astro-ph.IM2025

Signal processing and data acquisition system for the BTO detectors onboard COSI

Shunsaku Nagasawa, Tadayuki Takahashi, Kazuhiro Nakazawa +15

The energy range from a few hundred keV to a few MeV includes important probes such as nuclear gamma-rays and the 511 keV annihilation line. However, compared to X-rays and GeV/TeV…

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…
