Spectrophotometric accuracy of spectra obtained from spectroscopic plates measured with a commercial flatbed scanner
Kenshi Yanagisawa, Reiko Furusho, Shiomi Nemoto +3
The intensity spectra recovered from the spectroscopic photographic plates were compared with the CCD spectra, and we found the difference between the two was 2.5%.The measurements…
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…
The Thirty Millimeter Telescope
Yoshifusa Ita, Takashi Ichikawa, Hironori Tsutsui +11
A near-infrared telescope with an effective aperture diameter of thirty millimeters has been developed. The primary objective of the development is to observe northern bright stars…
J-GEM optical and near-infrared follow-up of gravitational wave events during LIGO's and Virgo's third observing run
Mahito Sasada, Yousuke Utsumi, Ryosuke Itoh +68
The Laser Interferometer Gravitational-wave Observatory Scientific Collaboration and Virgo Collaboration (LVC) sent out 56 gravitational-wave (GW) notices during the third observin…
Optical follow-up observation for GW event S190510g using Subaru/Hyper Suprime-Cam
Takayuki Ohgami, Nozomu Tominaga, Yousuke Utsumi +13
A gravitational wave event, S190510g, which was classified as a binary-neutron-star coalescence at the time of preliminary alert, was detected by LIGO/Virgo collaboration on May 10…
Long-Term Near-Infrared Brightening of Non-Variable OH/IR Stars
Takafumi Kamizuka, Yoshikazu Nakada, Kenshi Yanagisawa +8
Non-variable OH/IR stars are thought to have just left the asymptotic giant branch (AGB) phase. In this conventional picture, they must still show strong circumstellar extinction c…
