Mass function of a young cluster in a low-metallicity environment. Sh 2-209
Chikako Yasui, Naoto Kobayashi, Masao Saito +2
We present deep near-infrared (NIR) imaging of Sh 2-209 (S209), a low-metallicity ( dex) HII region in the Galaxy. From the NIR images, combined with astrometr…
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…
Survey of near-infrared diffuse interstellar bands in and bands. I. Newly identified bands
Satoshi Hamano, Naoto Kobayashi, Hideyo Kawakita +12
We searched for diffuse interstellar bands (DIBs) in the 0.911.33 m region by analyzing the near-infrared (NIR) high-resolution ( and 28,000) spectra of 31 redden…
Fast optical flares from M dwarfs detected by a one-second-cadence survey with Tomo-e Gozen
Masataka Aizawa, Kojiro Kawana, Kazumi Kashiyama +18
We report a one-second-cadence wide-field survey for M-dwarf flares using the Tomo-e Gozen camera mounted on the Kiso Schmidt telescope. We detect 22 flares from M3-M5 dwarfs with…
Star Formation Activity Beyond the Outer Arm II: Distribution and Properties of Star Formation
Natsuko Izumi, Naoto Kobayashi, Chikako Yasui +3
The outer Galaxy beyond the Outer Arm represents a promising opportunity to study star formation in an environment vastly different from the solar neighborhood. In our previous stu…
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…
