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…
Quantifying Intrinsic Variability of Sagittarius A* using Closure Phase Measurements of the Event Horizon Telescope
Freek Roelofs, Michael D. Johnson, Hotaka Shiokawa +2
General relativistic magnetohydrodynamic (GRMHD) simulations of accretion disks and jets associated with supermassive black holes show variability on a wide range of timescales. On…
Locating the intense interstellar scattering towards the inner Galaxy
J. Dexter, A. Deller, G. C. Bower +9
We use VLBA+VLA observations to measure the sizes of the scatter-broadened images of 6 of the most heavily scattered known pulsars: 3 within the Galactic Centre (GC) and 3 elsewher…
