Dust-driven streaming instability and magnetic field amplification downstream of supernova remnant shocks
S. Gabici, J. C. Raymond, A. Ciardi +3
The acceleration of cosmic rays up to PeV energies at supernova remnant shocks requires an amplification of the ambient magnetic field. The amplification mechanism must operate ups…

Transient gamma rays from the 2021 outburst of the recurrent nova RS Ophiuchi: the effect of gamma-ray absorption
Vo Hong Minh Phan, Pierre Cristofari, Enrico Peretti +2
In 2021, RS Ophiuchi was the first nova to be detected in the very-high-energy (TeV) gamma-ray domain, directly testifying of efficient acceleration of charged particles up to at l…
