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…
Stellar Populations Found in the Central kpc of Four Luminous Compact Blue Galaxies at Intermediate Redshift
C. Hoyos, R. Guzman, A. I. Diaz +3
We investigate the star formation history of the central regions of four Luminous Compact Blue Galaxies (LCBGs). LCBGs are blue (B-V<0.6), compact (MU_B<21.5 mag arcsec^-2) galaxie…
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…
100 Years of dimensional analysis: New steps toward empirical law deduction
Michael Taylor, Angeles I. Diaz, Lucas A. Jodar-Sanchez +1
On the verge of the centenary of dimensional analysis (DA), we present a generalisation of the theory and a methodology for the discovery of empirical laws from observational data.…
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…
