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. We also\nuse the simultaneous OM data to derive the ratio of disc to total accretion\npower which is another tracer of spectral state in X-ray binaries. 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 disc seen in the very high state of black hole binaries is often\nobserved to be distorted from the standard shape, and a similar effect in\nNLS1\'s could recover the correspondance between black hole binary spectral\nstate and AGN type.\n', '[{\"version\":\"v1\",\"created\":\"Mon, 23 Apr 2007 10:43:00 GMT\"},{\"version\":\"v2\",\"created\":\"Tue, 14 Aug 2007 13:52:53 GMT\"}]', '2009-11-13', '[[\"Middleton\",\"M.

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.

We\ncompare three outflow models: No outflows, a \"constant wind\" (cw) model that\nemulates the popular Dekel & Silk (1986) scenario, and a ``momentum-driven\nwind\" (vzw) model. We find that only the vzw scaling reproduces the observed\nz~2 MZR\'s slope, amplitude, and scatter. Comparing our fully three-dimensional\nsimulations with a simple one-zone chemical evolution model, we find that the\nMZR can be understood in terms of three parameters: (1) The equilibrium\nmetallicity Z_eq=y*SFR/ACC (where y=true yield), reflecting the enrichment\nbalance between star formation rate SFR and gas accretion rate ACC; (2) the\ndilution time t_d=M_g/ACC, representing the timescale for a galaxy to return to\nZ_eq after a metallicity-perturbing interaction; and (3) the blowout mass\nM_blowout, which is the galaxy stellar mass above which winds can escape its\nhalo. When outflows with mass loading factor MLF are present, galaxies below\nM_blowout obey Z_eq = y/(1+MLF), while above M_blowout, Z_eq->y. Our cw model\nhas M_blowout ~ 10^10 M_sun, which yields a sharp upturn in the MZR above this\nscale and a flat MZR with large scatter below it, in strong disagreement with\nobservations. Our vzw model reproduces the observed Z_g \\propto M_*^0.3 because\nZ_eq \\propto MLF^-1 \\propto M_*^1/3 when MLF >> 1 (i.e. at low masses). The\nflattening of the MZR at M_* > 10^10.5 M_sun observed by Tremonti et al.

We probe the effect of turbulent diffusion on the chemistry at the\ninterface between a cold neutral medium (CNM) cloudlet and the warm neutral\nmedium (WNM). Methods. We perform moving grid, multifluid, 1D, hydrodynamical\nsimulations with chemistry including thermal and chemical diffusion. The\ndiffusion coefficients are enhanced to account for turbulent diffusion. We\npost-process the steady-states of our simulations with a crude model of\nradiative transfer to compute line profiles. Results. Turbulent diffusion\nspreads out the transition region between the CNM and the WNM. We find that the\nCNM slightly expands and heats up: its CH and H$_2$ content decreases due to\nthe lower density. The change of physical conditions and diffusive transport\nincrease the H$^+$ content in the CNM which results in increased OH and H$_2$O.\nDiffusion transports some CO out of the CNM. It also brings H$_2$ into contact\nwith the warm gas with enhanced production of CH$^+$, H$_3^+$, OH and H$_2$O at\nthe interface. O lines are sensitive to the spread of the thermal profile in\nthe intermediate region between the CNM and the WNM. Enhanced molecular content\nat the interface of the cloud broadens the molecular line profiles and helps\nexciting transitions of intermediate energy. The relative molecular yield are\nfound higher for bigger clouds. Conclusions. Turbulent diffusion can be the\nsource of additional molecular production and should be included in chemical\nmodels of the interstellar medium (ISM). It also is a good candidate for the\ninterpretation of observational problems such as warm H$_2$, CH$^+$ formation\nand presence of H$_3^+$.\n', '[{\"version\":\"v1\",\"created\":\"Tue, 24 Apr 2007 09:53:59 GMT\"}]', '2009-11-13', '[[\"Lesaffre\",\"P.\",\"\"],[\"Gerin\",\"M.\",\"\"],[\"Hennebelle\",\"P.\",\"\"]]'),

As a novelty\nan explicit quark chemical potential and N_f-dependence in the Polyakov loop\npotential is proposed by using renormalization group arguments. The behavior of\nthe Polyakov loop as well as the chiral condensate as function of temperature\nand quark chemical potential is obtained by minimizing the grand canonical\nthermodynamic potential of the system.
