We evaluate the current status of supernova remnants as the sources of Galactic cosmic
rays. We summarize observations of supernova remnants, covering the whole …

The giant molecular clouds (MCs) found in the Milky Way and similar galaxies play a crucial
role in the evolution of these systems. The supernova explosions that mark the death of …

We present the AGILE gamma-ray observations in the energy range 50 MeV–10 GeV of the
supernova remnant (SNR) W44, one of the most interesting systems for studying cosmic-ray …

Recent observations of supernova remnants (SNRs) hint that they accelerate cosmic rays to
energies close to~ 1015 electron volts. However, the nature of the particles that produce the …

As a product of the maser monitoring program with the 26 m telescope of the
Hartebeesthoek Radio Astronomy Observatory (HartRAO), we present an unprecedented …

Aims. We present new Very Large Array (VLA) radio images at 74 and 324 MHz of the SNR
W44. The VLA images, obtained with unprecedented angular resolution and sensitivity for …

We present the results of GBT observations of all four ground-state hydroxyl (OH) transitions
toward 15 supernova remnants (SNRs) which show OH (1720 MHz) maser emission. This …

Here I present a survey of magnetic fields in large objects, from the interstellar supershells
(10pc) up to the edge of the Universe (near a redshift z of 10), with an emphasis on …

Recent observations reveal that spectral breaks at∼ GeV are commonly present in Galactic
γ-ray supernova remnants (SNRs) interacting with molecular clouds and that most of them …

Supernova remnants (SNRs) have been prime candidates for Galactic cosmic-ray
accelerators. When low-energy cosmic-ray protons (LECRp) collide with interstellar gas …
