Padova-Asiago Supernova Group
The OAPD Supernova Group activity in PESSTO

The Public ESO Spectroscopic Survey for Transient Objects (PESSTO; PI; S. J. Smartt), is one of the two Public Spectroscopic Surveys currently running at ESO.
The survey has been awarded with 90 nights/year (for a total of 4 yr) at the New Technology Telescope of ESO - La Silla to classify about 2000 transients over its entire lifetime, and to monitor in detail about 150 transients selected among those matching the PESSTO target selection criteria. Appealing targets for PESSTO are: unusual transient, nearby supernovae suitable for detailed progenitor studies, normal supernovae in unusual environments (low-metallicity galaxies, remote locations in giant galaxies, interacting galaxy systems, dusty environments).

The first PESSTO data release (DR1) is now publicly available from the ESO archive search and retrieve interface.
Additional information can be found on the PESSTO Wiki pages.


PESSTO is organized in several operational teams, each one with specific tasks aimed to the survey management. PIs of the team may rotate during the survey lifetime, and former and/or current Padova reseachers have had a leadership role in many of these.


To study in detail interesting new transients, the almost 100 scientists that joined PESSTO formed 15 science teams, each of them with specific science focus. In particular, the Padova team has leadership in the following topics:
  • Statistical analysis of PESSTO classifications: PI E. Cappellaro
  • Extincted/reddened Supernovae: PI N. Elias-Rosa
  • Weak Type II-plateau Supernovae: PI M. Turatto
  • The extremes of interacting core-collapse Supernovae (including SN impostors, Type IIn SNe, Type Ibn SNe): PI at rotation, currently R. Kotak (QUB), the former was S. Benetti
