Spectral Synthesis of SDSS Galaxies
L. Sodre, R. Cid Fernandes, A. Mateus +2
We investigate the power of spectral synthesis as a mean to estimate physical properties of galaxies. Spectral synthesis is nothing more than the decomposition of an observed spect…
Modelling of aspherical nebulae. I. A quick pseudo-3D photoionization code
C. Morisset, G. Stasinska, M. Pena
We describe a pseudo-3D photoionization code, NEBU_3D and its associated visualization tool, VIS_NEB3D, which are able to easily and rapidly treat a wide variety of nebular geometr…
The emission line sequence of H II galaxies
G. Stasinska, Y. Izotov
We consider 400 H II galaxies in which the oxygen abundances were obtained by electron temperature based methods. We split the sample in three metallicity bins. In each bin, a narr…
The electron temperature in ionized nebulae
Grazyna Stasinska
We discuss the role of the electron temperature in abundance determinations in ionized nebulae (planetary nebulae and giant HII regions). We show that, even when observations provi…
What heats the bright HII regions in I Zw 18?
Grazyna Stasinska, Daniel Schaerer
We have used the radiation field from a starburst population synthesis model appropriate for the brightest HII region of IZw 18 to perform a photoionization model analysis of this…
On the origin of [OIV] emission in Wolf-Rayet galaxies
Daniel Schaerer, Grazyna Stasinska
We propose that the emission of the high excitation [OIV] line observed with ISO in NGC 5253 and II Zw 40 is due to the presence of hot Wolf-Rayet (WR) stars in these objects. We c…
