Measuring photon rings with the ngeht

HIGHLIGHTS

  • who: Paul Tiede et al. from the Center for Astrophysics have published the Article: Measuring Photon Rings with the ngEHT, in the Journal: Galaxies 2022, 10, 111. of 24/Oct/2022
  • what: The authors explore the prospects for detecting and measuring the photon ring using very long baseline interferometry (VLBI) with the Event Horizon Telescope (EHT) and the next-generation EHT (ngEHT). Using the Bayesian modeling package Comrade.jl the authors show that the results of hybrid imaging must be interpreted with extreme caution for both photon ring detection and measurement-hybrid imaging readily produces . . .
