Resonance phenomena in kink antikink collisions within higher order shifted periodic high order models
Teboho Abram Moloi
We investigate kink antikink collisions in higher order scalar field theories described by the higher order models and their shifted periodic extensions. Both classes of models pos…
Thermodynamic coefficients in third-order relativistic fluid dynamics
Teboho Abram Moloi, Azwinndini Muronga
We developed the third-order hydrodynamic equations using relativistic extended thermodynamics of gases with 14 independent fields. The resulting fluid equations are based on the r…
Probing beyond-Horndeski gravity on ultra-large scales
Didam Duniya, Teboho Moloi, Chris Clarkson +4
The beyond-Horndeski gravity has recently been reformulated in the dark energy paradigm - which has been dubbed, Unified Dark Energy (UDE). The evolution equations for the given UD…
Testing General Relativity with the Doppler magnification effect
Sambatra Andrianomena, Camille Bonvin, David Bacon +4
The apparent sizes and brightnesses of galaxies are correlated in a dipolar pattern around matter overdensities in redshift space, appearing larger on their near side and smaller o…
