Very Long Baseline Interferometry with the SKA Observatory

J. F. Radcliffe, J. Yang, Z. Paragi +129

Very Long Baseline Interferometry (VLBI) is a fundamental technique that combines signals from telescopes separated by thousands of kilometres to obtain some of the highest-resolut…

Trigonometric parallax and proper motion of Sagittarius A* measured by VERA using the new broad-band back-end system OCTAVE-DAS

Tomoaki Oyama, Takumi Nagayama, Aya Yamauchi +12

We successfully measured the trigonometric parallax of Sagittarius A* (Sgr A*) to be micro-arcseconds (as) using the VLBI Exploration of Radio Astrometry (VERA) with…

A heat-wave of accretion energy traced by masers in the G358-MM1 high-mass protostar

R. A. Burns, K. Sugiyama, T. Hirota +20

High-mass stars are thought to accumulate much of their mass via short, infrequent bursts of disk-aided accretion. Such accretion events are rare and difficult to observe directly…
