Future gamma-ray missions’ polarimetric prospects
High-energy astrophysics polarimetry may significantly benefit from e-ASTROGAM and from AMEGO mission proposals, since to date limited polarimetric measurements were performed in this domain, exclusively under...

Background for a gamma-ray satellite on a low-Earth orbit
The different background components in a low-Earth orbit have been modeled in the 10 keV to 100 GeV energy range. The model is based on data from previous instruments and it considers both primary and secondar...

Asymmetries in core-collapse supernovae from maps of radioactive 44Ti in Cassiopeia A
The observation of non-uniformly distributed titanium emission in the interior of Cassiopeia A, a core-collapse supernova, is an indicator of asymmetries in the stellar explosion and provides strong evidence f...

Open AccessGamma-ray burst investigation via polarimetry and spectroscopy (GRIPS)
The primary scientific goal of the GRIPS mission is to revolutionize our understanding of the early universe using γ-ray bursts. We propose a new generation gamma-ray observatory capable of unprecedented spectros...

Monte Carlo study of detector concepts for the MAX Laue lens gamma-ray telescope
MAX is a proposed Laue lens gamma-ray telescope taking advantage of Bragg diffraction in crystals to concentrate incident photons onto a distant detector. The Laue lens and the detector are carried by two sepa...

An exceptionally bright flare from SGR 1806–20 and the origins of short-duration γ-ray bursts
Soft-γ-ray repeaters (SGRs) are galactic X-ray stars that emit numerous short-duration (about 0.1 s) bursts of hard X-rays during sporadic active periods. They are thought to be magnetars: strongly magnetized ...
