The nature of the super-massive black hole candidates in galactic nuclei can be tested by ana-lyzing the profile of the Ka iron line observed in their X-ray spectrum. In this paper, we consider the possibility that the ...

An approach is presented for calculating thermoelastic generation of ultrasound in a metal plate exposed to nanosecond pulsed laser heating, sufficient to cause melting but not ablation. Detailed consideration is given to ...

The water-based liquid scintillator (WbLS) is a new material currently under development. It is based on the idea of dissolving
the organic scintillator in water using special surfactants. This material strives to achieve ...

We report on absolute line strength measurements of P(1), R(0) and R(1) singlet lines in the 3:3 μm ν3 (C–H stretching) band of methane 12CH4 at referencetemperature T = 296 K. Line strength measurements are performed at ...

We investigate superfluidity, and the mechanism for creation of quantized vortices, in the relativistic regime.The general framework is a nonlinear Klein-Gordon equation in curved spacetime for a complex scalar field, whose ...

A (3+1)-dimensional asymptotically at Kerr black hole angular speed + can be used to de ne an e ective spring constant, k = m2 +. Its maximum value is the Schwarzschild
surface gravity, k = , which rapidly weakens as ...

Very accurate variational calculations of the complete pure vibrational spectrum of the ditritium (T2) molecule are performed within the framework where the Born-Oppenheimer approximation is not assumed. After separating ...

We study the complete gravitational collapse of a class of inhomogeneous perfect fluid models obtained by introducing small radial perturbations in an otherwise homogeneous matter cloud. The key feature that we assume for ...

We study the homogeneous gravitational collapse of a spherical cloud of matter in a super-renormalizable and asymptotically free theory of gravity. We nd a picture that di ers substantially from the classical scenario. ...

Abstract While not reported in the literature, by employing highly oriented, semi-insulating, thin-film CdS as test material, we present the observation of the intrinsic photoluminescence Stokes shift in a semiconductor. ...

We show that, in principle, a slowly evolving gravitationally collapsing perfect fluid cloud can asymptotically settle to a static spherically symmetric equilibrium configuration with a naked singularity at the center. We ...

We derive the dynamics of the gravitational collapse of a homogeneous and spherically symmetric cloud in a classical set-up endowed with a topological sector of gravity and a non-minimal coupling to fermions. The effective ...

The spin measurement of black holes has important implications in physics and astrophysics. Regardless of the specific technique to estimate the black hole spin, all the current approaches assume that the space-time geometry ...

In general relativity, gravitational collapse of matter fields ends with the formation
of a spacetime singularity, where the matter density becomes infinite and standard physics breaks down. According to the weak cosmic ...
