Selective Dynamical Imaging of Interferometric Data
Joseph Farah, Peter Galison, Kazunori Akiyama +16
Recent developments in very long baseline interferometry (VLBI) have made it possible for the Event Horizon Telescope (EHT) to resolve the innermost accretion flows of the largest…
First Sagittarius A* Event Horizon Telescope Results. II. EHT and Multi-wavelength Observations, Data Processing, and Calibration
The Event Horizon Telescope Collaboration
We present Event Horizon Telescope (EHT) 1.3 mm measurements of the radio source located at the position of the supermassive black hole Sagittarius A* (Sgr A*), collected during th…
First M87 Event Horizon Telescope Results. I. The Shadow of the Supermassive Black Hole
The Event Horizon Telescope Collaboration
When surrounded by a transparent emission region, black holes are expected to reveal a dark shadow caused by gravitational light bending and photon capture at the event horizon. To…
Microarcsecond VLBI pulsar astrometry with PSR II. parallax distances for 57 pulsars
A. T. Deller, W. M. Goss, W. F. Brisken +8
We present the results of PSR, a large astrometric project targeting radio pulsars using the Very Long Baseline Array (VLBA). From our astrometric database of 60 pulsars, we hav…
A Repeating Fast Radio Burst
L. G. Spitler, P. Scholz, J. W. T. Hessels +21
Fast Radio Bursts are millisecond-duration astronomical radio pulses of unknown physical origin that appear to come from extragalactic distances. Previous follow-up observations ha…
The NANOGrav Nine-year Data Set: Limits on the Isotropic Stochastic Gravitational Wave Background
Zaven Arzoumanian, Adam Brazier, Sarah Burke-Spolaor +45
We compute upper limits on the nanohertz-frequency isotropic stochastic gravitational wave background (GWB) using the 9-year data release from the North American Nanohertz Observat…
