Advancing extragalactic spectral line studies with the Square Kilometre Array Observatory
Jacco Th. van Loon, Viviana Casasola, Manuela Bischetti +6
We present an overview of the Square Kilometre Array Observatory (SKAO) science potential in the area of extragalactic spectral lines besides 21-cm neutral hydrogen. It highlights…
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…
Study of the thermal and nonthermal emission components in M31: the Sardinia Radio Telescope view at 6.6 GHz
S. Fatigoni, F. Radiconi, E. S. Battistelli +21
The Andromeda galaxy is the best-known large galaxy besides our own Milky Way. Several images and studies exist at all wavelengths from radio to hard X-ray. Nevertheless, only a fe…
The Radio Structure of the Narrow-Line Seyfert 1 Mrk 783 with VLBA and e-MERLIN
E. Congiu, P. Kharb, A. Tarchi +9
In this paper, we present the analysis of new radio and optical observations of the narrow-line Seyfert 1 galaxy Mrk 783. 1.6 GHz observations performed with the e-MERLIN interfero…
