Probing Shocked Ejecta in SN 1987A: A novel diagnostic approach using XRISM-Resolve
Vincenzo Sapienza, Marco Miceli, Aya Bamba +10
Supernova (SN) 1987A is one of the best candidates to exploit the capabilities of the freshly launched XRISM satellite. This celestial object offers the unique opportunity to study…
Evidence for protons accelerated and escaped from the Puppis A region using \textit{Fermi}-LAT observations
Roberta Giuffrida, Marianne Lemoine-Gourmard, Marco Miceli +7
Supernova remnants (SNRs) interacting with molecular clouds are interesting laboratories to study the acceleration of cosmic rays and their propagation in the dense ambient medium.…
Measuring the initial mass of 44Ti in SN 1987A through the 44Sc emission line
Roberta Giuffrida, Marco Miceli, Emanuele Greco +7
Context. Deriving the mass and large-scale asymmetries of radioactive isotopes offers valuable insights into the complex phases of a supernova explosion. Important examples are $^{…
The supernova remnant SN 1006 as a Galactic particle accelerator
Roberta Giuffrida, Marco Miceli, Damiano Caprioli +6
The origin of cosmic rays is a pivotal open issue of high-energy astrophysics. Supernova remnants are strong candidates to be the Galactic factory of cosmic rays, their blast waves…
Probing Shocked Ejecta in SN 1987A with XRISM-Resolve: the effects of the gate valve closed
Vincenzo Sapienza, Marco Miceli, Aya Bamba +10
Supernova (SN) 1987A is widely regarded as an excellent candidate for leveraging the capabilities of the freshly launched XRISM satellite. Recent researches indicate that the X-ray…
Evidence for proton acceleration and escape from the Puppis A SNR using Fermi-LAT observations
Roberta Giuffrida, Marianne Lemoine-Goumard, Marco Miceli +3
Supernova remnants (SNRs) are the best candidates for galactic cosmic ray acceleration to relativistic energies via diffusive shock acceleration. The gamma-ray emission of SNRs can…
