About

The MeV gamma-ray sky remains the least explored window in the astrophysical electromagnetic spectrum, with no current or approved mission providing continuous all-sky coverage and precise source localization in this band. I will discuss GALAXIS, an idea that developed into a full-scale collaboration to design, build, and launch a telescope designed to fill this gap. Originally motivated by the search for QCD axions from core-collapse supernovae, GALAXIS has evolved into a multi-purpose MeV observatory whose science cases include exciting opportunities for both astrophysics and BSM physics; these include gamma-ray burst detection and localization, as well as powerful sensitivity to decaying dark matter across largely unprobed parameter space. I will describe the path from particle physics motivation to astrophysical observatory, and the path forward toward realizing GALAXIS as an instrument that will actually launch in the near future.
