Unveiling the central parsec region of an active galactic nucleus: The circinus nucleus in the near-infrared with the very large telescope by Almudhna Prieto, M, Meisenheimer, K, Marco, O, Reunanen, J, Contini, M, Clenet, Y, Davies, R, Gratadour, D, Henning, T, Klaas, U, Kotitanien, J, Leinert, C, Lutz, D, Rouan, D, Thatte, N

“…Hotter dust within a 1 pc radius of the center is not detected. The active galactic nucleus (AGN) luminosity required to heat this dust is in the range of X-ray luminosities that have been measured toward the central source. …”

Galaxies: The short wavelength view by Lutz, D, Genzel, R, Sturm, E, Rigopoulou, D, Tran, D, Moorwood, A, Spoon, H, Forster-Schreiber, N, Thornley, M, Alexander, T, Sternberg, A

“…They are absent close to an active galactic nucleus but can be strong on larger scales of the AGN host, in particular if there is intense circumnuclear star formation. …”

Obscured activity: AGN, quasars, starbursts and uligs observed by the infrared space observatory by Verma, A, Lutz, D, Charmandaris, V, Klaas, U, Haas, M

“…ISO surveyed a wide range of active galaxies which, in the context of this review, includes those powered by intense bursts of star formation as well as those containing a dominant active galactic nucleus (AGN). Mid-infrared imaging resolved for the first time the dust enshrouded nuclei in many nearby galaxies, while a new era in infrared spectroscopy was opened by probing a wealth of atomic, ionic and molecular lines as well as broad band features in the mid-and farinfrared. …”

FAST MOLECULAR OUTFLOWS IN LUMINOUS GALAXY MERGERS: EVIDENCE FOR QUASAR FEEDBACK FROM HERSCHEL by Veilleux, S, Melendez, M, Sturm, E, Gracia-Carpio, J, Fischer, J, Gonzalez-Alfonso, E, Contursi, A, Lutz, D, Poglitsch, A, Davies, R, Genzel, R, Tacconi, L, de Jong, J, Sternberg, A, Netzer, H, Hailey-Dunsheath, S, Verma, A, Rupke, D, Maiolino, R, Teng, S, Polisensky, E

“…While the outflow velocities show no statistically significant dependence on the star formation rate, they are distinctly more blueshifted among systems with large active galactic nucleus (AGN) fractions and luminosities [log (L AGN/L⊙) ≥ 11.8 ± 0.3]. …”

Excited OH+, H2O+, and H3O+ in NGC 4418 and Arp 220 by Gonzalez-Alfonso, E, Fischer, J, Bruderer, S, Mueller, H, Gracia-Carpio, J, Sturm, E, Lutz, D, Poglitsch, A, Feuchtgruber, H, Veilleux, S, Contursi, A, Sternberg, A, Hailey-Dunsheath, S, Verma, A, Christopher, N, Davies, R, Genzel, R, Tacconi, L

“…In NGC 4418, we argue that X-ray ionization due to an active galactic nucleus is responsible for the molecular ion production. © 2013 ESO.…”

HERSCHEL-PACS OBSERVATIONS OF FAR-IR CO LINE EMISSION IN NGC 1068: HIGHLY EXCITED MOLECULAR GAS IN THE CIRCUMNUCLEAR DISK by Hailey-Dunsheath, S, Sturm, E, Fischer, J, Sternberg, A, Gracia-Carpio, J, Davies, R, Gonzalez-Alfonso, E, Mark, D, Poglitsch, A, Contursi, A, Genzel, R, Lutz, D, Tacconi, L, Veilleux, S, Verma, A, de Jong, J

“…The blueshift of the HE lines may also be consistent with the bluest regions of this H2 ring, but a better kinematic match is found with a clump of infalling gas 40pc north of the active galactic nucleus (AGN). We consider potential heating mechanisms and conclude that X-ray- or shock heating of both components is viable, while far-UV heating is unlikely. …”
