Padova-Asiago Supernova Group
The NOT Unbiased Transient Survey (NUTS)

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).
