Uncovering the deeply embedded AGN activity in the nuclear regions of the interacting galaxy Arp299
A. Alonso-Herrero, P. F. Roche, P. Esquej +14
We present mid-infrared (MIR) 8-13micron spectroscopy of the nuclear regions of the interacting galaxy Arp299 (IC694+NGC3690) obtained with CanariCam (CC) on the 10.4m Gran Telesco…
Nuclear star formation activity and black hole accretion in nearby Seyfert galaxies
P. Esquej, A. Alonso-Herrero, O. González-Martín +10
Recent theoretical and observational works indicate the presence of a correlation between the star formation rate (SFR) and the active galactic nuclei (AGN) luminosity (and, theref…
The role of the accretion disk, dust, and jets in the IR emission of low-luminosity AGN
R. E. Mason, C. Ramos Almeida, N. A. Levenson +2
We use recent high-resolution infrared (IR; 1 - 20 micron) photometry to examine the origin of the IR emission in low-luminosity active galactic nuclei (LLAGN). The data are compar…
Estimations of the magnetic field strength in the torus of AGN using near-infrared polarimetry
E. Lopez-Rodriguez, C. Packham, S. Young +7
An optically and geometrically thick torus obscures the central engine of Active Galactic Nuclei (AGN) from some lines of sight. From a magnetohydrodynamical framework, the torus c…
A sample of Seyfert-2 galaxies with ultra-luminous galaxy-wide NLRs -- Quasar light echos?
Mischa Schirmer, Ruben Diaz, Karianne Holhjem +2
We report the discovery of Seyfert-2 galaxies in SDSS-DR8 with galaxy-wide, ultra-luminous narrow-line regions (NLRs) at redshifts z=0.2-0.6. With a space density of 4.4 per cubic…
Probing the Nuclear and Circumnuclear Activity of NGC1365 in the Infrared
A. Alonso-Herrero, M. Sanchez-Portal, C. Ramos Almeida +12
We present new far-infrared (70-500micron) Herschel PACS and SPIRE imaging observations as well as new mid-IR Gemini/T-ReCS imaging (8.7 and 18.3micron) and spectroscopy of the inn…
