Discovery of CO Clouds Associated with the X-ray Jets of SS 433: Evidence for Shock-Cloud Interaction Enhancing Nonthermal X-ray Emission
Haruka Sakemi, Hidetoshi Sano, Yasuo Fukui +7
We report the first identification of molecular clumps directly associated with the re-brightening regions of the large-scale X-ray jets of SS 433, based on CO ( = 1--0)…
The first proper motion measurement of the acceleration regions in the large-scale jets of SS 433 powering the W50 nebula
Naomi Tsuji, Yoshiyuki Inoue, Dmitry Khangulyan +10
We report on new Chandra ACIS-I observations of the X-ray knots located in the western and eastern lobes of W50 associated with the parsec-scale jets of the Galactic microquasar SS…
X-ray Study on Propagation of Non-thermal Particles in Microquasar SS 433/W 50 Extended Jets
Kazuho Kayama, Takaaki Tanaka, Hiroyuki Uchida +5
SS 433, located at the center of the W 50 radio nebula, is a binary system that ejects jets oriented east-west with precessional motion. X-ray lobes, containing compact "knots" lab…
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…
Single Event Tolerance of X-ray SOI Pixel Sensors
Kouichi Hagino, Mitsuki Hayashida, Takayoshi Kohmura +19
We evaluate the single event tolerance of the X-ray silicon-on-insulator (SOI) pixel sensor named XRPIX, developed for the future X-ray astronomical satellite FORCE. In this work,…
Spatially resolved study of the SS 433/W50 west region with Chandra: X-ray structure and spectral variation of non-thermal emission
Kazuho Kayama, Takaaki Tanaka, Hiroyuki Uchida +6
The X-ray binary SS 433, embedded in the W50 nebula (or supernova remnant W50), shows bipolar jets that are ejected with mildly relativistic velocities, and extend toward the east…
X-ray Radiation Damage Effects on Double-SOI Pixel Detectors for the Future Astronomical Satellite "FORCE"
Masatoshi Kitajima, Kouichi Hagino, Takayoshi Kohmura +20
We have been developing the monolithic active pixel detector "XRPIX" onboard the future X-ray astronomical satellite "FORCE". XRPIX is composed of CMOS pixel circuits, SiO2 insulat…
