PESSTO’s Serendipitous Supernova Discovery

For the first time PESSTO have discovered a supernova of their own! The supernova was discovered in UBVRI EFOSC imaging taken of galaxy ESO-154-G010, the host of the previous supernova SN2013fc, on the 16th November 2014. Tuomas Kangas (University of Turku) spotted the new transient while taking images for the PESSTO campaign on SN2013fc. The supernova is identified in the composite VRI colour-image below by the red cross-hairs and has been reported Smith et al. ATel 6739 . This is an excellent opportunity to study a young, peculiar SN from before maximum light to the nebular phase and ...

OGLE-2013-SN-079: a lonely supernova consistent with a helium shell detonation

OGLE-2013-SN-079: a lonely supernova consistent with a helium shell detonation, a new PESSTO paper by Inserra et al. is now available on arXiv.

We present observational data for a peculiar supernova discovered by the OGLE-IV survey and followed by the Public ESO Spectroscopic Survey for Transient Objects. The inferred redshift of z=0.07 implies an absolute magnitude in the rest-frame I-band of M_I~-17.6. This places it in the luminosity range between normal Type Ia SNe and novae. Optical and ...
