The short time domain (< 1 day) is the frontier of transient astronomy. In this frontier, new phenomena are waiting to be discovered that may hold the answers to crucial questions, particularly for progenitors of extreme events e.g., supernovae, gravitational waves/kilonovae, and GRBs. I will present the work from my thesis to develop GLUV, a high cadence UV survey telescope system, and a systematic search of Kepler/K2 data through the Background Survey for undiscovered transients. From the Background Survey I have detected numerous unknown transients serendipitously observed by Kepler. The First confirmed discovery is a WZ Sge type dwarf nova called KSN:BS-C11a, with a broken rise that indicates new physics in dwarf nova. The detection of a broken rise in KSN:BS-C11a was only possible with high cadence observations, and is indicative of future discoveries that will be made in the short time domain as we explore it with Kepler, TESS and GLUV. |
