Imaging the positron annihilation line with 20 years of INTEGRAL/SPI observations
Hiroki Yoneda, Thomas Siegert, Saurabh Mittal
The e e annihilation line at 511 keV provides a unique probe for studying the distribution and origin of positrons in our Galaxy. The SPI spectrometer on INTEGRAL has obser…
Light WIMPs and MeV Gamma-ray Detection with COSI
Yu Watanabe, Shigeki Matsumoto, Christopher M. Karwin +6
Light weakly interacting massive particles (WIMPs), whose masses are in the sub-GeV scale, have been attracting more attention due to the negative results searching for traditional…
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 s…
