abstract
The All-sky Medium Energy Gamma-ray Observatory (AMEGO) is a probe class mission concept that will provide essential contributions to multimessenger astrophysics in the late 2020s and beyond. AMEGO combines high sensitivity in the 200 keV to 10 GeV energy range with a wide field of view, good spectral resolution, and polarization sensitivity. Therefore, AMEGO is key in the study of multimessenger astrophysical objects that have unique signatures in the gamma-ray regime, such as neutron star mergers, supernovae, and flaring active galactic nuclei. The order-of-magnitude improvement compared to previous MeV missions also enables discoveries of a wide range of phenomena whose energy output peaks in the relatively unexplored medium-energy gamma-ray band.

A two-zone leptonic model inside a magnetically reconnecting jet reproduces the narrow TeV spike and simultaneous X-ray rise observed in Mrk 501 during its 2014 high state.
New 59Fe beta-decay rates in non-rotating MESA models suppress 60Fe yields by 0.28 dex, yielding a Salpeter-IMF-integrated 60Fe/26Al flux ratio of 0.18 that matches the observed 0.184 ± 0.042.
The paper develops a search algorithm to find observable MeV gamma-ray peaks from r-process isotope decays in mergers and shows Rh-106 can distinguish main versus weak r-process while Tl-208 remains robust across model variations.
This work sets new upper limits on decay lifetimes and couplings for axion-like particles, dark photons, scalars, and B-L or L_i-L_j vector bosons using 511 keV line, X-ray continuum, and cosmic-ray flux observations.
Sets upper limits on primordial black hole dark matter fraction using extragalactic gamma-ray background, claiming these are the tightest indirect constraints for the mass range.
Hadronic SED modeling of 103 blazar candidates predicts proton synchrotron peaks in the MeV band for 99 sources and maximum neutrino fluxes detectable by up to 62 sources with next-generation telescopes.
Future MeV telescopes could constrain axion-photon couplings to 1.61 × 10^{-13} GeV^{-1} for ALP masses below 10^{-9} eV using signals from galactic supernovae.
The paper evaluates how triangular versus two-L-shaped geometries, arm lengths, and presence of low-frequency instruments affect the science reach of the Einstein Telescope for compact binaries, multi-messenger events, and stochastic backgrounds.
