Hard X-ray Spectral Investigations of Gamma-ray Bursts, 120521C and 130606A, at High-redshift z~6
Tetsuya Yasuda, Yuji Urata, Junich Enomoto +1
This study presents the temporal and spectral analysis of the prompt emission of two high-redshift gamma-ray bursts (GRBs), 120521C at and 130606A at , which we…
Two Distinct-Absorption X-Ray Components from Type IIn Supernovae: Evidence for Asphericity in the Circumstellar Medium
Satoru Katsuda, Keiichi Maeda, Aya Bamba +7
We present multi-epoch X-ray spectral observations of three Type IIn supernovae (SNe) 2005kd, 2006jd, and 2010jl, acquired with Chandra, XMM-Newton, Suzaku, and Swift. Previous ext…
Search for EeV Protons of Galactic Origin
R. U. Abbasi, M. Abe, T. Abu-Zayyad +126
Cosmic rays in the energy range - eV are thought to have a light, probably protonic, composition. To study their origin one can search for anisotropy in the…
Hitomi constraints on the 3.5 keV line in the Perseus galaxy cluster
Hitomi Collaboration, Felix A. Aharonian, Hiroki Akamatsu +215
High-resolution X-ray spectroscopy with Hitomi was expected to resolve the origin of the faint unidentified E=3.5 keV emission line reported in several low-resolution studies of va…
CALET Upper Limits on X-ray and Gamma-ray Counterparts of GW 151226
O. Adriani, Y. Akaike, K. Asano +89
We present upper limits in the hard X-ray and gamma-ray bands at the time of the LIGO gravitational-wave event GW 151226 derived from the CALorimetric Electron Telescope (CALET) ob…
Suzaku observations of the hard X-ray spectrum of Vela Jr
Sawako Takeda, Aya Bamba, Yukikatsu Terada +5
We report the results of Suzaku observations of the young supernova remnant, Vela Jr.\ (RX J0852.04622), which is known to emit synchrotron X-rays, as well as TeV gamma-rays. Ut…
Measurements of the Soft Gamma-ray Emission from SN2014J with Suzaku
Y. Terada, K. Maeda, Y. Fukazawa +9
The hard X-ray detector (HXD) onboard {\it Suzaku} measured soft -rays from the Type Ia supernova SN2014J at days after the explosion. Although the confidence level of…
Discovery of X-ray Emission from the Galactic Supernova Remnant G32.8-0.1 with Suzaku
Aya Bamba, Yukikatsu Terada, John Hewitt +6
We present the first dedicated X-ray study of the supernova remnant (SNR) G32.8-0.1 (Kes 78) with Suzaku. X-ray emission from the whole SNR shell has been detected for the first ti…
No Evidence of Intrinsic Optical/Near-Infrared Linear Polarization for V404 Cygni During its Bright Outburst in 2015: Broadband Modeling and Constraint on Jet Parameters
Y. T. Tanaka, R. Itoh, M. Uemura +39
We present simultaneous optical and near-infrared (NIR) polarimetric results for the black hole binary V404 Cygni spanning the duration of its 7-day long optically-brightest phase…
