Bright Metal-Poor Star Survey - I. Tomo-e Gozen narrow-band photometric survey and medium-resolution spectroscopic follow-up
Hiroko Okada, Takumi Iwasaki, Nozomu Tominaga +21
We present the Tomo-e Gozen Bright Metal-Poor Star Survey (TeMPS), a wide-area narrow-band photometric survey for bright metal-poor stars in the northern sky. The survey uses the T…
An optical transient candidate of 2-second duration captured by wide-field video observations
Noriaki Arima, Mamoru Doi, Shigeyuki Sako +14
Recent time-domain surveys have revealed rapid transients that evolve on timescales of days, expanding the transient population into the short-duration regime. The tr…
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…
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…
[N I] 10400/10410 Å Lines as Possible Disk Wind Tracers in a Young Intermediate-Mass Star
Haruki Katoh, Chikako Yasui, Yuji Ikeda +10
In this study, we performed high-resolution near-infrared (NIR) spectroscopy (R = 28,000; -1.35 m) with a high signal-to-noise ratio on HD 200775, a very young (${\sim…
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…
