Primordial helium abundance determination using sulphur as metallicity tracer

Vital Fernández, Elena Terlevich, Angeles I. Díaz +2

The primordial helium abundance $Y_{P}$ is calculated using sulphur as metallicity tracer in the classical methodology (with $Y_{P}$ as an extrapolation of $Y$ to zero metals). The cal…

Direct determination of oxygen abundances in line emitting star-forming galaxies at intermediate redshift

José M. Pérez, Carlos Hoyos, Ángeles I. Díaz +2

We present a sample of 22 blue ( $(B - V)_{A B} < 0.45$ ), luminous ( $M_{B, A B} < - 18.9$ ), metal-poor galaxies in the $0.69 < z < 0.88$ redshift range, selected from the DEEP2 galaxy redshift su…

Star Formation in HII Galaxies. Properties of the ionized gas

G. F. Hagele, A. I. Diaz, E. Terlevich +3

We propose a methodology to perform a self-consistent analysis of the physical properties of the emitting gas of HII galaxies adequate to the data that can be obtained with the XXI…
