A Probe of the Matter Content of Quasar Jets
M. Georganopoulos, D. Kazanas, E. S. Perlman +1
We propose a method for estimating the matter content of quasar jets which exhibit Chandra - detected knots in their kpc scale jets. The method relies on measuring the component of…

Ultrahigh Energy Cosmic Rays: New Physics or Old Physics?
F. W. Stecker
We consider the advantages of and the problems associated with hypotheses to explain the origin of ulthrahigh energy cosmic rays (UHECR: E > 10 EeV) and the "trans GZK" cosmic rays…
