Our group is one of the leading nodes of NUTS (the extension of the program is known as
NUTS2), which is a long-term
observational follow-up programme led by researchers from Denmark,
Finland, Ireland, Italy, Spain and Sweden to study peculiar transients
in the optical
and near-infrared domains. We aim at studying 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).
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. 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 (with the New Technology Telescope, the Las Cumbres Observatories Global Telescope network, PROMPT and REM). Additional data are offered through international collaborations such as the SupernovaExchange(2.) collaboration based on data collected with the
Las Cumbres Observatory Global Telescope (LCOGT) network.
NUTS/NUTS2 was a 3-years project initiated in Spring 2016, and has been later extended up to reach the current 10 years of life.
It is currently awarded by about 50 hours per semester in
ToO mode, and 12 half-nights per semester in service (queuing) mode.
