Radio component of the multi-messenger emission from the anticipated T Coronae Borealis outburst
O. Petruk, T. Kuzyo, S. Orlando +4
T Coronae Borealis is the nearest symbiotic recurrent nova and is expected to undergo a new eruption soon, offering a rare opportunity to study shock evolution and particle acceler…
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 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…
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…
Three-dimensional velocity fields in the silicon- and sulfur-reach ejecta in the remnant of Tycho supernova
O. Petruk, M. Patrii, T. Kuzyo +3
The three-dimensional velocity structure of the shock-heated Si-reach and S-reach ejecta were reconstructed in Tycho supernova remnant from Doppler-shifted lines. The vector compon…
Evidence of gradients of density and magnetic field in the remnant of Tycho's supernova
Oleh Petruk, Taras Kuzyo, Mariana Patrii +5
By using surface brightness maps of Tycho's supernova remnant (SNR) in radio and X-rays, along with the properties of thermal and synchrotron emission, we have derived the post-sho…
Individual particle approach to the diffusive shock acceleration. Effect of the non-uniform flow velocity downstream of the shock
O. Petruk, T. Kuzyo
The momentum distribution of particles accelerated at strong non-relativistic shocks may be influenced by the spatial distribution of the flow speed around the shock. This phenomen…
Magneto-hydrodynamic simulations of young supernova remnants and their energy-conversion phase
O. Petruk, T. Kuzyo, S. Orlando +2
Supernova remnants (SNRs) can be rich sources of information on the parent SN explosion. Thus investigating the transition from the phase of SN to that of SNR can be crucial to lin…
Cosmic-ray acceleration and escape from post-adiabatic Supernova remnants
Robert Brose, Martin Pohl, Iurii Sushch +2
Supernova remnants are known to accelerate cosmic rays on account of their non-thermal emission of radio waves, X-rays, and gamma rays. Although there are many models for the accel…
Post-adiabatic supernova remnants in an interstellar magnetic field: oblique shocks and non-uniform environment
O. Petruk, T. Kuzyo, S. Orlando +5
We present very-high-resolution 1D MHD simulations of the late-stage supernova remnants (SNR). In the post-adiabatic stage the magnetic field has an important and significant dynam…
Post-adiabatic supernova remnants in the interstellar magnetic field. Parallel and perpendicular shocks
O. Petruk, T. Kuzyo, V. Beshley
Gamma-rays from hadronic collisions are expected from supernova remnants (SNRs) located near molecular clouds. The temperature on the shock interacting with the dense environment q…
Constraints on magnetic field strength in the remnant SN1006 from its nonthermal images
O. Petruk, T. Kuzyo, F. Bocchino
Images of SN1006 have a number of important properties. For instance, the bright limbs coincide spatially in various bands, they have different brightness, and the contrast of brig…
