PESSTO the world’s leading classification engine
PESSTO’s science goals have been to study the extremes of the explosive populations being found in large numbers by the most efficient surveys that have ever run. An important part of running the survey is taking a spectrum as quickly as possible after a transient is found and also to release the data, classification, redshift and any important or unusual characteristics. We do this on a daily basis, and nearly always within 12hrs of the end of the Chilean night.
As of January 1, 2016 the Transient Name Server (TNS) has been the official IAU mechanism for reporting new astronomical transients such as supernova candidates. Hosted at the Weizmann Institute of Science, this is a continuation of the IAU naming scheme for supernovae which was handled by the Central Bureau for Astronomical Telegrams until the end of 2015, and has been approved as the official IAU naming scheme by the IAU Executive Committee from 1st January 2016.
The IAU TNS keeps track of all the supernova candidates posted publicly and all spectroscopic classifications. The statistics are available on this page, showing that in the first 9 months of 2016 PESSTO is the leading engine to classify supernovae and report the results promptly to the community. Our results always have a reduced spectrum publicly available on the same rapid timescale, released through WISeREP
