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 o…
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…
Favorable conditions for heavy element nucleosynthesis in rotating proto-magnetar winds
Tejas Prasanna, Matthew S. B. Coleman, Todd A. Thompson
The neutrino-driven wind cooling phase of proto-neutron stars (PNSs) follows successful supernovae. Wind models without magnetic fields or rotation fail to achieve the necessary co…
Dynamics of baryon ejection in magnetar giant flares: implications for radio afterglows, r-process nucleosynthesis, and fast radio bursts
Jakub Cehula, Todd A. Thompson, Brian D. Metzger
We explore the impact of a magnetar giant flare (GF) on the neutron star (NS) crust, and the associated baryon mass ejection. We consider that sudden magnetic energy dissipation cr…
Prospects for detecting proto-neutron star rotation and spindown using supernova neutrinos
Tejas Prasanna, Todd A. Thompson, Christopher Hirata
After a successful supernova, a proto-neutron star (PNS) cools by emitting neutrinos on s timescales. Provided that there are neutrino emission `hot-spots' or `cold-sp…
CONGRuENTS (COsmic-ray, Neutrino, Gamma-ray and Radio Non-Thermal Spectra). II. Population-level correlations between galactic infrared, radio, and γ-ray emission
Matt A. Roth, Mark R. Krumholz, Roland M. Crocker +1
Galaxies obey a number of empirical correlations between their radio, γ-ray, and infrared emission, but the physical origins of these correlations remain uncertain. Here we use the…
Magnetized Relativistic Jets and Long-Duration GRBs from Magnetar Spindown during Core-Collapse Supernovae
N. Bucciantini, E. Quataert, B. D. Metzger +3
We use ideal axisymmetric relativistic magnetohydrodynamic simulations to calculate the spindown of a newly formed millisecond, B ~ 10^{15} G, magnetar and its interaction with the…
