First Very Long Baseline Interferometry Detections at 870μm

Alexander W. Raymond, Sheperd S. Doeleman, Keiichi Asada +276

The first very long baseline interferometry (VLBI) detections at 870m wavelength (345GHz frequency) are reported, achieving the highest diffraction-limited angular resolutio…

First M87 Event Horizon Telescope Results. IX. Detection of Near-horizon Circular Polarization

The Event Horizon Telescope Collaboration

Event Horizon Telescope (EHT) observations have revealed a bright ring of emission around the supermassive black hole at the center of the M87 galaxy. EHT images in linear polariza…

Polarimetric Geometric Modeling for mm-VLBI Observations of Black Holes

Freek Roelofs, Michael D. Johnson, Andrew Chael +4

The Event Horizon Telescope (EHT) is a millimeter very long baseline interferometry (VLBI) array that has imaged the apparent shadows of the supermassive black holes M87* and Sagit…

First Sagittarius A* Event Horizon Telescope Results. VI: Testing the Black Hole Metric

The Event Horizon Telescope Collaboration

Astrophysical black holes are expected to be described by the Kerr metric. This is the only stationary, vacuum, axisymmetric metric, without electromagnetic charge, that satisfies…

First Sagittarius A* Event Horizon Telescope Results. V. Testing Astrophysical Models of the Galactic Center Black Hole

The Event Horizon Telescope Collaboration

In this paper, we provide a first physical interpretation for the Event Horizon Telescope (EHT)'s 2017 observations of Sgr A*. Our main approach is to compare resolved EHT data at…

A search for pulsars around Sgr A* in the first Event Horizon Telescope dataset

Pablo Torne, Kuo Liu, Ralph P. Eatough +282

The Event Horizon Telescope (EHT) observed in 2017 the supermassive black hole at the center of the Milky Way, Sagittarius A* (Sgr A*), at a frequency of 228.1 GHz (=1.3 mm). Th…

The Event Horizon Telescope Image of the Quasar NRAO 530

Svetlana Jorstad, Maciek Wielgus, Rocco Lico +27

We report on the observations of the quasar NRAO 530 with the Event Horizon Telescope (EHT) on 2017 April 5-7, when NRAO 530 was used as a calibrator for the EHT observations of Sa…

SYMBA: An end-to-end VLBI synthetic data generation pipeline

F. Roelofs, M. Janssen, I. Natarajan +203

Realistic synthetic observations of theoretical source models are essential for our understanding of real observational data. In using synthetic data, one can verify the extent to…
