The rxte PCA data are used to put\nan upper limit on the broad line component and constrain the hard X-ray\ncontinuum. A strong soft excess below 1 keV is observed in the time-averaged\nHETG spectrum, which can be parameterized with a steep power law or a thermal\nmodel. The flux variability at low energies indicates that the origin of the\nsoft excess cannot be entirely ascribed to the circumnuclear diffuse emission,\ndetected by chandra on scales of 20-30 arcsec (22-33 kpc). A narrow (sigma<90\neV) Fe Kalpha line (with EW< 100 eV) is observed by the chandra HEG. Similar\nvalues for the line parameters are measured by the rxte PCA, suggesting that\nthe contribution from a broad line component is negligible. The fact that the\nexposure is split into two observations taken three days apart allows us to\ninvestigate the spectral and temporal evolution of the source on different\ntimescales. Significant flux variability associated with spectral changes is\nobserved on timescales of hours and days.

At low photon fluxes this\nbehavior reflects the time and energy entanglement between the down-converted\nphotons. However, two-photon interactions such as two-photon absorption (TPA)\nand sum-frequency generation (SFG) can exhibit such a behavior even at high\npower levels, as long as the final state (i.e. the atomic level in TPA, or the\ngenerated light in SFG) is narrowband enough. This behavior does not depend on\nthe squeezing properties of the light, is insensitive to linear losses, and has\npotential applications. In this paper we describe analytically this behavior\nfor travelling-wave down-conversion with continuous or pulsed pumping, both for\nhigh- and low-power regimes. For this we derive a quantum-mechanical expression\nfor the down-converted amplitude generated by an arbitrary pump, and formulate\noperators that represent various two-photon interactions induced by broadband\nlight.

However, the derived parameters are often extreme, both in\nterms of the underlying spacetime and the reflection geometry, and these models\nrequire that the disc is far from hydrostatic equilibrium. An alternative model\nuses similarly partially ionised, velocity smeared material but seen in\nabsorption, though again the derived velocities are extreme, requiring magnetic\ndriving (in the jet?) rather than a simple line driven disc wind. We find that\nwhile both models give comparably good fits to XMM--Newton data, we favour the\nabsorption model as, unlike reflection, all the derived spectral indices are\nsoft. This is as expected by analogy with the correspondingly high mass\naccretion rate stellar mass black holes. Furthermore, these X-ray spectra are\nconsistent with a one--to--one mapping between AGN type and spectral state,\nwith NLS1\'s having softer spectra corresponding to the very high state, while\nthe broad line AGN have Gamma~2 as expected for the high/soft state.

This does\nnot always show that the disc in NLS1\'s contributes less than 80 per cent of\nthe total power, as expected for a very high state. We suggest that this is an\nartifact of the standard disc models used to determine the disc luminosity in\nour fits.

The results show the percentage of planetesimals that\nfall on the star.

It is shown that, if the zero point energies for\nthe cosmic microwave background and for all the rest of the universe that is\nnot cosmic microwave background are introduced into this model as two entities,\ntheir separate values appear within this theory in the form of a numerical\ndifference.

Consequently, although the two\nzero point energies may be large, their difference can give the known small\ndark energy value from cosmology for dark energy density. Issues relating to\ninterpretation, calculation and measurement associated with this result and an\ninterpretation of dark energy as a measure of polarisation of the vacuum are\ndiscussed.

Both hydrodynamic\ninstabilities in combination stretch the advection time of matter through the\nneutrino-heating layer and thus enhance the neutrino energy deposition in\nsupport of the neutrino-driven explosion mechanism. A rapidly contracting and\nmore compact nascent NS turns out to be favorable for explosions, because the\naccretion luminosity and neutrino heating are larger and the growth rate of the\nSASI is higher. Moreover, we show that the oscillation period of the SASI and a\nvariety of other features in our simulations agree with estimates for the\nadvective-acoustic cycle (AAC), in which perturbations are carried by the\naccretion flow from the shock to the neutron star and pressure waves close an\namplifying global feedback loop.

The cluster has one multiply imaged system\nconstituted by a double gravitational arc.\n  We have performed a parametric strong lensing mass reconstruction using NFW\ndensity profiles to model the cluster potential. We also included perturbations\nfrom 23 galaxies, modeled like elliptical singular isothermal sphere, that are\napproximately within 1\'x1\' around the cluster center.

The\nresults from the strong lensing model shows the complex structure in this\ncluster, the asymmetry and the elongation in the mass distribution, and are\nconsistent with previous spectrophotometric results that indicate that the\ncluster has a bimodal mass distribution.

Remarkably, the model possesses an exact solution\nwhen tuned to a special manifold in its parameter space known as the Toulouse\nlimit. We use the Toulouse limit to exactly calculate the adiabatically pumped\nspin current in the Kondo regime. In the absence of both potential scattering\nand a voltage bias, the instantaneous charge current is strictly zero for a\ngeneric Kondo model. However, a nonzero spin current can be pumped through the\nsystem in the presence of a finite magnetic field, provided the spin couples\nasymmetrically to the two leads. Tunneling through a Kondo impurity thus offers\na natural mechanism for generating a pure spin current. We show, in particular,\nthat one can devise pumping cycles along which the average spin pumped per\ncycle is closely equal to $\\hbar$. By analogy with Brouwer\'s formula for\nnoninteracting systems with two driven parameters, the pumped spin current is\nexpressed as a geometrical property of a scattering matrix. However, the\nrelevant %Alex: I replaced topological with geometrical in the sentence above\nscattering matrix that enters the formulation pertains to the Majorana fermions\nthat appear at the Toulouse limit rather than the physical electrons that carry\nthe current. These results are obtained by combining the nonequilibrium Keldysh\nGreen function technique with a systematic gradient expansion, explicitly\nexposing the small parameter controlling the adiabatic limit.\n', '[{\"version\":\"v1\",\"created\":\"Mon, 23 Apr 2007 14:21:07 GMT\"},{\"version\":\"v2\",\"created\":\"Tue, 13 Nov 2007 09:22:14 GMT\"}]', '2009-11-13', '[[\"Schiller\",\"Avraham\",\"\"],[\"Silva\",\"Alessandro\",\"\"]]'),
