Towards the Automation in the Space Station: Feasibility Study and Ground Tests of a Multi-Limbed Intra-Vehicular Robot
Seiko Piotr Yamaguchi, Kentaro Uno, Yasumaru Fujii +4
This paper presents a feasibility study, including simulations and prototype tests, on the autonomous operation of a multi-limbed intra-vehicular robot (mobile manipulator), shortl…
A systematic study on the aromatic and aliphatic hydrocarbon emission features of nearby galaxies using AKARI near-IR spectra
Tsubasa Kondo, Hidehiro Kaneda, Shinki Oyabu +7
Interstellar hydrocarbon dust containing aromatic and aliphatic hydrocarbons, like polycyclic aromatic hydrocarbons (PAHs), is believed to be processed by various factors including…
XRISM view of a stellar flare: High-resolution Fe K spectra of HR 1099, an RS CVn-type star
Miki Kurihara, Masahiro Tsujimoto, Michael Loewenstein +21
A high-resolution X-ray spectroscopic observation was made of the RS CVn-type binary star HR 1099 using the Resolve instrument onboard XRISM for its calibration purposes. During th…
Chemical composition and enrichment of the Centaurus cluster core seen by XRISM/Resolve
F. Mernier, K. Fukushima, A. Simionescu +16
Hot, X-ray emitting atmospheres pervading galaxy clusters are rich in metals, which have been synthesised and released by asymptotic giant branch (AGB) stars, core-collapse superno…
Delving into the depths of NGC 3783 with XRISM IV. Mapping of the accretion flow with Fe K emission lines
Chen Li, Jelle S. Kaastra, Liyi Gu +18
Using XRISM/Resolve time-averaged spectra of the well-known Seyfert-1.5 active galactic nucleus (AGN) in NGC 3783, we investigate the nature of the Fe K emission…
Delving into the depths of NGC 3783 with XRISM III. Birth of an ultrafast outflow during a soft flare
Liyi Gu, Keigo Fukumura, Jelle Kaastra +18
The 2024 X-ray/UV observation campaign of NGC 3783, led by XRISM, revealed the launch of an ultrafast outflow (UFO) with a radial velocity of 0.19c (57000 km/s). This event is sync…
