Second-timescale Glints from Satellites and Space Debris Detected with Tomo-e Gozen
Masaomi Tanaka, Ichiro Takahashi, Naoki Yoshida +17
A search for second-timescale optical transients is one of the frontiers of time-domain astronomy. However, it has been pointed out that reflections of sunlight from Earth-orbiting…

A systematic search for rapid transients in the Subaru HSC-SSP transient survey
Seiji Toshikage, Masaomi Tanaka, Naoki Yasuda +9
Recent high-cadence transient surveys have discovered rapid transients whose light curve timescales are shorter than those of typical supernovae. In this paper, we present a system…

A search for extragalactic fast optical transients in the Tomo-e Gozen high-cadence survey
Kakeru Oshikiri, Masaomi Tanaka, Nozomu Tominaga +15
The population of optical transients evolving within a time-scale of a few hours or a day (so-called fast optical transients, FOTs) has recently been debated extensively. In partic…
