Impact of relativistic effects on galaxy clustering future measurements

, 2022
reservedGalaxy clustering measurements are one of the main targets for future cosmological surveys. Such surveys will probe large cosmological volumes, which will require the inclusion of relativistic effects in order to provide a robust and reliable ...

Axiomatizing relativistic dynamics without conservation postulates [PDF]

, 2008
A part of relativistic dynamics (or mechanics) is axiomatized by simple and purely geometrical axioms formulated within first-order logic. A geometrical proof of the formula connecting relativistic and rest masses of bodies is presented, leading up to a ...

Why the Big Bang Singularity does not Help the Kalam Cosmological Argument for Theism [PDF]

, 2007
The Big Bang singularity provides little or no evidence for creation in the finite past and hence for theism. Whether one dismisses singularities or takes them seriously, physics licenses no first moment of (space-)time.

CHEX-MATE: Relationship between X-ray and millimetre inferences of galaxy cluster temperature profiles

Astronomy & Astrophysics
Thermodynamic profiles from X-ray and millimetre observations of galaxy clusters are often compared under the simplifying assumptions of a smooth, spherically symmetric intracluster medium.

Transverse Velocities in Real-Time Cosmology: Position Drift in Relativistic N-Body Simulations

The Open Journal of Astrophysics
The era of real-time cosmology has begun. It is now possible to directly measure the apparent drift of high-redshift astronomical sources across the sky $\textit{in real time}$.

The natural science of cosmology

, 2014
The network of cosmological tests is tight enough now to show that the relativistic Big Bang cosmology is a good approximation to what happened as the universe expanded and cooled through light element production and evolved to the present.

In the hyperbolic theory of special relativity is space also hyperbolic?

In the hyperbolic theory of special relativity the space of velocities, the kinematic space, is hyperbolic of radius of negative curvature c the velocity of light. Space itself could be either Euclidean or hyperbolic.

Dust, Time, and Symmetry [PDF]

, 2004
Two symmetry arguments are discussed, each purporting to show that there is no more room in general relativistic cosmology than in Minkowski spacetime for a preferred division of spacetime into instants of time.
