Ultra Heavy Cosmic Rays from Magnetars
Anirudh Patel, Rebecca Diesing, Brian Metzger
Matter ejected from the neutron star crust during a magnetar giant flare will undergo -process nucleosynthesis during decompression. Ultra heavy ions () can be acceler…
Detecting Neutrino Emission from Supernova Remnants: A Theoretically Motivated Target Catalog
Emily Simon, Rebecca Diesing, Damiano Caprioli +1
Galactic supernova remnants (SNRs) are thought to accelerate cosmic rays (CRs) to several PeV energies, but this has yet to be confirmed as general behavior. Although several sourc…
Shock Acceleration in the Intracluster Medium: Implications of Micromirror Confinement
Rebecca Diesing, Ludwig Böss, Damiano Caprioli
Merging galaxy clusters exhibit strong observational evidence for efficient particle acceleration in the intracluster medium (ICM), particularly in the form of synchrotron-emitting…
Suppression of Shock X-ray Emission in Novae from Turbulent Mixing with Cool Gas
Brian D. Metzger, Lachlan Lancaster, Rebecca Diesing
Shock interaction in classical novae occurs when a fast outflow from the white dwarf > 1000 km s/s collides with a slower, cooler shell of gas released earlier in the outburst. The…
Nonthermal Signatures of Radiative Supernova Remnants II: The Impact of Cosmic Rays and Magnetic Fields
Rebecca Diesing, Siddhartha Gupta
Near the ends of their lives, supernova remnants (SNRs) enter a "radiative phase," when efficient cooling of the postshock gas slows expansion. Understanding SNR evolution at this…
Nonthermal Signatures of Radiative Supernova Remnants
Rebecca Diesing, Minghao Guo, Chang-Goo Kim +2
The end of supernova remnant (SNR) evolution is characterized by a so-called "radiative" stage, in which efficient cooling of the hot bubble inside the forward shock slows expansio…
The Maximum Energy of Shock-Accelerated Cosmic Rays
Rebecca Diesing
Identifying the accelerators of Galactic cosmic ray protons (CRs) with energies up to a few PeV ( eV) remains a theoretical and observational challenge. Supernova remnants…
Hadronic versus leptonic origin of gamma-ray emission from supernova remnants
N. Corso, R. Diesing, D. Caprioli
GeV and TeV emission from the forward shocks of supernova remnants (SNRs) indicates that they are capable particle accelerators, making them promising sources of Galactic cosmic ra…
Evidence for multiple shocks from the -ray emission of RS Ophiuchi
Rebecca Diesing, Brian D. Metzger, Elias Aydi +4
In August of 2021, Fermi-LAT, H.E.S.S., and MAGIC detected GeV and TeV -ray emission from an outburst of recurrent nova RS Ophiuchi. This detection represents the first very hig…
Galactic Cosmic Ray Acceleration with Steep Spectra
Rebecca Diesing, Damiano Caprioli
Galactic cosmic rays (CRs) are accelerated by astrophysical shocks, primarily supernova remnants (SNRs), via diffusive shock acceleration (DSA), an efficient mechanism that predict…
Steep Cosmic Ray Spectra with Revised Diffusive Shock Acceleration
Rebecca Diesing, Damiano Caprioli
Galactic cosmic rays (CRs) are accelerated at the forward shocks of supernova remnants (SNRs) via diffusive shock acceleration (DSA), an efficient acceleration mechanism that predi…
Nonsecondary origin of cosmic ray positrons
Rebecca Diesing, Damiano Caprioli
We investigate the possibility of secondary production as the source of cosmic ray (CR) positrons, taking into account observed electron and antiproton spectra and allowing that th…
Anomalous ANITA air shower events and tau decays
Shoshana Chipman, Rebecca Diesing, Mary Hall Reno +1
Two unusual neutrino events in the Antarctic Impulse Transient Antenna (ANITA) appear to have been generated by air showers from a particle emerging from the Earth at angles 25-35…
On the Spectrum of Electrons Accelerated in Supernova Remnants
Rebecca Diesing, Damiano Caprioli
Using a semi-analytic model of non-linear diffusive shock acceleration, we model the spectrum of cosmic ray (CR) electrons accelerated by supernova remnants (SNRs). Because electro…
Effect of Cosmic Rays on the Evolution and Momentum Deposition of Supernova Remnants
Rebecca Diesing, Damiano Caprioli
Using a semianalytical approach based on the thin-shell approximation, we calculate the long-term evolution of supernova remnants (SNRs) while also accounting for the cosmic rays (…
