Detectability of Polarized Gamma-ray Emission from Blazar Flares with COSI
Garrett A. Latiolais, Jorge Otero-Santos, Michela Negro +18
We investigate the detectability of polarized gamma-ray emission from blazar flares with the Compton Spectrometer and Imager (COSI). Using 17 years of Fermi Large Area Telescope ob…
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…
Pre-flight Background Estimates for COSI
Savitri Gallego, Uwe Oberlack, Jan Lommler +14
The Compton Spectrometer and Imager (COSI) is a Compton telescope designed to survey the 0.2 - 5 MeV sky, consisting of a compact array of cross-strip germanium detectors. It is pl…
Bottom-up Background Simulations of the 2016 COSI Balloon Flight
Savitri Gallego, Uwe Oberlack, Jan Lommler +8
The Compton Spectrometer and Imager (COSI) is a Compton telescope designed to survey the 0.2-5 MeV sky, consisting of a compact array of cross-strip germanium detectors. As part of…
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…
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…
