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…
Absence of nuclear polycyclic aromatic hydrocarbon emission from a compact starburst: The case of the type-2 quasar Mrk 477
C. Ramos Almeida, D. Esparza-Arredondo, O. Gonzalez-Martin +11
Mrk 477 is the closest type-2 quasar (QSO2), at a distance of 163 Mpc. This makes it an ideal laboratory for studying the interplay between nuclear activity and star formation with…
