First Very Long Baseline Interferometry Detections at 870μm
Alexander W. Raymond, Sheperd S. Doeleman, Keiichi Asada +276
The first very long baseline interferometry (VLBI) detections at 870m wavelength (345GHz frequency) are reported, achieving the highest diffraction-limited angular resolutio…
Absolute Flux Density Calibration of the Greenland Telescope Data for Event Horizon Telescope Observations
J. Y. Koay, K. Asada, S. Matsushita +35
Starting from the observing campaign in April 2018, the Greenland Telescope (GLT) has been added as a new station of the Event Horizon Telescope (EHT) array. Visibilities on baseli…
The Greenland Telescope: Construction, Commissioning, and Operations in Pituffik
Ming-Tang Chen, Keiichi Asada, Satoki Matsushita +51
In 2018, the Greenland Telescope (GLT) started scientific observation in Greenland. Since then, we have completed several significant improvements and added new capabilities to the…
Hybrid Very Long Baseline Interferometry Imaging and Modeling with Themis
Avery E. Broderick, Dominic W. Pesce, Paul Tiede +2
Generating images from very long baseline interferometric observations poses a difficult, and generally not unique, inversion problem. This problem is simplified by the introductio…
SYMBA: An end-to-end VLBI synthetic data generation pipeline
F. Roelofs, M. Janssen, I. Natarajan +203
Realistic synthetic observations of theoretical source models are essential for our understanding of real observational data. In using synthetic data, one can verify the extent to…
Properties of Trans-fast Magnetosonic Jets in Black Hole Magnetospheres
Hung-Yi Pu, Masaaki Takahashi
Traveling across several order of magnitude in distance, relativistic jets from strong gravity region to asymptotic flat spacetime region are believed to consist of several general…
