Rare K decay with implications for fundamental physics and geochronology
M. Stukel, L. Hariasz, P. C. F. Di Stefano +24
Potassium-40 is a widespread, naturally occurring isotope whose radioactivity impacts subatomic rare-event searches, nuclear structure theory, and estimated geological ages. A pred…
The Bright Optical flash and Afterglow from the Gamma-Ray Burst GRB 130427A
W. T. Vestrand, J. Wren, A. Panaitescu +9
The optical light that is generated simultaneously with the x-rays and gamma-rays during a gamma-ray burst (GRB) provides clues about the nature of the explosions that occur as mas…
An in-vacuum diffractometer for resonant elastic soft x-ray scattering
D. G. Hawthorn, F. He, L. Venema +13
We describe the design, construction and performance of a 4-circle in-vacuum diffractometer for resonant elastic soft x-ray scattering and reflectivity. The diffractometer, install…
A Link between Prompt Optical and Prompt Gamma-Ray Emission in Gamma-Ray Bursts
W. T. Vestrand, P. R. Wozniak, J. A. Wren +20
The prompt optical emission that arrives with gamma-rays from a cosmic gamma-ray burst (GRB) is a signature of the engine powering the burst, the properties of the ultra-relativist…
A novel experimental system for the KDK measurement of the K decay scheme relevant for rare event searches
M. Stukel, B. C. Rasco, N. T. Brewer +26
Potassium-40 (K) is a long-lived, naturally occurring radioactive isotope. The decay products are prominent backgrounds for many rare event searches, including those involvi…
TALON - The Telescope Alert Operation Network System: Intelligent Linking of Distributed Autonomous Robotic Telescopes
R. R. White, J. Wren, H. Davis +4
The internet has brought about great change in the astronomical community, but this interconnectivity is just starting to be exploited for use in instrumentation. Utilizing the int…
