We show that under variation of moduli fields φ the first law of black hole thermodynamics becomes dM = κdA 8π +ΩdJ +ψdq+χdp−Σdφ, where Σ are the scalar charges. We also show that the ADM mass is extremized at fixed A, J , (p, q) when the moduli fields take the fixed value φfix(p, q) which depend only on electric and magnetic charges. It follows that the least mass of any black hole with fixed ...

By means of ab-initio calculations on the basis of the FPLAPW method, we compared the energy loss near edge structure (ELNES) of carbon K edges in crystalline phenanthrene and its isomer, anthracene. In these two organic compounds, different non-equivalent carbon atoms can result in distinct K edge spectra due to the different carbon-carbon bond lengths, as a characteristic behavior of the mole...

The interaction of a cosmic string with a four-dimensional stationary black hole is considered. If a part of an infinitely long string passes close to a black hole it can be captured. The final stationary configurations of such captured strings are investigated. A uniqueness theorem is proved, namely it is shown that the minimal 2-D surface Σ describing a captured stationary string coincides wi...

We obtain the coefficients of a new fundamental plane for supermassive black holes at the centers of elliptical galaxies, involving measured central black hole mass and photometric parameters which define the light distribution. The galaxies are tightly distributed around this mass fundamental plane, with improvement in the rms residual over those obtained from the MBH − σ and MBH − L relations...

We study the classical dynamics of a bosonic string in the D–dimensional flat Friedmann–Robertson–Walker and Schwarzschild backgrounds. We make a perturbative development in the string coordinates around a null string configuration; the background geometry is taken into account exactly. In the cosmological case we uncouple and solve the first order fluctuations; the string time evolution with t...

The coherent evolution of an electron hole in a photoionized molecule represents an unexplored facet of charge transfer phenomena occurring in complex systems. Using ultrafast extreme ultraviolet spectroscopy, we investigate the real-time dynamics of an electron hole wave packet created near a conical intersection in CO_{2}. We resolve the oscillation of the electron hole density between σ and ...

The central black-hole masses of a sample of 30 luminous quasars are estimated using Hβ fwhm measurements from a combination of new and previously-published nuclear spectra. The quasar black-hole mass estimates are combined with reverberationmapping measurements for a sample of Seyfert galaxies (Wandel, Peterson & Malkan 1999) in order to study AGN black-hole masses over a wide range in nuclear...
