Optical Variability of Blazars in the Tomo-e Gozen Northern Sky Transient Survey

TianFang Zhang, Mamoru Doi, Mitsuru Kokubo +14

We studied the optical variability of 241 BL Lacs and 83 flat-spectrum radio quasars (FSRQ) from the 4LAC catalog using data from the Tomo-e Gozen Northern Sky Transient Survey, wi…

Intermediate-luminosity Type IIP SN 2021gmj: a low-energy explosion with signatures of circumstellar material

Yuta Murai, Masaomi Tanaka, Miho Kawabata +28

We present photometric, spectroscopic and polarimetric observations of the intermediate-luminosity Type IIP supernova (SN) 2021gmj from 1 to 386 days after the explosion. The peak…

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…

Deep simultaneous limits on optical emission from FRB 20190520B by 24.4 fps observations with Tomo-e Gozen

Yuu Niino, Mamoru Doi, Shigeyuki Sako +16

We conduct 24.4~fps optical observations of repeating Fast Radio Burst (FRB) 20190520B using Tomo-e Gozen, a high-speed CMOS camera mounted on the Kiso 105-cm Schmidt telescope, si…

Discovery of the Fastest Early Optical Emission from Overluminous SN Ia 2020hvf: A Thermonuclear Explosion within a Dense Circumstellar Environment

Ji-an Jiang, Keiichi Maeda, Miho Kawabata +28

In this Letter we report a discovery of a prominent flash of a peculiar overluminous Type Ia supernova, SN 2020hvf, in about 5 hours of the supernova explosion by the first wide-fi…
