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…
The Quasar Feedback Survey: Ionised Outflows in type 2 QSOs with MUSE data
M. Bianchin, C. M. Harrison, T. Costa +13
We study ionised gas properties in a sample of 18 luminous (log L erg/s) obscured QSOs at 0.085<z<0.2 observed with VLT/MUSE as part of the multi-wavelength Quasa…
Fuelling the central region of galaxies with misaligned gas accretion
J. L. Tous, S. I. Raimundo, R. Riffel +3
Recent studies have shown that the accretion of kinematically misaligned gas fuels the central reservoir of galaxies, triggering nuclear activity and star formation. In this work,…
Blowing star formation away in AGN hosts (BAH) -- V: The Feeding-Feedback Cycle in local AGNs as revealed by their stellar populations
Rogério Riffel, Rogemar A. Riffel, Gabriel L. Souza-Oliveira +9
We present a spatially resolved analysis of the stellar populations in the inner kiloparsec of NGC 3884, 3C 293, and CGCG 012-070. Using near-infrared spectroscopy, we reconstruct…
Identifying AGNs from X-ray detections-I: Metallicity calibrations in AGNs with X-ray luminosity as the primary input parameter
Mark Armah, O. L. Dors, Rogério Riffel +4
We present the first semi-empirical strong-line calibrations to determine metallicity in Active Galactic Nuclei (AGNs) that use the directly observable X-ray luminosity (Lx) instea…
