A Systematic Study of Quiescent and Outburst Properties of X-ray-bright Young Stellar Objects Using XMM-Newton
Koki Sakuta, Ikuyuki Mitsuishi, Seiya Sasamata +6
Young Stellar Objects (YSOs) exhibit strong X-ray emission, widely attributed to magnetic reconnection and magnetospheric accretion; however, owing primarily to limited photon stat…
XMM-Newton observations of ten high-redshift CAMIRA clusters of galaxies
Naomi Ota, Ikuyuki Mitsuishi, Nobuhiro Okabe +9
We present results from XMM-Newton observations of ten high-redshift () galaxy clusters selected from the CAMIRA catalog based on high richness (). These m…
Development of Electroformed X-ray Optics Bridging Synchrotron Technology and Space Astronomy
Ryuto Fujii, Koki Sakuta, Kazuki Ampuku +21
We have developed X-ray telescope mirrors using an original electroforming replication technique established through the fabrication of millimeter-aperture, ultra-short-focal-lengt…
X-ray emission of F-type stars and its analogy with G-type stars
Takuma Shimura, Ikuyuki Mitsuishi, Masanobu Kunitomo +3
We conducted a systematic spectral study for single F-type main-sequence (MS) stars without significant X-ray outbursts to investigate X-ray spectral properties such as temperature…
