Discovery of the Free Precession in the Magnetar SGR 180620 with the ASCA GIS
Kazuo Makishima, Nagomi Uchida, Teruaki Enoto
Four X-ray data sets of the Soft Gamma Repeater SGR 1806-20, taken with the Gas Imaging Spectrometer (GIS) onboad ASCA, were analyzed. Three of them were acquired over 1993 October…
Further Evidence for the ~ 9 s Pulsation in LS 5039 from NuSTAR and ASCA
Kazuo Makishima, Nagomi Uchida, Hiroki Yoneda +2
The present study aims to reinforce the evidence for the ~9 s pulsation in the gamma-ray binary LS 5039, derived with a Suzaku observation in 2007 and that with NuSTAR in 2016 (Yon…
GRBAlpha: the smallest astrophysical space observatory -- Part 1: Detector design, system description and satellite operations
András Pál, Masanori Ohno, László Mészáros +42
Aims. Since launched on 2021 March 22, the 1U-sized CubeSat GRBAlpha operates and collects scientific data on high-energy transients, making it the smallest astrophysical space obs…
Early results from GRBAlpha and VZLUSAT-2
Jakub Ripa, Andras Pal, Masanori Ohno +37
We present the detector performance and early science results from GRBAlpha, a 1U CubeSat mission, which is a technological pathfinder to a future constellation of nanosatellites m…
Study of the Polarimetric Performance of a Si/CdTe Semiconductor Compton Camera for the Hitomi Satellite
Junichiro Katsuta, Ikumi Edahiro, Shin Watanabe +17
Gamma-ray polarization offers a unique probes into the geometry of the gamma-ray emission process in celestial objects. The Soft Gamma-ray Detector (SGD) onboard the X-ray observat…
