Unravelling Turbulence and Magnetic Fields in Galaxy Clusters with SKA and XRISM

Kohei Kurahara, Takuya Akahori, Amit Seta +5

This chapter proposes a research framework to quantitatively investigate non-thermal components in the Intracluster Medium (ICM) of galaxy clusters, which are critical ingredients…

Helical radio jets as probes of magnetised cluster environments: Periodic Faraday Rotation Revealed in the Corkscrew Galaxy by POSSUM

Sarah N. Bradbury, C. S. Anderson, N. M. McClure-Griffiths +14

Jets from active galactic nuclei (AGN) that exhibit regular plane-of-sky oscillations may provide a probe of magnetised plasma within the jets and their local intracluster medium (…

Origin and Evolution of the Structure in the Head-Tail Radio Galaxy of Abell 3322

Kohei Kurahara, Takuya Akahori, Takumi Ohmura +8

A head-tail galaxy is thought to be a radio galaxy with bent active galactic nuclei (AGN) jets interacting with the intracluster medium (ICM). Study of head-tail galaxies provides…

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…

A new window into the sub-parsec scale magnetic field in the Milky Way? Unveiling small-scale magneto-ionic structures with Faraday complexity

Yik Ki Ma, Amit Seta, N. M. McClure-Griffiths +9

Radio broadband spectro-polarimetric observations are sensitive to the spatial fluctuations of the Faraday depth (FD) within the telescope beam. Such FD fluctuations are referred t…

ALMA observations of the gamma-ray binary system PSR B1259-63/LS 2883 during the 2024 periastron passage

Yutaka Fujita, Akiko Kawachi, Atsuo T. Okazaki +3

We present observations of the gamma-ray binary PSR B1259-63/LS 2883 with the Atacama Large Millimeter/submillimeter Array (ALMA) at Bands 3 (97 GHz), 6 (233 GHz), and 7 (343 GHz).…
