ultra-compact high-velocity H i clouds (UCHVC). It has been...
The StEllar Counterparts of COmpact high velocity clouds (SECCO) survey. II. Sensitivity of the survey and the atlas of synthetic dwarf galaxies
The searching for StEllar Counterparts of COmpact high velocity clouds (SECCO) survey is devoted to the search for stellar counterparts within ultra compact...
The stellar halo in Local Group Hestia simulations. I. The in situ component and the effect of mergers
Theory suggests that mergers play an important role in shaping galactic discs and stellar haloes, which was observationally confirmed in the Milky Way (MW)...
The stellar halo in Local Group Hestia simulations. II. The accreted component
Recent progress in understanding the assembly history of the Milky Way (MW) is driven by the tremendous amount of high-quality data delivered by Gaia (ESA)...
The stellar halo in Local Group Hestia simulations. III. Chemical abundance relations for accreted and in situ stars
Stellar chemical abundances and kinematics provide key information for recovering the assembly history of galaxies. In this work we explore the chemo-chrono...
We report on the detection of a stellar halo around NGC 1560, a 109 M ⊙ spiral galaxy member of the Maffei group. We obtained deep images in the r- and i-bands...
