SUIM project: measuring the upper atmosphere from the ISS by observations of the CXB transmitted through the Earth rim
Kumiko K. Nobukawa, Ayaki Takeda, Satoru Katsuda +16
The upper atmosphere at the altitude of 60-110 km, the mesosphere and lower thermosphere (MLT), has the least observational data of all atmospheres due to the difficulties of in-si…
Evaluation of the X-ray SOI pixel detector with the on-chip ADC
Hiroumi Matsuhashi, Kouichi Hagino, Aya Bamba +16
XRPIX is the monolithic X-ray SOI (silicon-on-insulator) pixel detector, which has a time resolution better than 10 s as well as a high detection efficiency for X-rays above…
ISAI: Investigating Solar Axion by Iron-57
Tomonori Ikeda, Toshihiro Fujii, Takeshi Go Tsuru +9
The existence of the axion is a unique solution for the strong CP problem, and the axion is one of the most promising candidates of the dark matter. Investigating Solar Axion by Ir…
Discovery of Year-Scale Time Variability from Thermal X-ray Emission in Tycho's Supernova Remnant
Masamune Matsuda, Hiroyuki Uchida, Takaaki Tanaka +2
Mechanisms of particle heating are crucial to understanding the shock physics in supernova remnants (SNRs). However, there has been little information on time variabilities of ther…
Temporal and Spatial Variation of Synchrotron X-ray Stripes in Tycho's Supernova Remnant
Masamune Matsuda, Takaaki Tanaka, Hiroyuki Uchida +2
The synchrotron X-ray "stripes" discovered in Tycho's supernova remnant (SNR) have been attracting attention since they may be evidence for proton acceleration up to PeV. We analyz…
Time Variability of Nonthermal X-ray Stripes in Tycho's Supernova Remnant with Chandra
Tomoyuki Okuno, Takaaki Tanaka, Hiroyuki Uchida +4
Analyzing Chandra data of Tycho's supernova remnant (SNR) taken in 2000, 2003, 2007, 2009, and 2015, we search for time variable features of synchrotron X-rays in the southwestern…
