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…
Cold molecular gas and PAH emission in Seyfert galaxies
A. Alonso-Herrero, M. Pereira-Santaella, D. Rigopoulou +15
We investigate the relation between the detection of the m PAH feature in the nuclear (pc) regions of 22 nearby Seyfert galaxies and the properties of the c…
Modelling the strongest silicate emission features of local type 1 AGN
M. Martínez-Paredes, O. González-Martín, D. Esparza-Arredondo +8
We measure the 10 and m silicate features in a sample of 67 local () type 1 active galactic nuclei (AGN) with available {\it Spitzer} spectra dominated by non-stellar p…
Physical parameters of the torus for the type 2 Seyfert IC 5063 from mid-IR and X-ray simultaneous spectral fitting
Donaji Esparza-Arredondo, Omaira González-Martín, Deborah Dultzin +7
In order to understand the diversity of classes observed in active galactic nuclei (AGN), a geometrically and optically thick torus of gas and dust is required to obscure the centr…
Exploring the mid-infrared SEDs of six AGN dusty torus models II: the data
O. González-Martín, J. Masegosa, I. García-Bernete +9
This is the second in a series of papers devoted to explore a set of six dusty models of active galactic nuclei (AGN) with available spectral energy distributions (SEDs). These mod…
Exploring the mid-infrared SEDs of six AGN dusty torus models I: synthetic spectra
O. González-Martín, J. Masegosa, I. García-Bernete +9
At distances from the active galaxy nucleus (AGN) where the ambient temperature falls below ~1500-1800 K, dust is able to survive. It is thus possible to have a large dusty structu…
