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…
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…
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…
The origin of the mid-infrared nuclear polarization of active galactic nuclei
E. Lopez-Rodriguez, A. Alonso-Herrero, T. Diaz-Santos +10
We combine new (NGC 1275, NGC 4151, and NGC 5506) and previously published (Cygnus A, Mrk 231, and NGC 1068) sub-arcsecond resolution mid-infrared (MIR; 8-13 m) imaging- and spe…
Circumnuclear star-formation and AGN activity: Clues from surface brightness radial profile of PAHs and [SIV]
Donaji Esparza-Arredondo, Omaira Gonzalez-Martin, Deborah Dultzin +6
We studied the circumnuclear MIR emission in a sample of 19 local active galactic nuclei (AGN) with high spatial resolution spectra using T-ReCS (Gemini) and CanariCam (GTC), toget…
Hints on the gradual re-sizing of the torus in AGN by decomposing IRS/Spitzer spectra
O. González-Martín, J. Masegosa, A. Hernán-Caballero +12
Several authors have claimed that the less luminous active galactic nuclei (AGN) are not capable of sustaining the dusty torus structure. Thus, a gradual re-sizing of the torus is…
The complex evolutionary paths of local infrared bright galaxies: a high angular resolution mid-infrared view
A. Alonso-Herrero, R. Poulton, P. F. Roche +15
We investigate the evolutionary connection between local IR-bright galaxies () and quasars. We use high angular resolution ( 0.3-0.4 arcsec…
