Exploring Large-Volume GAGG Scintillators for use in MeV Gamma-Ray Astrophysics
Daniel Shy, Richard Woolf, Bernard Phlips +2
Gamma-ray astrophysics in the MeV band is an exciting field in astronomy due to its potential for multi-messenger astrophysics. It has, however, remained under-explored when compar…
All-sky Medium Energy Gamma-ray Observatory: Exploring the Extreme Multimessenger Universe
Julie McEnery, Juan Abel Barrio, Ivan Agudo +182
The All-sky Medium Energy Gamma-ray Observatory (AMEGO) is a probe class mission concept that will provide essential contributions to multimessenger astrophysics in the late 2020s…
The All-sky Medium Energy Gamma-ray Observatory eXplorer (AMEGO-X) Mission Concept
Regina Caputo, Marco Ajello, Carolyn Kierans +52
The All-sky Medium Energy Gamma-ray Observatory eXplorer (AMEGO-X) is designed to identify and characterize gamma rays from extreme explosions and accelerators. The main science th…
Development of the ComPair gamma-ray telescope prototype
Daniel Shy, Carolyn Kierans, Nicolas Cannady +22
There is a growing interest in the science uniquely enabled by observations in the MeV range, particularly in light of multi-messenger astrophysics. The Compton Pair (ComPair) tele…
Background Measurements and Simulations of the ComPair Balloon Flight
Zachary Metzler, Nicholas Kirschner, Lucas Smith +31
ComPair, a prototype of the All-sky Medium Energy Gamma-ray Observatory (AMEGO), completed a short-duration high-altitude balloon campaign on August 27, 2023 from Fort Sumner, New…
ComPair-2: A Next Generation Medium Energy Gamma-ray Telescope Prototype
Regina Caputo, Carolyn Kierans, Nicholas Cannady +30
Many questions posed in the Astro2020 Decadal survey in both the New Messengers and New Physics and the Cosmic Ecosystems science themes require a gamma-ray mission with capabiliti…
Real-time Likelihood Methods for Improved Gamma-ray Transient Detection and Localization
Matthew Kerr, Wade Duvall, Neil Johnson +3
We present a maximum likelihood (ML) algorithm that is fast enough to detect gamma-ray transients in real time on low-performance processors often used for space applications. We v…
