Supernova remnants in the new radio astronomy era
A. Ingallinera, M. Arias, G. Castelletti +25
Supernova remnants (SNRs) are what is left after stellar explosions, when the stellar ejecta, the explosion shock and the circumstellar medium interact. Despite being among the fir…
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…
A New Catalogue of Galactic Red Supergiants for direct detection of episodic mass-loss events
M. Lauriano, F. Bocchino, M. Miceli +5
We present GalRSG, a new catalogue of 227 Galactic Red Supergiants in the Scutum-Crux region, which provides a nearly coeval and co-distant sample, target of a long-term, panchroma…
Predicting the X-ray signatures of the imminent T Coronae Borealis outburst through 3D hydrodynamic modeling
S. Orlando, L. Chomiuk, J. Drake +3
T Coronae Borealis (T CrB) is a symbiotic recurrent nova with eruptions in 1866 and 1946. Mounting evidence suggests an imminent outburst, offering a rare opportunity to observe a…
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…
