Identifying AGNs from X-ray detectionsII: Metallicity calibrations for the and diagnostics

Mark Armah, O. L. Dors, Rogério Riffel +4

Emission-line ratios from ions with nearly identical ionization potentials offer a robust solution to the degeneracies inherent to traditional active galactic nuclei (AGNs) metalli…

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…

The interstellar medium of dwarf galaxies: new insights from Machine Learning analysis of emission line spectra

Graziano Ucci, Andrea Ferrara, Simona Gallerani +6

Dwarf galaxies are ideal laboratories to study the physics of the interstellar medium (ISM). Emission lines have been widely used to this aim. Retrieving the full information encod…

The Wolf-Rayet star population in the dwarf galaxy NGC 625

Ana Monreal-Ibero, Jeremy R. Walsh, Jorge Iglesias-Paramo +4

ABRIGED: Quantifying the number, type and distribution of W-R stars is a key component in the context of galaxy evolution, since they put constraints on the age of the star formati…

Extended nebular emission in CALIFA early-type galaxies

J. M. Gomes, P. Papaderos, C. Kehrig +3

The morphological, spectroscopic and kinematical properties of the warm interstellar medium (wim) in early-type galaxies (ETGs) hold key observational constraints to nuclear activi…

Star formation activity and gas stripping in the Cluster Projected Phase-Space (CPPS)

J. D. Hernandez-Fernandez, C. P. Haines, A. Diaferio +3

This work is focused on the study of the distribution in the CPPS of passive and star-forming galaxy populations and also, the intense and quiescent star-forming populations for a…

HeI in the central Giant HII Region of NGC 5253. A 2D observational approach to collisional and radiative transfer effects

A. Monreal-Ibero, J. R. Walsh, M. S. Westmoquette +1

ABRIDGED: NGC5253 is an ideal laboratory for detailed studies of starburst galaxies. We present for the first time in a starburst galaxy a 2D study of the spatial behavior of colli…

Complex gas kinematics in compact, rapidly assembling star-forming galaxies

Ricardo Amorín, José M. Vílchez, Guillermo Hägele +3

Deep, high resolution spectroscopic observations have been obtained for six compact, strongly star-forming galaxies at redshift z~0.1-0.3, most of them also known as Green Peas. Re…

A 2D multiwavelength study of the ionized gas and stellar population in the Giant HII Region NGC 588

A. Monreal-Ibero, M. Relaño, C. Kehrig +5

(ABRIDGED) We present an analysis of NGC588 based on IFS data with PMAS, together with Spitzer images at 8 mi and 24 mi. The extinction distribution in the optical shows complex st…

On the oxygen and nitrogen chemical abundances and the evolution of the "green pea" galaxies

Ricardo O. Amorín, E. Pérez-Montero, J. M. Vílchez

We have investigated the oxygen and nitrogen chemical abundances in extremely compact star-forming galaxies with redshifts between 0.11-0.35, popularly referred to as "green…
