Astroparticle Colloquia

The All-Sky Medium Energy Gamma-ray Observatory – a multimessenger mission for the Extreme Universe

Description

AMEGO will provide breakthrough capabilities in three areas of MeV astrophysics: a wide field of view and broad energy range will provide outstanding capability in time-domain astrophysics including excellent synergies with observations at other wavelengths; polarization sensitivity will uniquely probe conditions and processes in astrophysical jets and in the magnetospheres and winds of compact objects; and nuclear line spectroscopy will bring new insight into element formation in dynamic environments. AMEGO will consist of four hardware subsystems: a double-sided silicon strip tracker with analog readout, a segmented CZT calorimeter, a segmented CsI calorimeter and a plastic scintillator anticoincidence detector, and will operate primarily in an all-sky survey mode. In this talk, I will describe the AMEGO mission concept and scientific performance.
