Negative refraction in outer space?
Tom G. Mackay, Akhlesh Lakhtakia
Mediums which do not support the propagation of plane waves with negative phase velocity (NPV) when viewed at rest can support NPV propagation when they are viewed in a reference f…
An X-Ray Pulsar, Metal-rich Ejecta, and Shocked Ambient Medium in the Supernova Remnant G292.0+1.8
John P. Hughes, Robert B. Friedman, Patrick Slane +1
We report the discovery of pulsed X-ray emission from the compact object CXOU J112439.1-591620 within the Galactic supernova remnant G292.0+1.8 using the High Resolution Camera on…
Reversible and irreversible processes in dispersive/dissipative optical media: Electro-magnetic free energy and heat production
C. Broadbent, G. Hovhannisyan, M. Clayton +2
We solve the problem addressed by Landau and Lifshitz in 1958, and Oughstun and Sherman of determining the dynamical losses in a purely dissipative dielectric media. We develop con…
Avalanche Dynamics in Wet Granular Media
P. Tegzes, T. Vicsek, P. Schiffer
A detailed characterization of avalanche dynamics of wet granular media in a rotating drum apparatus is presented. The results confirm the existence of the three wetness regimes ob…
Real-time determination of free energy and losses in optical absorbing media
C. Broadbent, G. Hovhannisyan, J. Peatross +2
We introduce notions of free energy and loss in linear, absorbing dielectric media which are relevant to the regime in which the macroscopic Maxwell equations are themselves releva…
X-rays and regions of star formation: a combined ROSAT-HRI/near-to-mid IR study of the rho Oph dark cloud
Nicolas Grosso, Thierry Montmerle, Sylvain Bontemps +2
We have obtained two deep exposures of the rho Oph cloud core region with the ROSAT HRI. The improved position accuracy (1"-6") with respect to previous recent X-ray observations (…
