A multi-Physics Experiment for Low-Yield Nuclear Explosion Monitoring Open
A series of multi-physics experiments, referred to as Physics Experiment 1 (PE1) is underway at the United States’ Nevada National Security Site (NNSS). The PE1 series includes detonations of three underground chemical explosions in P-tunn…

A VLBA movie of the jet launch region in M87 Open
M87 has one of the largest angular size black holes known. It also has a bright jet that is well resolved across the jet near the core using high frequency VLBI. As such it is the best object to observe to study the launch region of jets w…

Locating Earth Disturbances Using the SDR Earth Imager Open
The Radio Wave Phase Imager uses monitoring and recording concepts, such as Software Defined Radio (SDR), to image Earth’s atmosphere. The Long Wavelength Array (LWA), New Mexico Observatory is considered a high-resolution camera that obta…

Vehicle Tracking Open
The detection and tracking of vehicles moving at hypersonic speeds (> Mach 5) at altitudes of ~100 km has been of growing interest due to the ongoing development of hypersonic glide vehicles (HGVs) by the U.S., Russia and China. This chall…

Ancho Canyon RF Collect, March 2, 2017: Final Report Open
We report the results from the March 2, 2017, Ancho Canyon RF collection. While bright electromagnetic signals were seen nearby the firing point, there were no detections of signals from the explosively-fired fuse at a collection point abo…

June 2017 Ancho Canyon RF Collects: Final Report Open
We report the results from the June 8, 2017, Ancho Canyon RF collection. While bright, electromagnetic signals were seen close to the firing point, there were no detections of signals from the explosively-fired fuse (EFF) at a collection p…

Analysis framework for systematically studying ionospheric response to impulsive events from below Open
Impulsive phenomena in the Earth's atmosphere produce acoustic and gravity waves which perturb the ionosphere. Such perturbations are often measured using total electron content fluctuations (TEC), derived from ground‐based Global Position…

Observations of the Structure and Dynamics of the Inner M87 Jet Open
M87 is the best source in which to study a jet at high resolution in gravitational units because it has a very high mass black hole and is nearby. The angular size of the black hole is second only to Sgr A*, which does not have a strong je…
