Magnetic Reconnection in Galaxy Clusters
Takuya Akahori, Kohei Kurahara, Shin-ya Nitta +4
Galaxy clusters contain an intra-cluster medium (ICM) with temperatures of tens of millions of Kelvin. Cosmological structure formation simulations show that this diffuse gas is he…
Discovery of CO Clouds Associated with the X-ray Jets of SS 433: Evidence for Shock-Cloud Interaction Enhancing Nonthermal X-ray Emission
Haruka Sakemi, Hidetoshi Sano, Yasuo Fukui +7
We report the first identification of molecular clumps directly associated with the re-brightening regions of the large-scale X-ray jets of SS 433, based on CO ( = 1--0)…
Anisotropic Thermal Conduction as a Driver of Jet Collimation and Magnetic Field Amplification on Cold Fronts
Nana Matsuno, Takaaki Yokoyama, Mami Machida
Galaxy clusters contain a hot, diffuse, and weakly magnetized plasma known as the intracluster medium (ICM). In this environment, how thermal conduction influences plasma dynamics…
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…
Simulations of two-temperature jets in galaxy clusters: I. Effect of jet magnetization on dynamics and electron heating
Takumi Ohmura, Mami Machida
Non-radiating protons in the radio lobes have an essential role to form the jet morphology which is shown by recent radio and X-ray observations. However, since protons and electro…
Simulations of two-temperature jets in galaxy clusters: II. X-ray property of forward shock
Takumi Ohmura, Mami Machida, Hiroki Akamatsu
Forward shocks by radio jets, driven into the intracluster medium, are one of the indicators that can be used to evaluate the power of the jet. Meanwhile high-angular-resolution X-…
