Cosmic ray acceleration by shocks: spectral steepening due to turbulent magnetic field amplification
Anthony Bell, James Matthews, Katherine Blundell
We show that the energy required to turbulently amplify magnetic field during cosmic ray (CR) acceleration by shocks extracts energy from the CR and steepens the CR energy spectrum…
Cosmic Ray Acceleration by Relativistic Shocks: Limits and Estimates
AR Bell, AT Araudo, JH Matthews +1
We examine limits to the energy to which cosmic rays can be accelerated by relativistic shocks, showing that acceleration of light ions as high as 100 EeV is unlikely. The implicat…
Particle acceleration and magnetic field amplification in the jets of 4C74.26
Anabella T. Araudo, Anthony R. Bell, Katherine M. Blundell
We model the multi-wavelength emission in the southern hotspot of the radio quasar 4C74.26. The synchrotron radio emission is resolved near the shock with the MERLIN radio-interfer…
Multiwavelength study of Cygnus A III. Evidence for relic lobe plasma
K. C. Steenbrugge, I. Heywood, K. M. Blundell
We study the particle energy distribution in the cocoon surrounding Cygnus A, using radio images between 151 MHz and 15 GHz and a 200 ks Chandra ACIS-I image. We show that the exce…
