Spectral and photometric variability of SS 433 observed with XRISM and simultaneous optical and near-infrared telescopes
Yusuke Sakai, Shinya Yamada, Yuta Okada +36
We present results from coordinated multiwavelength observations of the SS 433, obtained with XRISM, optical telescopes, and near-infrared camera during 2024 April and 2025 March.…
Three-Dimensional Polarimetric Structure of Jets from Radio Galaxy MRC 0600-399 in A3376
Haruka Sakemi, James O. Chibueze, William D. Cotton +8
MRC 0600-399, in the merging galaxy cluster Abell 3376, is one of the unique Head-Tail radio galaxies having abruptly bending structures, the origin of which is still under discuss…
Arcsecond-Scale X-ray Imaging and Spectroscopy of SS 433 with Chandra HETG
Yusuke Sakai, Shinya Yamada, Haruka Sakemi +5
We present a spatial and spectral analysis of arcsecond-scale X-ray emission in SS 433 using zeroth-order data from Chandra High-Energy Transmission Grating (HETG) observations. Th…
Polarized X-rays Correlated with Short--Timescale Variability of Cygnus X-1
Kaito Ninoyu, Yuusuke Uchida, Shinya Yamada +4
We systematically investigate the variability of polarized X-rays on a timescale of a few seconds in the low/hard state of the black hole binary Cygnus X-1. The correlation between…
Radiation MHD Simulations of Soft X-ray Emitting Regions in Changing Look AGN
Taichi Igarashi, Hiroyuki R. Takahashi, Tomohisa Kawashima +3
Strong soft X-ray emission called soft X-ray excess is often observed in luminous active galactic nuclei (AGN). It has been suggested that the soft X-rays are emitted from a warm (…
