Depth Calibration of Double-sided Strip Germanium Detectors for the Compton Spectrometer and Imager Satellite
Field R. Rogers, Sean N. Pike, Samer Alnussirat +12
Double-sided strip high-purity germanium detectors with three-dimensional position reconstruction capability have been developed over three decades, with space-based applications i…
Enhancing Compton telescope imaging with maximum a posteriori estimation: a modified Richardson-Lucy algorithm for the Compton Spectrometer and Imager
Hiroki Yoneda, Thomas Siegert, Israel Martinez-Castellanos +23
We present a modified Richardson-Lucy (RL) algorithm tailored for image reconstruction in MeV gamma-ray observations, focusing on its application to the upcoming Compton Spectromet…
A Study of Afterglow Signatures in NaI and CsI Scintillator Modules for the Background and Transient Observer Instrument on COSI
Hannah Gulick, Hiroki Yoneda, Tadayuki Takahashi +15
We present measurements of the afterglow signatures in NaI(Tl) and CsI(Tl) detector modules as part of the Background and Transient Observer (BTO) mission detector trade-study. BTO…
Across the soft gamma-ray regime: utilizing simultaneous detections in the Compton Spectrometer and Imager (COSI) and the Background and Transient Observer (BTO) to understand astrophysical transients
Hannah C. Gulick, Eliza Neights, Samer Al Nussirat +17
The Compton Spectrometer and Imager (COSI) is a NASA funded Small Explorer (SMEX) mission slated to launch in 2027. COSI will house a wide-field gamma-ray telescope designed to sur…
X-ray measurement of a high-mass white dwarf and its spin for the intermediate polar IGR J18434-0508
Julian Gerber, Jeremy Hare, John A. Tomsick +8
IGR J18434-0508 is a Galactic Intermediate Polar (IP) type Cataclysmic Variable (CV) previously classified through optical spectroscopy. The source is already known to have a hard…
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…
The cosipy library: COSI's high-level analysis software
Israel Martinez-Castellanos, Savitri Gallego, Chien-You Huang +72
The Compton Spectrometer and Imager (COSI) is a selected Small Explorer (SMEX) mission launching in 2027. It consists of a large field-of-view Compton telescope that will probe wit…
Gamma-ray Transient Network Science Analysis Group Report
Eric Burns, Michael Coughlin, Kendall Ackley +34
The Interplanetary Network (IPN) is a detection, localization and alert system that utilizes the arrival time of transient signals in gamma-ray detectors on spacecraft separated by…
Classifying IGR J15038-6021 as a magnetic CV with a massive white dwarf
John A. Tomsick, Snehaa Ganesh Kumar, Benjamin M. Coughenour +8
Cataclysmic variables (CVs) are binary systems consisting of a white dwarf (WD) accreting matter from a companion star. Observations of CVs provide an opportunity to learn about ac…
Multi-Resolution HEALPix Maps for Multi-Wavelength and Multi-Messenger Astronomy
I. Martinez-Castellanos, Leo P. Singer, E. Burns +4
HEALPix -- the Hierarchical Equal Area isoLatitude Pixelization -- has become a standard in high-energy and gravitational wave astronomy. Originally developed to improve the effici…
BurstCube: Concept, Performance, and Status
Jacob R. Smith, Michael S. Briggs, Alessandro Bruno +26
The first simultaneous detection of a short gamma-ray burst (SGRB) with a gravitational-wave (GW) signal ushered in a new era of multi-messenger astronomy. In order to increase the…
Gamma Rays and Gravitational Waves
E. Burns, S. Zhu, C. M. Hui +28
The first multimessenger observation of a neutron star merger was independently detected in gamma-rays by Fermi-GBM and INTEGRAL SPI-ACS and gravitational waves by Advanced LIGO an…
