Fast Transient Studies with Deep/High-cadence Time-domain Surveys
speaker: Jian Jiang
Abstract:
Transients with fast brightness variance in UV/optical wavelengths (”fast transients,” such as early-phase supernovae, fast blue optical transients, kilonovae) are of great interest in time-domain astronomy. Although great progresses in time-domain astronomy have been made via wide, shallow, and day(s)-cadence surveys, the limited observing depth and low time resolution make traditional time-domain surveys hard for fast-transient studies. In this talk, I will focus on our previous/ongoing studies of early-phase supernovae and fast blue optical transients via deep (Subaru/HSC) and high-cadence (Kiso/Tomo-e) wide-field surveys. As one of the most powerful time-domain survey facilities in the 2020s, I will also briefly talk about the upcoming Chinese 2.5m Wide-field Survey Telescope (WFST) project.
