The large-scale structure of the halo of the Andromeda galaxy II. Hierarchical structure in the Pan-Andromeda Archaeological Survey
Alan W. McConnachie, Rodrigo Ibata, Nicolas Martin +29
The Pan-Andromeda Archaeological Survey is a survey of square degrees centered on the Andromeda (M31) and Triangulum (M33) galaxies that has provided the most extensive pano…
A high-resolution mosaic of the neutral hydrogen in the M81 triplet
W. J. G. de Blok, Fabian Walter, Annette M. N. Ferguson +10
We present a 3x3 degrees, 105-pointing, high-resolution neutral hydrogen (HI) mosaic of the M81 galaxy triplet (including the galaxies M81, M82 and NGC 3077, as well as dwarf galax…
Variable Stars in Local Group Galaxies. IV. RR Lyrae stars in the central regions of the low-density galaxy Crater II
M. Monelli, A. R. Walker, C. E. Martìnez-Vàzquez +9
We present a search and analysis of variable stars in the recently discovered Crater~II dwarf galaxy. Based on , , data collected with the Isaac Newton Telescope (FoV$\si…
Integrated-light analyses vs. colour-magnitude diagrams - II. Leo A, an extremely young dwarf in the Local Group
T. Ruiz-Lara, C. Gallart, M. Beasley +7
Context. Most of our knowledge on the stellar component of galaxies is based on the analysis of distant systems and comes from integrated light data. It is important to test whethe…
Gaia DR1 completeness within 250 pc and star formation history of the Solar neighbourhood
Edouard J. Bernard
Taking advantage of the Gaia DR1, we combined TGAS parallaxes with the Tycho-2 and APASS photometry to calculate the star formation history (SFH) of the solar neighbourhood within…
Star formation history of the Galactic bulge from deep HST imaging of low reddening windows
Edouard J. Bernard, Mathias Schultheis, Paola Di Matteo +3
Despite the huge amount of photometric and spectroscopic efforts targetting the Galactic bulge over the past few years, its age distribution remains controversial owing to both the…
