Large-scale cosmic ray anisotropies with 19 years of data from the Pierre Auger Observatory

The Pierre Auger Collaboration, A. Abdul Halim, P. Abreu +355

Results are presented for the measurement of large-scale anisotropies in the arrival directions of ultra-high-energy cosmic rays detected at the Pierre Auger Observatory during 19…

New Evidence of the Azimuthal Alignment of Quasars Spin vector in the LQG U1.28, U1.27, U1.11, Cosmologically Explained

Reinoud Jan Slagter

There is observational evidence that the spin axes of quasars in large quasar groups are correlated over hundreds of Mpc. This is found in the radio sector as well as in the optica…

On the Azimuthal Alignment of Quasars Spin Vector in Large Quasar Groups and Cosmic Strings

Reinoud Jan Slagter

We find evidence of the alignment of the azimuthal angle of the spin vectors of quasars in large quasar groups of different redshift. This effect is probably of cosmological origin…

On the dynamical 4D BTZ black hole solution in conformally invariant gravity

Reinoud Jan Slagter

We review the (2+1)-dimensional Baunados-Teitelboim-Zanelli black hole solution in conformally invariant gravity, uplifted to (3+1)-dimensional spacetime. As matter content we use…

On the BTZ Black Hole and the Spinning Cosmic String

Reinoud J. Slagter, Jebin Larosh

We reviewed the Ba\u nados-Teitelboim-Zanelli (BTZ) black hole solution in connection with the spinning string solution. We find a new exact solution, which can be related to the $…

Cosmic Strings in Conformal Gravity

Reinoud Jan Slagter

We investigate the spacetime of a spinning cosmic string in conformal invariant gravity, where the interior consists of a gauged scalar field. We find exact solutions of the exteri…

Alignment of Quasar Polarizations on Large Scales Explained by Warped Cosmic Strings

Reinoud Jan Slagter

The recently discovered alignment of quasar polarizations on very large scales could possibly explained by considering cosmic strings on a warped five dimensional spacetime. Compac…

Evolution and Dynamics of a Matter creation model

Supriya Pan, Jaume de Haro, Andronikos Paliathanasis +1

In a flat Friedmann-Lema\^ıtre-Robertson-Walker (FLRW) geometry, we consider the expansion of the universe powered by the gravitationally induced `adiabatic' matter creation. To de…

A New Fate of a Warped 5D FRW Model with a U(1) Scalar Gauge Field

Reinoud Jan Slagter, Supriya Pan

If we live on the weak brane with zero effective cosmological constant in a warped 5D bulk spacetime, gravitational waves and brane fluctuations can be generated by a part of the 5…

Nonlinear gravitational waves as dark energy in warped spacetimes

Reinoud Jan Slagter

On a warped five-dimensional Friedmann-Lema\^ıtre-Robertson-Walker(FLRW) spacetime, dark energy can be induced by a U(1) scalar-gauge field on the brane. We consider a zero effecti…

On Closed Timelike Curves and Warped Brane World Models

Reinoud Jan Slagter

At first glance, it seems possible to construct in general relativity theory causality violating solutions. The most striking one is the Gott spacetime. Two cosmic strings, approac…

Warped Self-Gravitating U(1) Gauge Cosmic Strings in 5D

R. J. Slagter, D. Masselink

We present the "classical" Nielsen-Olesen vortex solution on a warped five dimensional space time, where we solved the effective four-dimensional equations from the five-dimensiona…

A 5-Dimensional Spherical Symmetric Solution in Einstein-Yang-Mills Theory With Gauss-Bonnet Term

R. J. Slagter

We present a numerical solution on a 5-dimensional spherically symmetric space time, in Einstein-Yang-Mills-Gauss-Bonnet theory using a two point boundary value routine. It turns o…

Melvin solution with a dilaton potential

Eugen Radu, Reinoud J. Slagter

We find new Melvin-like solutions in Einstein-Maxwell-dilaton gravity with a Liouville-type dilaton potential. The properties of the corresponding solution in Freedman-Schwarz gaug…

High-Frequency Gravitational Waves from Spinning Non-Abelian Cosmic-Strings

Reinoud J. Slagter

We investigated the SU(2) Einstein-Yang-Mills system on a time-dependent non-diagonal cylindrical symmetric space-time. From the numerical investigation, wave-like solutions are fo…
