The Gran Telescopio Canarias (GTC), a 10 meter segmented-mirror telescope, now at an advanced stage of construction on La Palma (Spain), will shortly be...
The HII regions of M51 and NGC 4449. Behavior of the mean electron density
With ACS-HST images we produced continuum subtracted photometric maps in Hα for the galaxies M51 and NGC 4449. From the Hα luminosity (L), equivalent radius (R)...
The homogeneity of chemical abundances in H II regions of the Magellanic Clouds
We use very deep spectra obtained with the Ultraviolet-Visual Echelle Spectrograph at the Very Large Telescope to derive physical conditions and chemical...
The hydrodynamics and ionization structure of gaseous nebulae. I. The time-dependent solution
We present a one-dimensional numerical scheme that allows for the simultaneous solution of the hydrodynamic equations coupled with energy and ionization...
The internal dynamical equilibrium of H II regions: A statistical study
We present an analysis of the integrated Hα emission line profiles for the H SHAPE Ii region population of the spiral galaxies NGC 1530, NGC 6951 and NGC 3359...
The ionized gas in the spiral galaxy NGC 3359. I. Photometry
We combine Hα imaging and broad-band optical and NIR imaging over the face of the barred galaxy NGC 3359, obtained within the BARS program on the Canary Island...
The JCMT Nearby Galaxies Legacy Survey - VII. Hα imaging and massive star formation properties
We present Hα fluxes, star formation rates (SFRs) and equivalent widths (EWs) for a sample of 156 nearby galaxies observed in the 12CO J= 3-2 line as part of...
The origin of the ionization of the diffuse interstellar medium in spiral galaxies. I. Photometric measurements
We present a complete study of the diffuse ionized gas (DIG) in a sample of six spiral galaxies (NGC 157, NGC 3359, NGC 3631, NGC 6764, NGC 6951, NGC 7479)...
