Pilot KaVA monitoring on the M87 jet: confirming the inner jet structure and superluminal motions at sub-pc scales
Kazuhiro Hada, Jong Ho Park, Motoki Kino +34
We report the initial results of our high-cadence monitoring program on the radio jet in the active galaxy M87, obtained by the KVN and VERA Array (KaVA) at 22 GHz. This is a pilot…
Super-resolution Full Polarimetric Imaging for Radio Interferometry with Sparse Modeling
Kazunori Akiyama, Shiro Ikeda, Mollie Pleau +9
We propose a new technique for radio interferometry to obtain super-resolution full polarization images in all four Stokes parameters using sparse modeling. The proposed technique…
Imaging the Schwarzschild-radius-scale Structure of M87 with the Event Horizon Telescope using Sparse Modeling
Kazunori Akiyama, Kazuki Kuramochi, Shiro Ikeda +10
We propose a new imaging technique for radio and optical/infrared interferometry. The proposed technique reconstructs the image from the visibility amplitude and closure phase, whi…
