The Study of X-Ray Flux Variability of M87
Ryo Imazawa, Yasushi Fukazawa, Hiromitsu Takahashi
We searched for a short-term X-ray variability of the M87 core and jet from archival X-ray data with long exposure data taken by the Suzaku, Chandra, and NuSTAR telescopes. We foun…
A study of the accretion mechanisms of the High Mass X-ray Binary IGR J00370+6122
Nagomi Uchida, Hiromitsu Takahashi, Yasushi Fukazawa +1
IGR J00370+6122 is a high-mass X-ray binary, of which the primary is a B1 Ib star, whereas the companion is suggested to be a neutron star by the detection of 346-s pulsation in on…
Detailed Design of the Science Operations for the XRISM mission
Yukikatsu Terada, Matt Holland, Michael Loewenstein +36
XRISM is an X-ray astronomical mission by the JAXA, NASA, ESA and other international participants, that is planned for launch in 2022 (Japanese fiscal year), to quickly restore hi…
Simulations of expected signal and background of gamma-ray sources by large field-of-view detectors aboard CubeSats
Gábor Galgóczi, Jakub Řípa, Riccardo Campana +19
In recent years the number of CubeSats (U-class spacecrafts) launched into space has increased exponentially marking the dawn of the nanosatellite technology. In general these sate…
The simulation framework of the timing-based localization for future all-sky gamma-ray observations with a fleet of Cubesats
Masanori Ohno, Norbert Werner, Andras Pal +22
The timing-based localization, which utilize the triangulation principle with the different arrival time of gamma-ray photons, with a fleet of Cubesats is a unique and powerful sol…
Origin of the in-orbit instrumental background of the Hard X-ray Imager onboard Hitomi
Kouichi Hagino, Hirokazu Odaka, Goro Sato +43
Understanding and reducing the in-orbit instrumental backgrounds are essential to achieving high sensitivity in hard X-ray astronomical observations. The observational data of the…
