The WHaD diagram: Classifying the ionizing source with one single emission line
S. F. Sánchez, A. Z. Lugo-Aranda, J. Sánchez Almeida +4
The usual approach to classify the ionizing source using optical spectroscopy is based on the use of diagnostic diagrams that compares the relative strength of pairs of collisition…
Multi-phase characterization of AGN winds in 5 local type-2 quasars
G. Speranza, C. Ramos Almeida, J. A. Acosta-Pulido +9
We present MEGARA (Multi-Espectrógrafo en GTC de Alta Resolución para Astronomía) Integral Field Unit (IFU) observations of 5 local type-2 quasars (QSO2s, z ) from the Qu…
Testing physical scenarios for the reflection features of type-1 AGN using XMM-Newton and NuSTAR simultaneous observations
César Ivan Victoria-Ceballos, Omaira González-Martín, Josefa Masegosa +3
Above 3 keV, the X-ray spectrum of the active galactic nuclei (AGN) is characterized by the intrinsic continuum and compton reflection features. For type-1 AGN, several regio…
Variability and evolution of the optical polarization of a sample of gamma-ray blazars
J. Otero-Santos, J. A. Acosta-Pulido, J. Becerra González +5
We present a polarization variability analysis of a sample of 26 -ray blazars monitored by the Steward Observatory between 2008 and 2018 in the optical band. We investigate the…
Peering into the central region of a nano-quasar: XMM-Newton and Chandra views of the CH Cyg Symbiotic System
J. A. Toalá, O. González-Martín, M. Karovska +3
We present the analysis of archival XMM-Newton and Chandra observations of CH Cyg, one of the most studied symbiotic stars (SySts). The combination of the high-resolution XMM-Newto…
AGN in the CALIFA survey: X-ray detection of nuclear sources
Natalia Osorio-Clavijo, Omaira González-Martín, Sebastián F. Sánchez-Sánchez +2
A complete demographic of active galactic nuclei (AGN) is essential to understand the evolution of the Universe. Optical surveys estimate the population of AGN in the local Univers…
