Locating the missing large-scale emission in the jet of M87* with short EHT baselines
Boris Georgiev, Paul Tiede, Sebastiano D. von Fellenberg +280
In Very-Long Baseline Interferometric arrays, nearly co-located stations probe the largest scales and typically cannot resolve the observed source. In the absence of large-scale st…

Interferometric inference of black hole spin from photon ring size and brightness
Joseph R. Farah, Alexandru Lupsasca, Eliot Quataert +1
The photon ring is a full image of the astrophysical source around a black hole, produced by photons that execute half-orbit around the event horizon on their way…

The First 4 Years of SN 1993J Revisited: Geometric -ring Modeling of the Radio Shell with Closure Quantities Only
Joseph R. Farah, Logan J. Prust, Giacomo Terreran +5
SN 1993J is the best-studied radio supernova, with observations using very-long-baseline interferometry (VLBI) spanning from within weeks of explosion through nearly three decades…
