uvby{beta} photometry of h and chi Per
We present CCD uvby{beta} photometry for stars in the nuclei of the young double cluster {h} and {chi} Persei. We find that the reddening is highly variable through the {h} Per... -
HII regions in NGC 5457 and NGC 4395
Line intensities, visual extinction, abundances and ionization hardness parameter for HII regions in two spiral galaxies are presented. The following galaxies have been... -
ELG luminosity functions in the nearby Universe
Nebular emission lines are powerful diagnostics for the physical processes at play in galaxy formation and evolution. Moreover, emission-line galaxies (ELGs) are one of the main... -
PHANGS-MUSE sample HII regions catalog
We use an unprecedented sample of about 23000 HII regions detected at an average physical resolution of 67pc in the PHANGS-MUSE sample to study the extragalactic HII region... -
HII galaxies narrow-band Hbeta images
Our aims is to create a catalog of images of HII galaxies and their individual star-formation regions in order to study the distribution of the gas emission and their underlying... -
Southern reddened luminous stars. II.
H{beta} photometry is given for 263 reddened and very reddened stars from the Stephenson & Sanduleak (1971, Cat. ) catalogue of Luminous Stars in the Southern Milky Way...
