Faraday Tomography with Sparse Modeling
Kazunori Akiyama, Takuya Akahori, Yoshimitsu Miyashita +4
Faraday tomography (or rotation measure synthesis) is a procedure to convert linear polarization spectra into the Faraday dispersion function, which provides us with unique informa…
Radio broadband visualization of global three-dimensional magneto-hydrodynamical simulations of spiral galaxies II. Faraday Depolarization from 100MHz to 10GHz
Mami Machida, Takuya Akahori, Kenji Nakamura +2
Observational study of galactic magnetic fields is limited by projected observables. Comparison with numerical simulations is helpful to understand the real structures, and observa…
Radio broadband visualization of global three-dimensional magneto-hydrodynamical simulations of spiral galaxies I. Faraday rotation at 8GHz
Mami Machida, Takuya Akahori, Kenji Nakamura Hiroyuki Nakanishi +1
Observational study of galactic magnetic fields is hampered by the fact that the observables only probe various projections of the magnetic fields. Comparison with numerical simula…
Cool core disturbed: Observational evidence for coexistence of sub-sonic sloshing gas and stripped shock-heated gas around the core of RX J1347.5-1145
Shutaro Ueda, Tetsu Kitayama, Masamune Oguri +13
RXJ1347.5-1145 (z = 0.451) is one of the most luminous X-ray galaxy clusters, which hosts a prominent cool core and exhibits a signature of a major merger. We present the first dir…
Optimum Frequency of Faraday Tomography to Explore the Inter-Galactic Magnetic Field in Filaments of Galaxies
Takuya Akahori, Shinsuke Ideguchi, Takahiro Aoki +3
Faraday tomography is thought to be a powerful tool to explore cosmic magnetic field. Broadband radio polarimetric data is essential to ensure the quality of Faraday tomography, bu…
Discovery of Kolmogorov-like Magnetic Energy Spectrum in Tycho's Supernova Remnant by Two-point Correlations of Synchrotron Intensity
Jiro Shimoda, Takuya Akahori, A. Lazarian +2
The spectral slope of the magnetic energy in supernova remnants (SNRs) can be obtained by analysis of spatial two-point correlation functions of synchrotron intensities. This metho…
SKA-Athena Synergy White Paper
R. Cassano, R. Fender, C. Ferrari +35
The Advanced Telescope for High Energy Astrophysics (Athena) is the X-ray observatory large mission selected by the European Space Agency (ESA), within its Cosmic Vision 2015-2025…
Magnetic Field Analysis of the Bow and Terminal Shock of the SS433 Jet
Haruka Sakemi, Mami Machida, Takuya Akahori +4
We report a polarization analysis of the eastern region of W50, observed with the Australia Telescope Compact Array (ATCA) at 1.4 - 3.0 GHz. In order to study the physical structur…
