On the origin of optical and IR emission lines in star forming galaxies
Mariela Martínez-Paredes, Gustavo Bruzual, Christophe Morisset +3
Combining the {\sc Cloudy} photoionization code with updated stellar population synthesis results, we simultaneously model the MIR $\neiii/\neii$ vs. $\oiv/\neiii$, the MIR-FIR $\n…
Chemical abundances in Seyfert galaxies X. Sulphur abundance estimates
O. L. Dors, M. Valerdi, R. A. Riffel +12
For the first time, the sulphur abundance relative to hydrogen (S/H) in the Narrow Line Regions of a sample of Seyfert 2 nuclei (Sy 2s) has been derived via direct estimation of th…
Electron Energy Distributions in the Extended Gas Nebulae associated with High-z AGN: Maxwell-Boltzmann vs. kappa distributions
S. G. Morais, A. Humphrey, M. Villar Martín +2
Emission line observations together with photoionization models provide important information about the ionization mechanisms, densities, temperatures, and metallicities in AGN-ion…
The peculiar emission line spectra of core-Extremely Red BOSS Quasars at 2-3: orientation and/or evolution?
Montse Villar Martin, Michele Perna, Andrew Humphrey +5
Core-extremely red quasars (core-ERQ) have been proposed to represent an intermediate evolutionary phase in which a heavily obscured quasar is blowing out the circumnuclear interst…
Multi-wavelength observations of the triple-peaked AGN Mrk 622
E. Benítez, I. Cruz-González, J. M. Rodríguez-Espinosa +8
A detailed multi-wavelength study of the properties of the triple-peaked AGN Mrk\,622 showing different aspects of the nuclear emission region is presented. Radio, near- and mid-in…
Photoionization models for extreme Ly 1216 and HeII 1640 ratios in quasar halos, and PopIII vs AGN diagnostics
A. Humphrey, M. Villar-Martín, L. Binette +1
We explore mechanisms to produce extremely high Ly-alpha/HeII flux ratios, or to enhance the observed number of Ly-alpha photons per incident ionizing photon, in extended AGN-photo…
