Chemical abundances of Seyfert 2 AGNs I. Comparing oxygen abundances from distinct methods using SDSS
O. L. Dors, P. Freitas-Lemes, E. B. Amores +6
We compare the oxygen abundance (O/H) of the Narrow Line Regions (NLRs) of Seyfert 2 AGNs obtained through strong-line methods and from direct measurements of the electron temperat…
Searching for intergalactic star forming regions in Stephan's Quintet with SITELLE. I. Ionised gas structures and kinematics
S. Duarte Puertas, J. Iglesias-Páramo, J. M. Vilchez +3
Stephan's Quintet (SQ), the prototypical compact group of galaxies in the local Universe, has been observed with the imaging Fourier transform spectrometer SITELLE, attached to the…
A bayesian-like approach to derive chemical abundances in Type-2 Active Galactic Nuclei based on photoionization models
E. Pérez-Montero, O. L. Dors, J. M. Vílchez +3
We present a new methodology for the analysis of the emission lines of the interstellar medium in the Narrow Line Regions around type-2 Active Galactic Nuclei. Our aim is to provid…
