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)....
-
Clusters of Galaxies at High Redshift
For a long time, the small number of clusters at z > 0.3 in the Abell survey catalogue and simulations of the standard CDM formation of large scale...
-
Velocity Dispersion Analysis of CNOC Clusters
I present results of the analysis of the internal velocity dispersions,...
-
The Metal Enrichment History of Clusters of Galaxies
The ratio of the total iron mass in the ICM to the total optical luminosity of the cluster (the iron mass-to-light-ratio) is the same for all...
-
Supernovae at High Redshift
Distant supernovae provide a convenient tool for cosmology. As bright beacons with small variation in their peak luminosity Type Ia Supernovae can be...

The Galactic Bulge: Prospects for the VLT
The central bulge of the Galaxy is 100 times closer than the nearest extragalactic bulge, that of M31. Until the era of 100m telescopes arrives, the...

The Old Population of the Magellanic Clouds
The brightest old stars in the LMC are as faint as V=16 (V=16.5 in the SMC). The VLT with UVES or GIRAFFE will provide, for the first time, high...
-
The Stellar Mass Function
Considerable progress has been made recently in more accurately determining the frequency distribution of stellar masses in the critical 0.1 to 1 m...

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 $\alpha$...
