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…
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 $^{…
Measuring the asymmetric expansion of the Fe ejecta of Cassiopeia A with XRISM/Resolve
Aya Bamba, Manan Agarwal, Jacco Vink +24
The expansion structure of supernova remnants (SNRs) is important for understanding not only how heavy elements are distributed into space, but also how supernovae explode. The eje…
Search for -ray emission from SNRs in the Large Magellanic Cloud: a new cluster analysis at energies above 4 GeV
Andrea Tramacere, Riccardo Campana, Enrico Massaro +3
A search for -ray emission from SNRs in the Large Magellanic Cloud (LMC) based on the detection of concentrations in the arrival direction Fermi-LAT images of photons at energie…
Evolution of X-ray Gas in SN 1987A from 2007 to 2021: Ring Fading and Ejecta Brightening Unveiled through Differential Emission Measure Analysis
Lei Sun, Salvatore Orlando, Emanuele Greco +4
As the nearest supernova (SN) observed since Kepler's SN of 1604, SN 1987A provides an unprecedented opportunity to study in detail the early evolution of supernova remnants (SNRs)…
Unusual X-ray Oxygen Line Ratios of SN 1987A Arising From the Absorption of Galactic Hot Interstellar Medium
Lei Sun, Salvatore Orlando, Emanuele Greco +5
Recent high-resolution X-ray spectroscopic studies have revealed unusual oxygen line ratios, such as the high O VII forbidden-to-resonance ratio, in several supernova remnants. Whi…
