Optical and X-ray variations during 5 outbursts of Aql X-1 in 3.6 years from 2016
Masafumi Niwano, Katsuhiro L. Murata, Naohiro Ito +2
We analyzed optical/X-ray quasi-simultaneous light curves of Aql X-1, obtained by MAXI (Monitor of All-sky X-ray Image), ZTF (Zwicky Transient Facility) and LCO (Las Cumbres Observ…
GRB 221009A: Discovery of an Exceptionally Rare Nearby and Energetic Gamma-Ray Burst
Maia A. Williams, Jamie A. Kennea, S. Dichiara +53
We report the discovery of the unusually bright long-duration gamma-ray burst (GRB), GRB 221009A, as observed by the Neil Gehrels Swift Observatory (Swift), Monitor of All-sky X-ra…
Discovery of a new supergiant fast X-ray transient MAXI J0709-159 associated with the Be star LY CMa
Mutsumi Sugizaki, Tatehiro Mihara, Kohei Kobayashi +10
We report on the discovery of a new supergiant fast X-ray transient (SFXT), MAXI J0709159, and its identification with LY CMa (also known as HD 54786). On 2022 January 25, a new…
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…
Gravitational Wave Physics and Astronomy in the nascent era
Makoto Arimoto, Hideki Asada, Michael L. Cherry +50
The detections of gravitational waves (GW) by LIGO/Virgo collaborations provide various possibilities to physics and astronomy. We are quite sure that GW observations will develop…
The Peculiar X-ray Transient Swift J0840.7-3516: an Unusual Low Mass X-ray Binary or a Tidal Disruption Event?
Megumi Shidatsu, Wataru Iwakiri, Hitoshi Negoro +9
We report on the X-ray properties of the new transient Swift J0840.73516, discovered with Swift/BAT in 2020 February, using extensive data of Swift, MAXI, NICER, and NuSTAR. The…
