Revisiting γ-Ray Emission of the Supernova Remnant RCW 103
The Astrophysical JournalWe analyze more than 15 yr of γ -ray data obtained with the Large Area Telescope (LAT) on board the Fermi Gamma-ray Space Telescope (Fermi) for the region of the young supernova remnant (SNR) RCW 103, since the nearby source 4FGL J1616.2−5054e ...

Positron Annihilation Spectroscopy of Young Supernova Remnants
Odessa Astronomical Publications, 2018 This paper discusses radiative and thermodynamic properties of cold rarefied aggregates of non-uniformly distributed gas and dust through which high fluxes of positrons with energies of 0.011-3.6 MeV pass.

Modelling high-resolution spatially-resolved Supernova Remnant spectra with the Sardinia Radio Telescope [PDF]
, 2016 Supernova Remnants (SNRs) exhibit spectra featured by synchrotron radio emission arising from the relativistic electrons, and high-energy emission from both leptonic (Bremsstrahlung and Inverse Compton) and hadronic processes (π0 mesons decay) which are ...

Radio Emission from 16 Possible Supernova Remnants
, 1969 Sixteen radio sources, thought to be supernova remnants, have been observed at several frequencies between 408 and 2700 MHz. These data, together with previously published observations, have been used to derive spectra for these sources.

The Astrophysical JournalWe systematically study how cooling creates structural changes in supernova remnants as they evolve. Inspired by the peculiar morphology of the Pa 30 nebula, we adopt a framework in which to characterize supernova remnants under different degrees of ...

X-Ray Emission Properties of Supernova Remnants
, 2016 X-ray emission from supernova remnants can be broadly divided into thermal X-ray emission from the shock-heated plasmas and in nonthermal (synchrotron) emission caused by very high-energy (10–100 TeV) electrons moving in the magnetic fields of the hot ...

Mapping the Dense Molecular Gas toward 13 Supernova Remnants
The Astrophysical JournalSupernova remnants (SNRs) can exert strong influence on molecular clouds (MCs) through interaction by shock wave and cosmic rays. In this paper, we present our mapping observation of HCO ^+ and $\mathrm{HCN}$ 1–0 lines toward 13 SNRs interacting with MCs,

Nonthermal Signatures of Radiative Supernova Remnants
The Astrophysical JournalThe end of supernova remnant (SNR) evolution is characterized by a so-called “radiative” stage, in which efficient cooling of the hot bubble inside the forward shock slows expansion, leading to eventual shock breakup.

Supernova Remnants with Fermi Large Area Telescope
EPJ Web of Conferences, 2017 The Large Area Telescope (LAT), on-board the Fermi satellite, proved to be, after 8 years of data taking, an excellent instrument to detect and observe Supernova Remnants (SNRs) in a range of energies running from few hundred MeV up to few hundred GeV ...
