Hard X-ray emission from accretion shocks around galaxy clusters (2009)
We show that the hard X-ray (HXR) emission observed from several galaxy clusters is naturally explained by a simple model, in which the nonthermal emission is produced by inverse Compton scattering...
Nonthermal emission from clusters of galaxies (2009)
We show that the spectral and radial distribution of the nonthermal emission of massive, M>10^{14.5}M_sun, galaxy clusters (GCs) may be approximately described by simple analytic expressions, which...
Magnetic fields and cosmic rays in clusters of galaxies (2009)
Kushnir, Doron, Katz, Boaz, Waxman, Eli
We argue that the observed correlation between the radio luminosity and the X-ray luminosity in radio emitting galaxy clusters implies that the radio emission is due to secondary electrons that are...
The stability of decelerating shocks revisited (2005)
Kushnir, Doron, Waxman, Eli, Shvarts, Dov
We present a new method for analyzing the global stability of the Sedov-von Neumann-Taylor self-similar solutions, describing the asymptotic behavior of spherical decelerating shock waves, expanding...
