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…
The role of grain size in AGN torus dust models
Omaira González-Martín, Cristina Ramos Almeida, Jacopo Fritz +10
Fits the infrared spectra from the nuclear regions of AGN can place constraints on the dust properties, distribution, and geometry by comparison with models. However, none of the c…
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…
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…
