Spectrum and location of ongoing extreme particle acceleration in Cassiopeia A
Jooyun Woo, Kaya Mori, Charles J. Hailey +8
Young supernova remnants (SNRs) are believed to be the origin of energetic cosmic rays (CRs) below the "knee" of their spectrum at petaelectronvolt (PeV, eV). Nev…
Imaging reconstruction method on X-ray data of CMOS polarimeter combined with coded aperture
Tsubasa Tamba, Hirokazu Odaka, Taihei Watanabe +7
X-ray polarization is a powerful tool for unveiling the anisotropic characteristics of high-energy celestial objects. We present a novel imaging reconstruction method designed for…
Multi-epoch X-ray spectral analysis of Centaurus A: revealing new constraints on iron emission line origins
Toshiya Iwata, Atsushi Tanimoto, Hirokazu Odaka +3
We conduct X-ray reverberation mapping and spectral analysis of the radio galaxy Centaurus A to uncover its central structure. We compare the light curve of the hard X-ray continuu…
Development of the X-ray polarimeter using CMOS imager: polarization sensitivity of a pixel CMOS sensor
Toshiya Iwata, Kouichi Hagino, Hirokazu Odaka +10
We are developing an imaging polarimeter by combining a fine-pixel CMOS image sensor with a coded aperture mask as part of the cipher project, aiming to achieve X-ray polarimetry i…
On the X-ray efficiency of the white dwarf pulsar candidate ZTF J190132.9+145808.7
Aya Bamba, Yukikatsu Terada, Kazumi Kashiyama +3
Strongly magnetized, rapidly rotating massive white dwarfs (WDs) emerge as potential outcomes of double degenerate mergers. These WDs can act as sources of non-thermal emission and…
