ALMA reveals spatially-resolved properties of molecular gas in the host galaxy of FRB 20191001A at z = 0.2340

Itsuki Yamanaka, Bunyo Hatsukade, Fumi Egusa +5

We report the detection of the CO(2-1) emission line with a spatial resolution of 0.9 arcsec () from the host galaxy of the fast radio burst (FRB), FRB 20191001A…

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…

Follow-up survey for the binary black hole merger GW200224_222234 using Subaru/HSC and GTC/OSIRIS

Takayuki Ohgami, Josefa Becerra Gonzalez, Nozomu Tominaga +19

The LIGO/Virgo detected a gravitational wave (GW) event, named GW200224_222234 (a.k.a. S200224ca) and classified as a binary-black-hole coalescence, on February 24, 2020. Given its…

Video Observations of Tiny Near-Earth Objects with Tomo-e Gozen

Jin Beniyama, Shigeyuki Sako, Ryou Ohsawa +20

We report the results of video observations of tiny (diameter less than 100 m) near-Earth objects (NEOs) with Tomo-e Gozen on the Kiso 105 cm Schmidt telescope. A rotational period…

The Redshift and Metallicity of the Host Galaxy of Dark GRB 080325 at z=1.78

Tetsuya Hashimoto, Daniel A. Perley, Kouji Ohta +5

We present near-infrared spectroscopy of the host galaxy of dark GRB 080325 using Subaru/MOIRCS. The obtained spectrum provides a clear detection of H emission and marginal [NII…
