The faint extended broad (>=1000 km s-1) optical emission lines associated with giant H II regions are shown here to be produced in a shell of ISM material...

We present a new method for the detection and characterization of expansion in galaxy discs based on Hα Fabry-Perot spectroscopy, taking advantage of the high...

We compare the rate of kinetic energy injected by stellar winds into the extragalactic H II region NGC 2363 to the luminosity needed to feed the observed...

We present deep spectrophotometry of several H II regions in the nearby low-mass spiral galaxies NGC 300 and M33. The data have been taken with Ultraviolet...

We have measured C II and O II recombination lines in several H II regions of low-metallicity dwarf galaxies. These objects show lower C/O ratios than H II...

We present deep echelle spectrophotometry of the brightest emission-line knots of the star-forming galaxies He 2-10, Mrk 1271, NGC 3125, NGC 5408, POX 4, SDSS...

We present results of deep echelle spectrophotometry of eight Galactic H II regions located at Galactocentric distances between 6.3 and 10.4 kpc. The data have...

We present C and O abundances in the Magellanic Clouds derived from deep spectra of H II regions. The data have been taken with the Ultraviolet-Visual Echelle...
