Excess Optical Enhancement Observed with ARCONS for Early
... observed have an important role in constraining models of pulsar emission. For example, Lommen et al. (2007) found that when the radio pulse of the Vela pulsar arrives early, there is an enhancement in the immediately following X-ray peak, although shot noise from the X-ray emission from the surroun ...

Metamaterial Electromagnetic Wave Absorbers
... Two canonical metamaterial elements are shown in Figure 1: in (a, d) the magnetic split ring resonator (SRR), and in (b, e) the electric ring resonator (ERR). Metamaterials allow for the explicit design of the effective parameters ε(ω) and μ(ω); they can be described with standard electromagnetic th ...

Laser and nonlinear optics
... this can also be achieved in the resonator if for example the laser is over-pumped beyond the oscillation threshold. This is advantageous because there are minimum diffraction losses for TEM00 . However, non-optimal adjustment can lead to higher TEMmn -modes (m, n ∈ IN) in the resonator with spatial ...

Lecture 16, AGN Evolution
... • X-ray data are consistent with many of the non-BLAGN (the dominant population) having high column densities • AGN evolve very rapidly to z~1.2, consistent with pure luminosity evolution to that redshift • z~1 is where the bulk of the supermassive black hole population forms • Simple unified model ...

... The onset of a local polarization can be determined by measuring the index of refraction [6], electrostictive strain [7], inverse dielectric permittivity [4] and lately also acoustic emission (AE) [8]. In addition, X-ray diffraction and neutron scattering techniques allow to monitor the majority of ...

Physics of the Interstellar and Intergalactic Medium
... Now suppose that we want to observe 21cm radiation from gas at redshift z = 9, redshifted to frequency ν = 142.04 MHz. Our Galaxy will also be producing hydrogen recombination radiation. What are the frequencies and n values of the nα transition just above, and just below, 142.04 MHz? (c) Suppose th ...
