The ALMA Phasing System: A Beamforming Capability for Ultra-High-Resolution Science at (Sub)Millimeter Wavelengths
L. D. Matthews, G. B. Crew, S. S. Doeleman +38
The Atacama Millimeter/submillimeter Array (ALMA) Phasing Project (APP) has developed and deployed the hardware and software necessary to coherently sum the signals of individual A…
Dynamical Imaging with Interferometry
Michael D. Johnson, Katherine L. Bouman, Lindy Blackburn +7
By linking widely separated radio dishes, the technique of very long baseline interferometry (VLBI) can greatly enhance angular resolution in radio astronomy. However, at any given…
A comparative study of amplitude calibrations for East-Asia VLBI Network: a-priori and template spectrum methods
Ilje Cho, Taehyun Jung, Guang-Yao Zhao +11
We present the results of comparative study of amplitude calibrations for East-Asia VLBI Network (EAVN) at 22 and 43 GHz using two different methods of an "a-priori" and a "templat…
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…
White Paper on East Asian Vision for mm/submm VLBI: Toward Black Hole Astrophysics down to Angular Resolution of 1~R
K. Asada, M. Kino, M. Honma +35
This White Paper details the intentions and plans of the East Asian Very Long Baseline Interferometry (VLBI) community for pushing the frontiers of millimeter/submillimeter VLBI. T…
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…
