2014年3月5日 · The hadronic interpretation of the gamma-ray spectrum of W44 is viable, and supported by strong evidence. It implies a relatively large value for the average magnetic field …

2010年1月7日 · Our results for W44 demonstrate the capability of the Fermi LAT for morphological and spectral studies of GeV emission from Galactic SNRs, which allow us to …

4 天之前 · W44 is a exemplar case of a sedov phase SNR emitting in gamma-rays via hadronic interactions. The presence of a cutoff below TeV energies points to questions about the …

2012年11月14日 · The remnant of the supernova explosion, which goes by the name of “SNR W44”, comprises an expanding shell of warm dust and a bubble of extremely hot gas. The …

2012年10月1日 · W44 (G34.7-0.4) is one of the most studied Supernova Remnants (SNRs) because it is an ideal system to study Cosmic-Ray (CR) production, acceleration and …

6 天之前 · Observations of GeV gamma-ray emission from the well-studied mixed-morphology supernova remnant (SNR) W44 by Fermi-LAT and AGILE imply that it is a site of significant …

The SNR W44 is one of the most interesting SNRs observed so far; it is a middle-aged SNR, bright at gamma-ray energies, and quite close to us. Its gamma-ray spectral index (indicative …

1993年12月1日 · We analyze EXOSAT and Einstein Observatory X-ray spectra, an Einstein X-ray image, and a detailed VLA radio map of the SNR W44. The diffuse soft X-ray emission, which …

The middle-aged supernova remnant (SNR) W44 has recently attracted attention because of its relevance regarding the origin of Galactic cosmic-rays. For the first time for a SNR, the gamma …

W44 (G34.7-0.4) is one of the most studied Supernova Remnants (SNRs) because it is an ideal system to study Cosmic-Ray (CR) production, acceleration and propagation.
