Properties of Submillimeter Galaxies in the CANDELS GOODS-S Field

Tommy Wiklind, Christopher J. Conselice, Tomas Dahlen +29

We derive physical properties of 10 submillimeter galaxies located in the CANDELS coverage of the GOODS-S field. The galaxies were first identified as submillimeter sources with th…

First Dynamic Computation of Synchrotron Emission from the Cygnus A Radio Cavity; Evidence for Electron Pair Plasma in Cavity

William G. Mathews

Cosmic rays, thermal gas and magnetic fields in FRII radio cavities are assumed to come entirely from winds flowing from just behind the jet shocks. Combining analytic and computat…
