Padova-Asiago Supernova Group

The Asiago Transient Classification Program

Presentation
The program started in 2011 with the aim to classify all transients that are accessible from Asiago and are bright enough for our telescope/instrumentation. We use mainly the 1.82m Copernico telescope of Cima Ekar and, if not available, the 1.22m Galileo telescope of the Pennar station. A few cases of transients classified by our group with other facilities (eg. TNG) are included in the database.
Transient classification information and spectra (fits format) are made immediately available at our site. The spectra are semi-automatic reduction with archive calibration data. Please keep this in mind when using them.
For SN classification we compare the output of two automatic SN classification codes: Gelato (Harutyunyan et al. 2008, A&A 488, 383) and SNID (Blondin and Tonry 2007, Ap.J. 666, 1024).
If you use some of the information posted in these pages please make a reference to the paper Tomasella etal. 2014, A.N. 335, 841.

2020fkb in Arp 299

2020fkb in Arp 299
Discovered by: ALeRCE ZTF

The Asiago Transient Classification Program (Tomasella et al. 2014, AN, 335, 841) reports the spectroscopic observation of ZTF18aarlpzd (AT 2020fkb) in Arp 299.

The target was supplied by ZTF, discovered by ALeRCE using the public ZTF stream.

The observation was performed with the Asiago 1.82m Copernico Telescope (+ AFOSC; range 340-820 nm; resolution 1.4 nm).

(1) The blue spectrum, although largely dominated by narrow emission line of the surrounding H II region, shares similarity with those of stripped-envelope SNe about 1 week before the maximum light.

The classification was performed using the GELATO (Harutyunyan et al. 2008, A&A, 488, 383).
