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…
Proto-Neutron Star Winds, Magnetar Birth, and Gamma-Ray Bursts
B. D. Metzger, T. A. Thompson, E. Quataert
We begin by reviewing the theory of thermal, neutrino-driven proto-neutron star (PNS) winds. Including the effects of magnetic fields and rotation, we then derive the mass and ener…
Relativistic MHD Winds from Rotating Neutron Stars
N. Bucciantini, T. A. Thompson, J. Arons +1
We solve the time-dependent dynamics of axisymmetric, general relativistic MHD winds from rotating neutron stars. The mass loss rate is obtained self consistently as a solution of…
