In X-ray observations, estimation of the particle-induced background is
important especially for faint and/or diffuse sources. Although software exists
to generate total (sky and detector) background data suitable for a given
Chandra ACIS observat...
The age of a supernova remnant (SNR) is, though undoubtedly one of the most
important properties for study of its evolution, difficult to estimate reliably
in most cases. In this study, we compare the dynamical and plasma ages of the
SNRs and char...

We propose a novel concept of a ultracompact hard X-ray imaging polarimeter system that utilizes the combination of a fine-pixel CMOS imaging sensor and a narrow field-of-view coded aperture mask with multiple different random patterns. An instrum...

Supernova remnants (SNRs) are thought to be the most plausible sources of
Galactic cosmic rays. One of the principal questions is whether they are
accelerating particles up to the maximum energy of Galactic cosmic rays
(PeV). In this paper, ...
The evidence for multi-messenger photon and neutrino emission from the blazar
TXS 0506+056 has demonstrated the importance of realtime follow-up of neutrino
events by various ground- and space-based facilities. The effort of H.E.S.S.
and other exp...

IRAS 00500+6713 is a hypothesized remnant of a type Iax supernova SN 1181.
Multi-wavelength observations have revealed its complicated morphology; a dusty
infrared ring is sandwiched by the inner and outer X-ray nebulae. We analyze
the archival X-...

Xtend is a soft X-ray imaging telescope developed for the X-Ray Imaging and
Spectroscopy Mission (XRISM). XRISM is scheduled to be launched in the Japanese
fiscal year 2022. Xtend consists of the Soft X-ray Imager (SXI), an X-ray CCD
camera, and t...
