AstroPix: A Pixelated HVCMOS Sensor for Space-Based Gamma-Ray Measurement
Amanda L. Steinhebel, Regina Caputo, Daniel P. Violette +33
A next-generation medium-energy gamma-ray telescope targeting the MeV range would address open questions in astrophysics regarding how extreme conditions accelerate cosmic-ray part…
Calibration of the ComPair Balloon Instrument
Nicholas Kirschner, Zachary Metzler, Lucas D. Smith +25
ComPair, the prototype of the All-sky Medium Energy Gamma-ray Observatory (AMEGO) mission concept, is a combined Compton imager and pair production telescope. It consists of four s…
Irradiated Pulsar Planets and Companions as 511 keV Positron Annihilation Line Sources
Zachary Metzler, Zorawar Wadiasingh
Millisecond pulsars (MSPs) are prolific GeV emitters, and nearly 80\% of Fermi-LAT MSPs reside in compact binaries. We demonstrate that the companions in these comp…
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…
A-STEP: The AstroPix Sounding Rocket Technology Demonstration Payload
Daniel P. Violette, Amanda Steinhebel, Abhradeep Roy +21
A next-generation medium-energy (100 keV to 100 MeV) gamma-ray observatory will greatly enhance the identification and characterization of multimessenger sources in the coming deca…
