We present an analysis of photometric and spectroscopic data of the Carina dSph galaxy, testing a new approach similar to that used to disentangle multiple populations in Galactic globular clusters (GCs). We show that a proper color combination is able to separate a significant fraction of the red giant branch (RGB) of the two main Carina

We have been intensively searching for PNe in nearby galaxies as one of the main objectives of the Local Group Census (LGC). The LGC is a narrow-band survey of the galaxies of the Local Group observable from La Palma, that was awarded observing time during period two of the ING Wide Field Imaging Survey programme (http://www.ing.iac.es/WFS/)

We have studied the colors of the bulge component of 133 galaxies from the HST Groth Strip Survey (Groth et al. 1994), covering redshifts 0.3 z 1.0. We selected all objects apparent radii R > 1.4'', and inclination above 50 degrees in order to avoid reddening from dust in the disk on one side of the bulges. We find that, as in the Local Universe

We present new high-resolution observations of the central region in the late-type spiral galaxy M100 (NGC 4321) supplemented by three-dimensional numerical modeling of stellar and gas dynamics, including star formation (SF). Near-infrared imaging has revealed a small bulge of 4" effective diameter; a 60" radial length stellar bar of moderate

The Century Survey is a photometric survey strip from which we select blue stars to probe the Milky Way halo. We obtain S/N=30 spectra for every star with (V-R)

We present new CCD narrowband images and spatially resolved intermediate-dispersion spectroscopy of the hydrogen-poor nebulae A30 and A58. These data have allowed us to obtain information on the physical properties and chemical abundances of the inner knots and outer envelopes of A30 and A58 as a basis for the discussion of their implications in
