Calcium-rich gap transients in the remote outskirts of galaxies
Mansi M. Kasliwal, S. R. Kulkarni, Avishay Gal-Yam +25
From the first two seasons of the Palomar Transient Factory, we identify three peculiar transients (PTF09dav, PTF10iuv, PTF11bij) with five distinguishing characteristics: peak lum…
SN2010jp (PTF10aaxi): A Jet-Driven Type II Supernova
Nathan Smith, S. Bradley Cenko, Nat Butler +18
We present photometry and spectroscopy of the peculiar TypeII supernova (SN) 2010jp, also named PTF10aaxi. The light curve exhibits a linear decline with a relatively low peak abso…
An extremely luminous panchromatic outburst from the nucleus of a distant galaxy
A. J. Levan, N. R. Tanvir, S. B. Cenko +58
Variable X-ray and gamma-ray emission is characteristic of the most extreme physical processes in the Universe, and studying the sources of these energetic photons has been a major…
PTF10iya: A short-lived, luminous flare from the nuclear region of a star-forming galaxy
S. Bradley Cenko, Joshua S. Bloom, S. R. Kulkarni +28
We present the discovery and characterisation of PTF10iya, a short-lived (dt ~ 10 d, with an optical decay rate of ~ 0.3 mag per d), luminous (M_g ~ -21 mag) transient source found…
Supernova PTF 09uj: A possible shock breakout from a dense circumstellar wind
E. O. Ofek, I. Rabinak, J. D. Neill +29
Type-IIn supernovae (SNe), which are characterized by strong interaction of their ejecta with the surrounding circumstellar matter (CSM), provide a unique opportunity to study the…
