Our group is one of the leading nodes of
NUTS, which is a long-term
observational follow-up programme led by researchers from Denmark,
Finland, Ireland, Italy, Spain and Sweden to study peculiar optical
and near-infrared transients, including nearby supernovae and
and transients discovered
within hours to days after outburst by the main surveys, including
the All-Sky Automated Survey for Supernovae (ASAS-SN), the Asteroid
Terrestrial-impact Last Alert System (ATLAS), the Zwicky Transient Facility
(ZTF), the Panoramic Survey Telescope & Rapid Response System (Pan-STARRS),
and the Gravitational-Wave Optical Transient Observer (GOTO).
Particular interests is devoted to gap transients, and transients discovered in nuclear regions
of galaxies (supernovae, tidal-disruption
events, unpredicatble AGN behaviours; this is the Thesis subject of our MSci student Irene Salmaso).
We use the 2.56m Nordic Optical
Telescope (NOT) with ALFOSC and NOTCam for a rapid spectroscopic
classification and subsequent follow-up of these transient events. NUTS/NUTS2 targets are also supported
by complementary observations performed with the Asiago Observatory facilities, Telescopio Nazionale Galileo (TNG), Liverpool Telescope and The Gran Telescopio Canarias (GTC). Equatorial NUTS/NUTS2 targets are also followed by Southern facilities (the New Technology Telescope via PESSTO/ePESSTO+, PROMPT and REM).
NUTS was a 3-years project initiated in Spring 2016, and has been later extended by further 2 years (NUTS2). It has been awarded by about 70 hours per semester in ToO mode, and 12 half-nights per semester in service (queuing) mode (including Italian NOT-TNG exchange time, and Opticon time from the Irish team).
