Spectral Modeling of the Supersoft X-ray Source CAL87 based on Radiative Transfer Codes
Masahiro Tsujimoto, Misaki Mizumoto, Ken Ebisawa +2
Super Soft X-ray Sources (SSS) are white dwarf (WD) binaries that radiate almost entirely below 1~keV. Their X-ray spectra are often complex when viewed with the X-ray gratin…
Circumnuclear Multi-phase Gas in the Circinus Galaxy. V. The Origin of the X-Ray Polarization in the Circinus Galaxy
Atsushi Tanimoto, Keiichi Wada, Yuki Kudoh +3
The Imaging X-ray Polarimetry Explorer (IXPE) detected X-ray polarization in the nearest Seyfert 2 galaxy, the Circinus galaxy, for the first time. To reproduce the IXPE results, w…
X-ray polarisation properties of thermal-radiative disc winds in binary systems
Ryota Tomaru, Chris Done, Hirokazu Odaka
New X-ray polarisation results are challenging our understanding of the accretion flow geometry in black hole binary systems. Even spectra dominated by a standard disc can give une…
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…
Simulation-based spectral analysis of X-ray CCD data affected by photon pile-up
Tsubasa Tamba, Hirokazu Odaka, Aya Bamba +6
We have developed a simulation-based method of spectral analysis for pile-up affected data of X-ray CCDs without any loss of photon statistics. As effects of the photon pile-up app…
