Detection of episodic Ultra-fast Outflows in the Low-luminosity quasar Mrk 205 using XMM-Newton data
César Ivan Victoria-Ceballos, Anna Lia Longinotti, Yair Krongold +3
Ultra-fast outflows (UFOs) from Active Galactic Nuclei (AGN) are winds which reach velocities up to 0.3c, and show mass outflow rates of 0.01-1 and kinetic ener…
Towards an observationally motivated AGN dusty torus model. I. Dust chemical composition from the modeling of Spitzer spectra
Omar Ulises Reyes-Amador, Jacopo Fritz, Omaira González-Martín +7
Spectral energy distribution (SED) fitting is one of most commonly used techniques to study the dust properties in Active Galactic Nuclei (AGN). Works implementing this technique c…
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…
The complex infrared dust continuum emission of NGC1068: ground-based N- and Q-band spectroscopy and new radiative transfer models
César Ivan Victoria-Ceballos, Omaira González-Martín, Jacopo Fritz +7
Thanks to ground-based infrared and sub-mm observations the study of the dusty torus of nearby AGN has greatly advanced in the last years. With the aim of further investigating the…
Observational hints on the torus obscuring gas behaviour through X-rays with NuSTAR data
Natalia Osorio-Clavijo, Omaira González-Martín, Sebastián F. Sánchez-Sánchez +5
According to theory, the torus of active galactic nuclei (AGN) is sustained from a wind coming off the accretion disk, and for low efficient AGN, it has been proposed that such str…
Active galactic nuclei ghosts: A systematic search for faded nuclei
Donaji Esparza-Arredondo, Natalia Osorio-Clavijo, Omaira González-Martín +5
Physical processes such as re-ignition, enhancement, and fading of active galactic nuclei (AGN) are not entirely understood because the timeline of these events is expected to last…
