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…
