Three-dimensional X-ray observation of atmospheric biological samples by linear-array scanning-electron generation X-ray microscope system. [PDF]

open access: yesPLoS ONE, 2011
Recently, we developed a soft X-ray microscope called the scanning-electron generation X-ray microscope (SGXM), which consists of a simple X-ray detection system that detects X-rays emitted from the interaction between a scanning electron beam (EB) and ...

IRCM‐Caps: An X‐ray image detection method for COVID‐19

open access: yesThe Clinical Respiratory Journal, 2023
Objective COVID‐19 is ravaging the world, but traditional reverse transcription‐polymerase reaction (RT‐PCR) tests are time‐consuming and have a high false‐negative rate and lack of medical equipment.

First detection of phase-dependent colliding wind X-ray emission outside the Milky Way [PDF]

open access: yes, 2007
After having reported the detection of X-rays emitted by the peculiar system HD5980, we assess here the origin of this high-energy emission from additional X-ray observations obtained with XMM-Newton.

The z=5.8 Quasar SDSSp J1044-0125: A Peek at Quasar Evolution? [PDF]

open access: yes, 2001
The newly discovered z=5.8 quasar SDSSp J104433.04-012502.2 was recently detected in X-rays and found to be extremely X-ray weak. Here we present the hardness ratio analysis of the XMM-Newton observation.
