The October 2022 flare in OJ 287 and the mass of its primary black hole
Mauri J. Valtonen, Staszek Zola, Manpreet Singh +21
The bright blazar OJ~287 has demonstrated a sequence of flares, which are well explained by a quasi-Keplerian orbit model. The flares are associated with the impact of the secondar…
A growth of early superhump: Multi color observation of the WZ Sge star TCP J23580961+5502508
Ryosuke Sazaki, Makoto Uemura, Tatsuya Nakaoka +1
We report optical and near-infrared photometry of a WZ Sge-type dwarf nova, TCP J23580961+5502508, during its 2022 superoutburst, obtained using the 1.5-m Kanata telescope. Our obs…
Tracking down the broadband polarimetric properties of PG 1553+113
Riccardo Middei, Svetlana G. Jorstad, Alan P. Marscher +78
We report on a nine-month monitoring campaign of the blazar PG 1553+113, relying on three observations carried out in 2025 with the Imaging X-ray Polarimetry Explorer (IXPE) and su…
X-ray Doppler tomography of Fe K emission in a low-mass X-ray binary 4U 1822-371 - a localized reflector at the accretion stream-disk overflow
N. Sameshima, M. Tsujimoto, M. Uemura
We present the X-ray Doppler tomography of the Fe K (6.4 keV) fluorescence line of the low-mass X-ray binary 4U 1822-371 obtained with XRISM. Eleven orbits of this short period…
