Title: Transients in the Local Universe
Abstract:
Spectroscopic follow-up gives the the most crucial data necessary to decipher
the true nature of a transient. A spectrum can help unambiguously identify a
transient by revealing its distance, physical state and composition. We have
undertaken a systematic search of optical transients in the glaring
luminosity gap between novae and supernovae with the Palomar Transient
Factory. This survey systematically targets local galaxy-light concentrations
over a large area in the sky and is unique in its depth and cadence. In
particular, taking exposures every night probes an unexplored phase space, in
which there are few empirical constraints but interesting theoretical
expectations for fast transients in the gap. A rapidly fading novel transient
warrants rapid follow-up. In turn, rapid follow-up helps plan the most
optimal multiwavelength campaign (Radio to X-ray). We propose for two
rapid-response target-of-opportunity triggers on the Gemini-South telescope.
