Observations of Extreme ICME Ram Pressure Compressing Mercury's Dayside Magnetosphere to the Surface
Réka M. Winslow, Noé Lugaz, Lydia Philpott +6
Mercury's magnetosphere is known to be affected by enhanced ram pressures and magnetic fields inside interplanetary coronal mass ejections (ICMEs). Here we report detailed observat…
Particle simulations in causal set theory
Lydia Philpott
Models of particle propagation in causal set theory are investigated through simulations. For the swerves model the simulations are shown to agree with the expected continuum diffu…
Polarization Diffusion from Spacetime Uncertainty
Carlo Contaldi, Fay Dowker, Lydia Philpott
A model of Lorentz invariant random fluctuations in photon polarization is presented. The effects are frequency dependent and affect the polarization of photons as they propagate t…
Extending the Planetary Mass Function to Earth Mass by Microlensing at Moderately High Magnification
Fumio Abe, Charlotte Airey, Ellen Barnard +10
A measurement by microlensing of the planetary mass function of planets with masses ranging from 5M_E to 10M_J and orbital radii from 0.5 to 10 AU was reported recently. A strategy…
Causal Set Phenomenology
Lydia Philpott
Central to the development of any new theory is the investigation of the observable consequences of the theory. In the search for quantum gravity, research in phenomenology has bee…
Energy-momentum diffusion from spacetime discreteness
Fay Dowker, Lydia Philpott, Rafael Sorkin
We study potentially observable consequences of spatiotemporal discreteness for the motion of massive and massless particles. First we describe some simple intrinsic models for the…
