The DESIRED strong-line calibrations: I. New empirical metallicity relations for the local and high-redshift universe
F. F. Rosales-Ortega, J. E. Méndez-Delgado, J. U. Guerrero-González +16
We present the most comprehensive set of empirical optical strong-line metallicity calibrations to date, based on the DEep Spectra of Ionised REgions Database (DESIRED), the larges…
Exploring Emission Line Variability and Jet-Broad Line Region Interaction in the Blazar TON 599
Jonhatan U. Guerrero-González, Vahram Chavushyan, VÃctor M. Patiño-Ãlvarez
Blazars, a highly variable Active Galactic Nuclei (AGNs) subclass, provide a unique opportunity to explore the physical processes within their relativistic jets and emission region…
The Relationship Between Emission Line and Continuum Luminosity and the Baldwin Effect in Blazars. I. The Case of the Mg II λ2798 à Emission Line
VÃctor M. Patiño-Ãlvarez, Jonhatan U. Guerrero-González, Vahram Chavushyan +3
Aims. This study investigates the relationship between the Mg II λ2798 à emission line and the 3000 à continuum luminosity, as well as the Baldwin Effect, in a sample of 40,685 ra…
