Constraints on quantum gravity and the photon mass from gamma ray bursts
Deaglan J. Bartlett, Harry Desmond, Pedro G. Ferreira +1
Lorentz invariance violation in quantum gravity (QG) models or a nonzero photon mass, , would lead to an energy-dependent propagation speed for photons, such that photons of d…
Constraints on Equivalence Principle Violation from Gamma Ray Bursts
Deaglan J. Bartlett, Dexter Bergsdal, Harry Desmond +2
Theories of gravity that obey the Weak Equivalence Principle have the same Parametrised Post-Newtonian parameter for all particles at all energies. The large Shapiro time delay…
Perturbations and the Future Conformal Boundary
A. N. Lasenby, W. J. Handley, D. J. Bartlett +1
The concordance model of cosmology predicts a universe which finishes in a finite amount of conformal time at a future conformal boundary. We show that for particular cases we stud…
Improved cosmological fits with quantized primordial power spectra
D. J. Bartlett, W. J. Handley, A. N. Lasenby
We observationally examine cosmological models based on primordial power spectra with quantized wavevectors. Introducing a linearly quantized power spectrum with $k_0=3.225\times10…
Calibrating galaxy formation effects in galactic tests of fundamental physics
Deaglan J. Bartlett, Harry Desmond, Pedro G. Ferreira
Galactic scale tests have proven to be powerful tools in constraining fundamental physics in previously under-explored regions of parameter space. The astrophysical regime which th…
