Confidence limits of evolutionary synthesis models III. On time-integrated quantities
M. Cervino, M. A. Gomez-Flechoso, F. J. Castander +4
Evolutionary synthesis models are a fundamental tool to interpret the properties of observed stellar systems. In order to achieve a meaningful comparison between models and real da…
Structure in the Velocity Space of Globular Clusters
E. J. Alfaro, A. J. Delgado, M. A. Gomez-Flechoso +2
We present an analysis of the velocity space of a sample of globular clusters (GC) with absolute proper motions. The vertical component of the velocity is found to be correlated wi…
Radial Velocity of the Phoenix Dwarf Galaxy: Linking Gas and Hi Gas
C. Gallart, D. Martinez-Delgado, M. A. Gomez-Flechoso +1
We present the first radial velocity measurement of the stellar component of the Local Group dwarf galaxy Phoenix, using FORS1 at the VLT UT1 (ANTU) telescope. From the spectra of…
A tidal extension in the Ursa Minor dwarf spheroidal galaxy
D. Martinez-Delgado, J. Alonso-Garcia, A. Aparicio +1
We report the detection of main-sequence and blue horizontal-branch stars of the Ursa Minor dwarf spheroidal galaxy beyond its tidal radius, indicating the existence of a possible…
Is the Fast Evolution Scenario for Virialized Compact Groups Really Compelling? The Role of a Dark Massive Group Halo
M. A. Gomez-Flechoso, R. Dominguez-Tenreiro
We report on results of N-body simulations aimed at testing the hypothesis that galaxies in X-ray emitting (i.e., virialized) Compact Groups are not tidally stripped when they are…
