The Four–Dimensional Spacetime
Physics theories are made by building mathematical models that correspond to physical systems. General Relativity, the physical theory of...
-
Momentum and Energy Relations
The equations of motion (5.12) for the charged insulating sphere of radius a moving with arbitrary center velocity u(t) can be rewritten in...
-
Boundary Conditions
Most Numerical Relativity simulations are devised to approximate the time evolution of the dynamical fields starting from data given on an initial...

Derivation of Force and Power Equations
The inconsistency between the power and force equations of motion, (2.4) and (2.1) or (2.5), is so surprising that one is tempted to question the...
-
Internal Binding Forces
In Appendix B, we have critically confirmed the evaluation of the self electromagnetic force and power, (3.1) and (3.2), leading to the force and...

Astrophysical Bounds on Planck Suppressed Lorentz Violation
This article reviews many of the observational constraints on Lorentz symmetry violation (LV). We first describe the GZK cuto. and other phenomena...
-
Inflationary Cosmological Perturbations of Quantum-Mechanical Origin
This review article aims at presenting the theory of inflation. We first describe the background spacetime behavior during the slow-roll phase and...
-
Quantum Gravity
It is not clear at all what is the problem in quantum gravity (cf. [3] or [8] for general reviews, written in the same spirit as the present one)....

Discovery of an X-Ray Outburst in an Optically Non-Active Galaxy
The main X-ray and optical properties of a very luminous X-ray outburst source are summarized. The results are: large variability in X-ray emission...

Gamma-Ray Observations of Black Holes: The Prospects of INTEGRAL
In this paper we describe the upcoming European gamma-ray observatory INTEGRAL (International Gamma-Ray Astrophysics Laboratory). This ESA satellite...
-
A Search for the Presence of Bow Shocks around High-Mass X-Ray Binaries
The measured radial velocities, and the recently derived tangential velocities based on Hipparcos observations, have demonstrated that several...

X-Ray Candidates for a Population of Nuclear Cores in Local Group Galaxies
Because of their closeness, the galaxies of the Local Group are an interesting sample for finding weak manifestations of nuclear activity (as is...

Evidence of a Supernova Origin for the Black Hole in GRO J1655-40 (Nova Scorpii 1994)
We report the discovery of a strong overabundance of several $\alpha$...

Observations of Cygnus X-3 in Quiescence in the $2.4 - 12 \mu$ m Range with ISO
We present mid-infrared spectrophotometric and imaging photometric results obtained with ISO on the peculiar X-ray binary Cygnus X-3. The...

Effects of Anisotropy on the Central Dark Mass in NGC 3115. New Results from Integral Field Spectroscopy
We report new results on the stellar kinematics and the mass distribution of the galaxy NGC 3115 based on NIR integral field spectroscopic data....

SINFONI - Galaxy Dynamics at $0^{\prime\prime}\hspace{-0.2cm}.05$ Resolution with the VLT
The SINFONI integral field spectrometer for the VLT will provide nearinfrared spatially resolved spectra at spatial resolutions close to the...

Simultaneous Infrared and mm- Wave Observations of Disc Ejection Events in GRS 1915+105
We have observed in the Galactic X-ray source GRS 1915+105 some of the brightest 20-min quasi-periodic oscillations yet seen, simultaneously at...

Molecular Gas in Nuclei of the Seyfert Galaxies NGC3227 and NGC1068
New subarcsecond data on NGC 3227 and NGC 1068 obtained with the Plateau de Bure millimeter interferometry indicate large enclosed masses and the...

X-Ray Spectra of Neutron Stars vs. Black Holes
This paper gives an overview of the observed X-ray spectra of lowmass X-ray binaries containing a weakly-magnetized neutron star (NS-LMXRB) and those...

Gravitational Lens Diagnosis of Quasar Accretion Disk
We present simulated microlensing light curves of a quasar accretion disk using two canonical accretion disk models. Furthermore, we investigate the...
