Towards an observationally motivated AGN dusty torus model -- II. The roles of density distribution and chemical composition of the dust

Omar Ulises Reyes-Amador, Omaira González-Martín, Jacopo Fritz +5

Several models of nuclear dust in active galactic nuclei (AGN) have been presented in the literature to determine its physical and geometrical properties, usually assuming the dust…

ELLIPSECT: A surface brightness analysis tool for GALFIT 3

Christopher Añorve, Omar Ulises Reyes-Amador, Emmanuel Ríos-López +2

EllipSect is a user-friendly analysis and measurement tool, implemented in Python, that operates on the imaging data together with the output of the widely used 2D surface-brightne…

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…

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…
