Enhanced imaging of M87*: Simulations with the EHT and extended-KVN
Ilje Cho, Jongho Park, Do-Young Byun +16
The Event Horizon Telescope (EHT) has successfully revealed the shadow of the supermassive black hole, M87*, with an unprecedented angular resolution of approximately 20 uas at 230…
Markov Chains for Horizons (MARCH). I. Identifying Biases in Fitting Theoretical Models to Event Horizon Telescope Observations
Dimitrios Psaltis, Feryal Ozel, Lia Medeiros +7
We introduce a new Markov Chain Monte Carlo (MCMC) algorithm with parallel tempering for fitting theoretical models of horizon-scale images of black holes to the interferometric da…
First M87 Event Horizon Telescope Results. II. Array and Instrumentation
The Event Horizon Telescope Collaboration
The Event Horizon Telescope (EHT) is a very long baseline interferometry (VLBI) array that comprises millimeter- and submillimeter-wavelength telescopes separated by distances comp…
Tilted Beam Measurement of VLBI Receiver for the South Pole Telescope
Junhan Kim, Daniel P. Marrone
We have developed a 230 and 345 GHz very-long-baseline interferometry (VLBI) receiver for the South Pole Telescope (SPT). With the receiver installed, the SPT has joined the global…
A VLBI receiving system for the South Pole Telescope
Junhan Kim, Daniel P. Marrone, Christopher Beaudoin +15
The Event Horizon Telescope (EHT) is a very-long-baseline interferometry (VLBI) experiment that aims to observe supermassive black holes with an angular resolution that is comparab…
