Observations of the Crab Nebula and Pulsar with the Large-Sized Telescope Prototype of the Cherenkov Telescope Array
CTA-LST Project, :, H. Abe +289
CTA (Cherenkov Telescope Array) is the next generation ground-based observatory for gamma-ray astronomy at very-high energies. The Large-Sized Telescope prototype (LST-1) is locate…
X-ray/H scaling relationships in stellar flares
Hiroki Kawai, Yohko Tsuboi, Wataru B. Iwakiri +5
We report on the results of our simultaneous observations of three large stellar flares with soft X-rays (SXRs) and an H emission line from two binary systems of RS CVn t…
ALMA ACA detection of submillimeter emission associated with the west hot spot of the radio galaxy Pictor A
Naoki Isobe, Hiroshi Nagai, Motoki Kino +4
In order to investigate the far-infrared excess detected from the west hot spot of the radio galaxy Pictor A with the Herschel observatory, a submillimeter photometry is performed…
Gravitational Redshift Detection from the Magnetic White Dwarf Harbored in RX J1712.6-2414
Takayuki Hayashi, Hideyuki Mori, Koji Mukai +2
Gravitational redshift is a fundamental parameter that allows us to determine the mass-to-radius ratio of compact stellar objects, such as black holes, neutron stars, and white dwa…
High-Resolution X-Ray Spectroscopy of Supernova Remnants
Satoru Katsuda
Thermal X-ray spectra from supernova remnants (SNRs) are dominated by a number of line emission from various elements. Resolving the individual lines is critically important for a…
eROSITA Final Equatorial-Depth Survey (eFEDS): eFEDS X-ray view of WERGS Radio Galaxies selected by the Subaru/HSC and VLA/FIRST survey
Kohei Ichikawa, Takuji Yamashita, Andrea Merloni +19
We construct the eROSITA X-ray catalog of radio galaxies discovered by the WERGS survey that is made by the cross-matching of the wide-area Subaru/HSC optical survey and VLA/FIRST…
Discovery of the luminous X-ray ignition eRASSt J234402.9352640; I. Tidal disruption event or a rapid increase in accretion in an active galactic nucleus?
D. Homan, M. Krumpe, A. Markowitz +17
In November 2020, a new, bright object, eRASSt J234402.9352640, was discovered in the second all-sky survey of SRG/eROSITA. The object brightened by a factor of at least 150 in…
Disc corona radii and QPO frequencies in black hole binaries: testing Lense-Thirring precession origin
Aya Kubota, Chris Done, Kazuki Tsurumi +1
Stellar-mass black hole binary systems in the luminous X-ray states show a strong quasi-periodic oscillation (QPO) in their Comptonised emission. The frequency of this feature corr…
A broad-line quasar with unexplained extreme velocity offsets: post-shock outflow?
V. Rusakov, C. L. Steinhardt, M. Schramm +4
The quasar SDSS 0956+5128 exhibits three distinct velocity components with large offsets in emission: the systemic velocity of [O II], [O III] and [Ne III] narrow lines have redshi…
