Journal ArticleDOI
On the Magnetic Fields and Particle Acceleration in Cassiopeia A
Jacco Vink,J. Martin Laming +1 more
TL;DR: In this article, the authors investigated the nonthermal X-ray emission from Cas A, using BeppoSAX, Compton Gamma Ray Observatory OSSE, and Chandra data, and constructed a simple two-zone model.

TL;DR: In this paper, the authors used HST images of the young supernova remnant Cas A to explore the expansion and spatial distribution of its highest velocity debris, and they found significant gaps in the spatial distribution in directions that are approximately perpendicular to the jets (P.A. = 145 degrees-200 degrees and 335 degrees-350 degrees).

A neutron star with a carbon atmosphere in the Cassiopeia A supernova remnant
Wynn C. G. Ho,Craig O. Heinke +1 more
TL;DR: This result suggests that there is nuclear burning in the surface layers and also identifies the compact X-ray source in the centre of the Cassiopeia supernova remnant as a very young (∼330-year-old) neutron star.
Journal ArticleDOI
Observational constraints on energetic particle diffusion in young supernovae remnants: amplified magnetic field and maximum energy
TL;DR: In this article, a joint study of the electrons diffusion and advection in the downstream medium of the supernova shock was carried out, and it was shown that the magnetic field must be amplified up to values between 250 and 500 µG in the case of Cas A, Kepler, and Tycho, or ∼100 µ Gi n in case of SN 1006 and G347.
Journal ArticleDOI
The Expansion Center and Dynamical Age of the Galactic Supernova Remnant Cassiopeia A
TL;DR: In this article, proper motions for 21 bright main shell and 17 higher velocity, outer ejecta knots in the Cas A supernova remnant were used to derive new estimates for the remnant's expansion center and age.

Journal ArticleDOI
A New Intense Source of Radio-Frequency Radiation in the Constellation of Cassiopeia
Martin Ryle,F. G. Smith +1 more
TL;DR: Bolton and Stanley as discussed by the authors showed that the angular diameter of the source was smaller than the resolving power of their apparatus (8 minutes of arc), and the more precise determination of its position enabled them to show that the source does not coincide with any outstanding star.
