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…
Quasi-periodic variation during a fast X-ray outburst of a high-mass X-ray binary MAXI J0709-159 / LY CMa observed by NICER
Mutsumi Sugizaki, Tatehiro Mihara, Kohei Kobayashi +6
We report on a quasi-periodic variation at Hz during a fast X-ray outburst of a high-mass X-ray binary MAXI J0709159 / LY CMa observed by the Neutron-star interior compo…
Characterizing, correcting, and repairing the effects of radiation damage in the COSI germanium cross-strip detectors
Steven E. Boggs, Sophia E. Haight, Sean N. Pike +5
The Compton Spectrometer and Imager (COSI) is a gamma-ray survey telescope utilizing a compact Compton imager design, enabled by an array of 16 high-resolution germanium cross-stri…
In-orbit Spectral Calibration Prospects for the COSI Space Telescope
Aravind B. Valluvan, Steven E. Boggs, Savitri Gallego +8
The Compton Spectrometer and Imager is an upcoming NASA space telescope in the MeV range. COSI's primary science goals include precisely mapping nuclear line and positron annihilat…
Investigating MAXI J1752-457 with NuSTAR in the aftermath of a superburst
Sean N. Pike, Hitoshi Negoro, Douglas Buisson +5
We present two NuSTAR observations of the X-ray transient, MAXI J1752-457, following a superburst which was observed by MAXI/GSC in November, 2024. NuSTAR follow-up confirmed that…
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…
Proton Radiation Damage and Annealing of COSI p-type Cross-strip HPGe Detectors
Sophia E. Haight, Steven E. Boggs, Gabriel Brewster +7
In order to understand the effects of a space radiation environment on cross-strip germanium detectors, we investigated the effects of high-energy proton damage on a COSI detector…
Imaging and Spectral Fitting of Bright Gamma-ray Sources with the COSI Balloon Payload
Jarred M. Roberts, Steven Boggs, Thomas Siegert +17
The Compton Spectrometer and Imager balloon payload (COSI-Balloon) is a wide-field-of-view Compton -ray telescope that operates in the 0.2 - 5 MeV bandpass. COSI-Balloon had a s…
Characterizing hole trap production due to proton irradiation in germanium cross-strip detectors
Sean N. Pike, Steven E. Boggs, Gabriel Brewster +6
We present an investigation into the effects of high-energy proton damage on charge trapping in germanium cross-strip detectors, with the goal of accomplishing three important meas…
