Title: Rapid Spectroscopy of Elusive Transients and Young Supernovae

Abstract: The Palomar Transient Factory (PTF) is an ongoing synoptic survey designed with the eponymous goal of a systematic exploration of the transient sky and a clear appreciation that follow-up is as important as discovery. We have discovered and spectroscopically classified over 1450 supernovae and written over 42 papers. Our previous Gemini-PTF program successfully obtained the crucial first spectrum of multiple transients that bridge the six-magnitude luminosity gap between the brightest novae and faintest supernovae. We also obtained very early spectra of supernovae caught in their infancy. Going forward, PTF is moving to even faster cadence in search of even more ephemeral transients and young supernovae. Therefore, rapid response spectroscopy would be essential in identifying elusive transients and dictate a timely multi-wavelength follow-up campaign. Here, we request a total of eight target-of-opportunity triggers on the Gemini-South and Gemini-North telescopes (9.5 hours). We have ongoing programs for complementary follow-up: optical/NIR with Palomar/Magellan/Keck, UV/X-ray with the Swift satellite and radio with JVLA/CARMA.
