On the distance and reddening of the starburst galaxy IC10
N. Sanna, G. Bono, P. B. Stetson +16
We present deep and accurate optical photometry of the Local Group starburst galaxy IC10. The photometry is based on two sets of images collected with the Advanced Camera for Surve…
Matching the Local and Cosmic Star Formation Histories
Igor Drozdovsky, Andrew M. Hopkins, Antonio Aparicio +2
Given the many recent advances in our understanding of the star formation history (SFH) of the Local Group and other nearby galaxies, and in the evolution of star formation with re…
VV124 (UGC4879): A new transitional dwarf galaxy in the periphery of the Local Group
Alexander I. Kopylov, Nikolay A. Tikhonov, Sergey Fabrika +2
We present the first resolved-star photometry of VV124 (UGC4879) and find that this is the most isolated dwarf galaxy in the periphery of the Local Group. Based on imaging and spec…
The ACS LCID Project: RR Lyrae stars as tracers of old population gradients in the isolated dwarf spheroidal galaxy Tucana
Edouard J. Bernard, Carme Gallart, Matteo Monelli +9
We present a study of the radial distribution of RR Lyrae variables, which present a range of photometric and pulsational properties, in the dwarf spheroidal galaxy Tucana. We find…
Short-Period Variables in the Local Group Dwarf Galaxies Tucana and LGS3
E. J. Bernard, M. Monelli, C. Gallart +16
We present preliminary results concerning the search for short-period variable stars in Tucana and LGS3 based on very deep HST/ACS imaging. In the fraction of the observed field we…
Stellar halos and thick disks around edge-on spiral galaxies IC2233, IC5052, NGC4631 and NGC5023
N. A. Tikhonov, O. A. Galazutdinova, I. O. Drozdovsky
Aims. The extraplanar stellar populations of highly-inclined disk galaxies IC 2233, IC 5052, NGC 4631 and NGC 5023 are analyzed with the goal to quantify their vertical extent and…
