The ACS LCID Project. II. Faint Variable Stars in the Isolated Dwarf Irregular Galaxy IC1613 (2010)
Bernard, Edouard J., Monelli, Matteo, Gallart, Carme, Aparicio, Antonio, Cassisi, Santi, Drozdovsky, Igor, ...
(Abridged) We present the results of a new search for variable stars in the Local Group (LG) isolated dwarf galaxy IC1613, based on 24 orbits of F475W and F814W photometry from the ACS camera onboard...
Bernard, Edouard J., Monelli, Matteo, Gallart, Carme, Drozdovsky, Igor, Stetson, Peter B., Aparicio, Antonio, ...
(abridged) We present the first study of the variable star populations in the isolated dwarf spheroidal galaxies (dSph) Cetus and Tucana. Based on Hubble Space Telescope images obtained with the...
Bernard, Edouard J., Gallart, Carme, Monelli, Matteo, Aparicio, Antonio, Cassisi, Santi, Skillman, Evan D., ...
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 that the fainter...
The stellar structures around disk galaxies (2007)
Antonio Aparicio, Carme Gallart, Edouard J. Bernard, Igor Drozdovsky, Matteo Monelli, Nikolay Tikhonov, ...
We present a brief summary of current results on the stellar distribution and population gra- dients in disk galaxies, and discuss future prospects of follow-up imaging and spectro- scopic research...
Stellar populations in the Carina dSph galaxy and in the globular cluster Omega Centauri (2004)
ABSTRACT Dwarf spheroidal galaxies (dSphs) in the Local Group are fundamental laboratories to constrain not only cosmological theories concerning the so-called hierarchical paradigm, but also to...
