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…
Rapidly Decaying Supernova 2010X: A Candidate ".Ia" Explosion
Mansi M. Kasliwal, S. R. Kulkarni, Avishay Gal-Yam +33
We present the discovery, photometric and spectroscopic follow-up observations of SN 2010X (PTF 10bhp). This supernova decays exponentially with tau_d=5 days, and rivals the curren…
PTF10fqs: A Luminous Red Nova in the Spiral Galaxy Messier 99
Mansi M. Kasliwal, S. R. Kulkarni, Iair Arcavi +38
The Palomar Transient Factory (PTF) is systematically charting the optical transient and variable sky. A primary science driver of PTF is building a complete inventory of transient…
Core-Collapse Supernovae from the Palomar Transient Factory: Indications for a Different Population in Dwarf Galaxies
Iair Arcavi, Avishay Gal-Yam, Mansi M. Kasliwal +26
We use the first compilation of 72 core-collapse supernovae (SNe) from the Palomar Transient Factory (PTF) to study their observed subtype distribution in dwarf galaxies compared t…
Hydrogen-poor superluminous stellar explosions
R. M. Quimby, S. R. Kulkarni, M. M. Kasliwal +24
Supernovae (SNe) are stellar explosions driven by gravitational or thermonuclear energy, observed as electromagnetic radiation emitted over weeks or more. In all known SNe, this ra…
