Deciphering the "Green Monster" in Cassiopeia A: Puncturing and sculpting a heterogeneous circumstellar shell
S. Orlando, H. -T. Janka, D. Milisavljevic +6
JWST observations of Cassiopeia A have revealed the "Green Monster" (GM), a pockmarked region of shocked circumstellar medium (CSM) characterized by circular holes surrounded by br…
Efficient ion re-acceleration in laboratory-produced interpenetrating collisionless shocks
W. Yao, I. Cohen, P. Suarez Gerona +20
Although the origin of cosmic rays (CRs) remains an open question, collisionless magnetized shock waves are widely regarded as key sites for particle acceleration. Recent theories…
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…
Extreme anisotropies in deep layers of an exploding star: overabundance of Cr in the northeastern jet of Cassiopeia A
Vincenzo Sapienza, Marco Miceli, Masaomi Ono +5
Core-collapse supernovae drive nucleosynthesis under extreme thermodynamic conditions, and complex mechanisms are at work prompting the transport of heavy elements from deep stella…
Multi-wavelength study of the high Galactic latitude supernova remnant candidate G118.4+37.0 associated with the Calvera pulsar
Emanuele Greco, Michela Rigoselli, Sandro Mereghetti +4
The candidate supernova remnant (SNR) G118.4+37.0 (Calvera's SNR), discovered as a faint radio ring at high Galactic latitude and coincident with extended Fermi/LAT gamma-ray emiss…
