Origin of the stellar Fe Kα line clarified with FUV and X-ray observations of a superflare on the RS Canum Venaticorum-type Star UX Arietis
Shun Inoue, Wataru Buz Iwakiri, Tomoki Kimura +11
Fluorescence line diagnostics of the Fe Kα line at keV observed in both solar and stellar flares can constrain the latitude and size of the flare loop, even in the absen…
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…
In-orbit Performance of the Soft X-ray Imaging Telescope Xtend aboard XRISM
Hiroyuki Uchida, Koji Mori, Hiroshi Tomida +62
We present a summary of the in-orbit performance of the soft X-ray imaging telescope Xtend onboard the XRISM mission, based on in-flight observation data, including first-light cel…
New CCD Driving Technique to Suppress Anomalous Charge Intrusion from Outside the Imaging Area for Soft X-ray Imager of Xtend onboard XRISM
Hirofumi Noda, Mio Aoyagi, Koji Mori +22
The Soft X-ray Imager (SXI) is an X-ray CCD camera of the Xtend system onboard the X-Ray Imaging and Spectroscopy Mission (XRISM), which was successfully launched on September 7, 2…
Soft X-ray Imager of the Xtend system onboard XRISM
Hirofumi Noda, Koji Mori, Hiroshi Tomida +57
The Soft X-ray Imager (SXI) is the X-ray charge-coupled device (CCD) camera for the soft X-ray imaging telescope Xtend installed on the X-ray Imaging and Spectroscopy Mission (XRIS…
Detection of extended X-ray emission around the PeVatron microquasar V4641 Sgr with XRISM
Hiromasa Suzuki, Naomi Tsuji, Yoshiaki Kanemaru +26
A recent report on the detection of very-high-energy gamma rays from V4641 Sagittarii (V4641 Sgr) up to ~0.8 peta-electronvolt has made it the second confirmed "PeVatron" microquas…
