The Sardinia Radio Telescope: From a Technological Project to a Radio Observatory
I. Prandoni, M. Murgia, A. Tarchi +43
[Abridged] The Sardinia Radio Telescope (SRT) is the new 64-m dish operated by INAF (Italy). Its active surface will allow us to observe at frequencies of up to 116 GHz. At the mom…
Water masers in Compton-thick AGN I. Detailed study of the new water megamaser in IRAS15480-0344
P. Castangia, A. Tarchi, A. Caccianiga +2
A relationship between the water maser detection rate and large nuclear column densities in AGN has often been cited in the literature. Indeed, detailed studies of luminous water m…
New Compton-thick AGN in the circumnuclear water maser hosts UGC3 789 and NGC 6264
P. Castangia, F. Panessa, C. Henkel +2
Large column densities, derived from X-ray studies, are typically measured towards AGN hosting water masers, especially when the H2O emission is associated with the nuclear accreti…
Long term Arecibo monitoring of the water megamaser in MG J0414+0534
P. Castangia, M. C. V. Impellizzeri, J. P. McKean +4
We monitored the 22 GHz maser line in the lensed quasar MG J0414+0534 at z=2.64 with the 300-m Arecibo telescope for almost two years to detect possible additional maser components…
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…
New H2O masers in Seyfert and FIR bright galaxies. III. The Southern Sample
G. Surcis, A. Tarchi, C. Henkel +3
Recently, a relationship between the water maser detection rate and far infrared (FIR) flux densities has been established as a result of two 22 GHz maser surveys in a complete sam…
