Ammonia as a Temperature Tracer in the Ultraluminous Galaxy Merger Arp220
Juergen Ott, Christian Henkel, James A Braatz +1
(abridged) We present ATCA and GBT observations of ammonia (NH3) toward the ultraluminous infrared galaxy (ULIRG) merger Arp220. We detect the NH3 (1,1), (2,2), (3,3), (4,4), (5,5)…
Narrow-line Seyfert 1 galaxies: an amasing class of AGN
A. Tarchi, P. Castangia, A. Columbano +2
[Abridged] Narrow-line Seyfert 1 (NLS1) galaxies are a class of active galactic nuclei (AGN) that have all the properties of type 1 Seyfert galaxies but show peculiar characteristi…
Ammonia (J,K) = (1,1) to (4,4) and (6,6) inversion lines detected in the Seyfert 2 galaxy NGC 1068
Y. Ao, C. Henkel, J. A. Braatz +3
We present the detection of the ammonia (NH3) (J,K) = (1,1) to (4,4) and (6,6) inversion lines toward the prototypical Seyfert 2 galaxy NGC 1068, made with the Green Bank Telescope…
