Boosting Water Maser Studies in AGN with the SKA
Andrea Tarchi, Paola Castangia, Elisabetta Ladu
Extragalactic water maser sources are unique tools to derive fundamental physical quantities of the host galaxies. In nearby and distant active galactic nuclei (AGN), water masers…

Detection of maser emission at 183 and 380 GHz with ALMA in the gigamaser galaxy TXS2226-184
A. Tarchi, P. Castangia, G. Surcis +3
Abridged. The LINER galaxy TXS2226-184 is known to host a very luminous 22 GHz water maser, called a gigamaser at the time of its discovery. To date, the nature of this maser is st…

IC 485:a new candidate disk-maser galaxy at 100 Mpc distance. Milliarcsecond resolution study of the galaxy nucleus and of the megamaser
E. Ladu, A. Tarchi, P. Castangia +4
Masers are a unique tool to investigate the emitting gas in the innermost regions of AGNs and to map accretion disks and tori orbiting around supermassive black holes. IC485, which…
