On the use of the index N2 to derive the metallicity in metal-poor galaxie
A. B. Morales-Luis, E. Perez-Montero, J. Sanchez Almeida +1
The N2 index ([N II]6584/Ha) is used to determine emission line galaxy metallicities at all redshifts, including high redshift, where galaxies tend to be metal-poor. The initial ai…
3D spectroscopy of Wolf-Rayet HII galaxies
C. Kehrig, E. Perez-Montero, J. M. Vilchez +5
Wolf-Rayet (WR) HII galaxies are local metal-poor star-forming galaxies, observed when the most massive stars are evolving from O stars to WR stars, making them template systems to…
Ionizing stellar population in the disc of NGC 3310 - II. The Wolf-Rayet population
D. Miralles-Caballero, F. F. Rosales-Ortega, A. I. Díaz +3
We use integral field spectroscopy to study in detail the Wolf-Rayet (WR) population in NGC 3310, spatially resolving 18 star-forming knots with typical sizes of 200-300 pc in the…
MASSIV: Mass Assembly Survey with SINFONI in VVDS. VI. Metallicity-related fundamental relations in star-forming galaxies at
C. Divoy, T. Contini, E. Pérez-Montero +13
The MASSIV (Mass Assembly Survey with SINFONI in VVDS) project aims at finding constraints on the different processes involved in galaxy evolution. This study proposes to improve t…
The giant HII region NGC 588 as a benchmark for 2D photoionisation models
Enrique Perez-Montero, Ana Monreal-Ibero, Monica Relano +3
We use optical integral field spectroscopy and 8 and 24 micron mid-IR observations of the giant HII region NGC 588 in the disc of M33 as input and constraints for two-dimensional t…
Ionizing stellar population in the disk of NGC 3310 I. The impact of a minor merger on galaxy evolution
D. Miralles-Caballero, A. I. Díaz, F. F. Rosales-Ortega +2
Numerical simulations of minor mergers predict little enhancement in the global star formation activity. However, it is still unclear the impact they have on the chemical state of…
