Abstract
The venerable study of cosmic explosions is over a century old. However, until recently, there has existed a glaring six-magnitude luminosity gap between the brightest novae and faintest supernovae. To find optical transients that are fainter, faster, and rarer than supernovae, we designed a systematic search: the Palomar Transient Factory. Theorists predict a variety of mechanisms to produce transients in the gap and observers have the best chance of finding them in the local universe. Here I present discoveries and unique physics of cosmic explosions that bridge this gap between novae and supernovae.

The Palomar Transient Factory is a fully-automated, wide-field survey aimed at a systematic exploration of explosions and variable phenomena in optical wavelengths. The program is centered on a 12Kx8K, 7.8 square degree CCD array (CFH12K) re-engineered for the 1.2-m Oschin Telescope at the Palomar Observatory by Caltech Optical Observatories. Photometric follow-up is undertaken by the automated Palomar 1.5-m telescope and other telescopes provided by consortium members including UC Berkeley, Weizman Institute, Israel, LCOGT and University of Oxford.
