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

The abundance gradient in M 33 is studied on the basis of IPCS and CCD data on emission lines in selected H II regions, using O II, O III, S II, and S III in the wavelength range 3700-9600 A to refine the oxygen abundances in the inner parts as well as to study the behavior of S/O. Spatially resolved observations in each H II region permit the
