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…
Modeling the Saturation of the Bell Instability using Hybrid Simulations
Georgios Zacharegkas, Damiano Caprioli, Colby Haggerty +2
The nonresonant streaming instability (Bell instability) plays a pivotal role in the acceleration and confinement of cosmic rays (CRs); yet, the exact mechanism responsible for its…
A Kinetic Study of the Saturation of the Bell Instability
Georgios Zacharegkas, Damiano Caprioli, Colby Haggerty +1
The nonresonant cosmic ray instability, predicted by Bell (2004), is thought to play an important role in the acceleration and confinement of cosmic rays (CR) close to supernova re…
Cosmic rays from massive star clusters : A close look at Westerlund 1
Sourav Bhadra, Siddhartha Gupta, Biman B. Nath +1
We study the effect of cosmic ray (CR) acceleration in the massive compact star cluster Westerlund 1 in light of its recent detection in -rays. Recent observations reveal a $1/r…
