Discovery of 40.5 ks Hard X-ray Pulse-Phase Modulations from SGR 1900+14
K. Makishima, T. Tamba, Y. Aizawa +4
X-ray timing properties of the magnetar SGR 1900+14 were studied, using the data taken with Suzaku in 2009 and NuSTAR in 2016, for a time lapse of 114 ks and 242 ks, respectively.…
Tomographic Imaging by a Si/CdTe Compton Camera for In-111 and I-131 Radionuclides
Goro Yabu, Hiroki Yoneda, Tadashi Orita +5
Tomographic imaging with radionuclides commonly used in nuclear medicine, such as In (171 and 245 keV) and I (364 keV), is in high demand for medical applications a…
Reconstruction of multiple Compton scattering events in MeV gamma-ray Compton telescopes towards GRAMS: the physics-based probabilistic model
Hiroki Yoneda, Hirokazu Odaka, Yuto Ichinohe +19
Aimed at progress in mega-electron volt (MeV) gamma-ray astronomy, which has not yet been well-explored, Compton telescope missions with a variety of detector concepts have been pr…
Broad-Band High-Energy Emission of the Gamma-ray Binary System LS 5039: Spectral and Temporal Features using NuSTAR and Fermi Observations
Hiroki Yoneda, Dmitry Khangulyan, Teruaki Enoto +4
We report on detailed analysis of the hard X-ray and GeV gamma-ray spectra of LS 5039, one of the brightest gamma-ray binary system in the Galaxy. The NuSTAR observation covering i…
An application of a Si/CdTe Compton camera for the polarization measurement of hard x-rays from highly charged heavy ions
Yutaka Tsuzuki, Shin Watanabe, Shimpei Oishi +6
The methods to measure the polarization of the x-rays from highly charged heavy ions with a significantly higher accuracy than the existing technology is needed to explore relativi…
Cross-match between the latest Swift-BAT and Fermi-LAT catalogs
Naomi Tsuji, Hiroki Yoneda, Yoshiyuki Inoue +4
We report the results of a cross-match study between the hard X-ray and GeV gamma-ray catalogs, by making use of the latest 105-month Swift-BAT and 10-yr Fermi-LAT catalogs, respec…
A NuSTAR confirmation of the 36 ks hard X-ray pulse-phase modulation in the magnetar 1E 1547.05408
Kazuo Makishima, Teruaki Enoto, Hiroki Yoneda +1
This paper describes an analysis of the NuSTAR data of the fastest-rotating magnetar 1E 15475408, acquired in 2016 April for a time lapse of 151 ks. The source was detected with…
