“…Therefore the problem of the different coupling of different spectroscopic methods to density fluctuations arising in the theoretical analysis of the fast β regime may be circumvented and the situation may be of similar simplicity as for ionic glass-formers [13,20]. Currently, an investigation of the glycerol-LiCl system at higher frequencies, both with dielectric spectroscopy and with neutron scattering, is under way and the results will be reported in a forthcoming paper [31].…”

“…Compared to earlier work on LiCl dissolved in glycerol [23], the present investigation covers a significantly broader temperature (204 K < T < 363 K) and frequency (10 Hz < ν < 1.8 GHz) range and provides information for a larger number of different ion concentration levels. The present work exclusively deals with the α-relaxation dynamics; work on the investigation of the fast β-dynamics currently is in progress and the results will be provided in a forthcoming article, also including information on the Johari-Goldstein process [31] Here we address the question how the ionic dynamics, accessible by the modulus evaluation, and the reorientational (and thus structural) one develop with increasing concentration level. In addition, we provide information on the dependence of the dc conductivity on ion content.…”

Dielectric and conductivity relaxation in mixtures of glycerol with LiCl

We report a thorough dielectric characterization of the alpha relaxation of glass-forming glycerol with varying additions of LiCl. Nine salt concentrations from 0.1 to 20mol% are investigated in a frequency range of 20Hz-3GHz and analyzed in the dielectric loss and modulus representation. Information on the dc conductivity, the dielectric relaxation time (from the loss) and the conductivity relaxation time (from the modulus) is provided. Overall, with increasing ion concentration, a transition from reorientationally to translationally dominated behavior is observed and the translational ion dynamics and the dipolar reorientational dynamics become successively coupled. This gives rise to the prospect that, by adding ions to dipolar glass formers, dielectric spectroscopy may directly couple to the translational degrees of freedom determining the glass transition, even in frequency regimes where usually strong decoupling is observed.

“…In an idealised homogeneous jet the velocity profile in the direction perpendicular to the jet axis scales linearly with expansion and so small sections of the jet maintain a constant perpendicular velocity and are effectively ballistic. Whilst these arguments are based on an idealised situation, a conical jet with an opening angle θopeningγ bulk > 1 is not causally connected laterally and analytic work by Zakamska et al (2008) found that far away from the black hole a conical jet will always become causally disconnected and this seems to be the case for jet parameters inferred from observations of GRBs Kohler & Begelman (2012). Work reproducing the large scale observed emission and polarisation of FRI jets using MHD models by Laing & Bridle (2004) found that jets were better described by non-adiabatic jets as opposed to adiabatic jets.…”

In this paper we develop the jet model of Potter & Cotter (2012) to include a magnetically dominated accelerating parabolic base transitioning to a slowly decelerating conical jet with a geometry set by recent radio observations of M87. We conserve relativistic energy-momentum and particle number along the jet and calculate the observed synchrotron emission from the jet by calculating the integrated line of sight synchrotron opacity through the jet in the rest frame of each section of plasma. We calculate the inverse-Compton emission from synchrotron, CMB, accretion disc, starlight, broad line region, dusty torus and narrow line region photons by transforming into the rest frame of the plasma along the jet.We fit our model to simultaneous multi-wavelength observations of the Comptondominant FSRQ type blazar PKS0227-369, with a jet geometry set by M87 and an accelerating bulk Lorentz factor consistent with simulations and theory. We investigate models in which the jet comes into equipartition at different distances along the jet and equipartition is maintained via the conversion of jet bulk kinetic energy into particle acceleration. We find that the jet must still be magnetically dominated within the BLR and cannot be in equipartition due to the severe radiative energy losses. The model fits the observations, including radio data, very well if the jet comes into equipartition outside the BLR within the dusty torus (1.5pc) or at further distances (34pc). The fits require a high power jet with a large bulk Lorentz factor observed close to the line of sight, consistent with our expectations for a Compton-dominant blazar. We find that our fit in which the jet comes into equipartition furthest along the jet, which has a jet with the geometry of M87 scaled linearly with black hole mass, has an inferred black hole mass close to previous estimates. This implies that the jet of PKS0227 might be well described by the same jet geometry as M87.
