Circumnuclear Regions of Star Formation in Early Type Galaxies
Angeles I. Diaz, Elena Terlevich, Guillermo F. Hagele +1
Circumnuclear star forming regions, also called hotspots, are often found in the inner regions of some spiral galaxies where intense processes of star formation are taking place. I…
Precision abundance analysis of bright HII galaxies
Guillermo F. Hagele, Angeles I. Diaz, Elena Terlevich +3
We present high signal-to-noise spectrophotometric observations of seven luminous HII galaxies. The observations have been made with the use of a double-arm spectrograph which prov…
The metal abundance of circumnuclear star forming regions in early type spirals. Spectrophotometric observations
Angeles I. Diaz, Elena Terlevich, Marcelo Castellanos +1
We have obtained long-slit observations in the optical and near infrared of 12 circumnuclear HII regions (CNSFR) in the early type spiral galaxies NGC 2903, NGC 3351 and NGC 3504 w…
Neon and Argon optical emission lines in ionized gaseous nebulae: Implications and applications
Enrique Perez-Montero, Guillermo F. Hagele, Thierry Contini +1
In this work we present a study of the strong optical collisional emission lines of Ne and Ar in an heterogeneous sample of ionized gaseous nebulae for which it is possible to deri…
Kinematics of gas and stars in the circumnuclear starforming ring of NGC 3351
Guillermo F. Hagele, Angeles I. Diaz, Monica V. Cardaci +2
We have measured gas and stellar velocity dispersions in 5 circumnuclear starforming regions (CNSFRs) and the nucleus of the barred spiral galaxy NGC 3351. The stellar dispersions…
