Wavelets and sparsity for Faraday tomography
Suchetha Cooray, Tsutomu T. Takeuchi, Shinsuke Ideguchi +3
Faraday tomography through broadband polarimetry can provide crucial information on magnetized astronomical objects, such as quasars, galaxies, or galaxy clusters. However, the lim…
An Iterative Reconstruction Algorithm for Faraday Tomography
Suchetha Cooray, Tsutomu T. Takeuchi, Takuya Akahori +4
Faraday tomography offers crucial information on the magnetized astronomical objects, such as quasars, galaxies, or galaxy clusters, by observing its magnetoionic media. The observ…
Faraday dispersion function of disk galaxies with axisymmetric global magnetic fields I
Haruya Eguchi, Masaki Suzuki, Yoshimitsu Miyashita +2
Faraday tomography is a novel method to probe 3-dimensional structure of magnetic fields of polarized radio sources. In this paper, we investigate Faraday dispersion function (FDF)…
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…
Performance test of QU-fitting in cosmic magnetism study
Yoshimitsu Miyashita, Shinsuke Ideguchi, Shouta Nakagawa +2
QU-fitting is a standard model-fitting method to reconstruct distribution of magnetic fields and polarized intensity along a line of sight (LOS) from an observed polarization spect…
Cosmic Magnetism in Centimeter and Meter Wavelength Radio Astronomy
Takuya Akahori, Hiroyuki Nakanishi, Yoshiaki Sofue +13
Magnetic field is ubiquitous in the Universe and it plays essential roles in various astrophysical phenomena, yet its real origin and evolution are poorly known. This article revie…
Performance test of RM CLEAN and its evaluation with chi-square value
Yoshimitsu Miyashita, Shinsuke Ideguchi, Keitaro Takahashi
RM CLEAN is a standard method to reconstruct the distribution of cosmic magnetic fields and polarized sources along the line of sight (LOS) from observed polarization spectrum. Thi…
