New Constraints on Cosmic Particle Populations at the Galactic Center using X-ray Observations of the Molecular Cloud Sagittarius B2
Field Rogers, Shuo Zhang, Kerstin Perez +2
The Sagittarius B2 (Sgr B2) molecular cloud complex is an X-ray reflection nebula whose total emissions have continued to decrease since 2001 as it reprocesses one or more past ene…
Large-area Si(Li) detectors for X-ray spectrometry and particle tracking in the GAPS experiment
Field Rogers, Mengjiao Xiao, Kerstin M. Perez +14
The first lithium-drifted silicon (Si(Li)) detectors to satisfy the unique geometric, performance, and cost requirements of the General Antiparticle Spectrometer (GAPS) experiment…
Passivation of Si(Li) detectors operated above cryogenic temperatures for space-based applications
Nathan Saffold, Field Rogers, Mengjiao Xiao +12
This work evaluates the viability of polyimide and parylene-C for passivation of lithium-drifted silicon (Si(Li)) detectors. The passivated Si(Li) detectors will form the particle…
Fabrication of low-cost, large-area prototype Si(Li) detectors for the GAPS experiment
Kerstin Perez, Tsuguo Aramaki, Charles J. Hailey +14
A Si(Li) detector fabrication procedure has been developed with the aim of satisfying the unique requirements of the GAPS (General Antiparticle Spectrometer) experiment. Si(Li) det…
The Compton Spectrometer and Imager
John A. Tomsick, Steven E. Boggs, Andreas Zoglauer +72
The Compton Spectrometer and Imager (COSI) is a NASA Small Explorer (SMEX) satellite mission in development with a planned launch in 2027. COSI is a wide-field gamma-ray telescope…
An Indirect Dark Matter Search Using Cosmic-Ray Antiparticles with GAPS
Alexander Lowell, Tsuguo Aramaki, Ralph Bird +30
Experiments aiming to directly detect dark matter (DM) particles have yet to make robust detections, thus underscoring the need for complementary approaches such as searches for ne…
