Not Where You Left Them: Displaced -Rays and X-Rays Reveal the Cosmic Ray Scattering Rate
Manami Roy, Mark R. Krumholz, Roland M. Crocker +1
Modern X-ray and -ray instruments are revealing a growing class of Galactic non-thermal sources whose emission centroids are measurably offset from the nearest plausible sites…
Fast X-ray Transient Detection with AXIS: application to Magnetar Giant Flares
Michela Negro, Zorawar Wadiasingh, George Younes +6
Magnetar giant flares (MGFs) are among the most luminous high-energy transients in the local universe, consisting of a short, intense MeV gamma-ray spike followed by a softer, puls…
Heavy element nucleosynthesis in rotating proto-magnetar winds
Tejas Prasanna, Matthew S. B. Coleman, Todd A. Thompson +3
The astrophysical origin of elements synthesized through the rapid neutron capture process (process) is a long standing mystery. The hot and dense environments of core-collapse…
r-Process Nucleosynthesis and Radioactively Powered Transients from Magnetar Giant Flares
Anirudh Patel, Brian D. Metzger, Jared A. Goldberg +3
We present nucleosynthesis and light-curve predictions for a new site of the rapid neutron capture process (-process) from magnetar giant flares (GFs). Motivated by observations…
Direct evidence for r-process nucleosynthesis in delayed MeV emission from the SGR 1806-20 magnetar giant flare
Anirudh Patel, Brian D. Metzger, Jakub Cehula +3
The origin of heavy elements synthesized through the rapid neutron capture process (-process) has been an enduring mystery for over half a century. Cehula et al. (2024) recently…
