On the acceleration of cosmic rays at the post-adiabatic shocks of supernova remnants
O. Petruk, R. Bandiera, T. Kuzyo +2
When a supernova remnant (SNR) interacts with the dense material of an interstellar cloud, its shock wave decelerates rapidly, and the post-shock temperature drops to levels that p…

Probing the potential high-energy messengers of the anticipated T Coronae Borealis outburst
O. Petruk, T. Kuzyo, S. Orlando +4
T Coronae Borealis (T CrB) is a nearby recurrent nova expected to erupt in the near future, offering a unique opportunity to study particle acceleration and high-energy emission fr…

On the properties of turbulence in the remnant of Tycho supernova
Oleh Petruk, Taras Kuzyo
We investigate the turbulent structures in the Tycho supernova remnant (SNR) by applying two-point autocorrelation and power spectral analyses to high-resolution X-ray and radio im…
