Revisiting the Role of the Streaming Instability for the Cosmic-Ray Spectrum in the GeV-to-TeV Range

The Astrophysical Journal
A complete understanding of the cosmic-ray energy spectrum remains a challenge to theory that must be met by comprehensive modeling efforts. One of these is the subject of the present study, namely, an explanation of the recently discovered spectral ...

Learning to See: Applying Inverse Recurrent Inference Machines to See through Refractive Scattering

The Astrophysical Journal
The Event Horizon Telescope (EHT) has produced horizon-resolving images of Sagittarius A* (Sgr A*). Scattering in the turbulent plasma of the interstellar medium distorts the appearance of Sgr A* on scales only marginally smaller than the fiducial ...
