Direct Acceleration: Cosmic and Exoplanet Synergies
David Erskine, Alex Kim, Eric Linder +10
Direct measurement of acceleration is a key scientific goal for both cosmology and exoplanets. For cosmology, the concept of redshift drift (more than 60 years old by the 2020s) co…
Orbital Angular Momentum (OAM) Vertical-Cavity Surface-Emitting Lasers
Huanlu Li, David Phillips, Xuyang Wang +6
Harnessing the Orbital Angular Momentum (OAM) of light is an appealing approach to developing photonic technologies for future applications in optical communications and high- dime…
Temporal Substepping Scheme for Magnetohydrodynamics with Cell-based Adaptive Mesh Refinement on Staggered Grid
Ilja Honkonen, Riku Jarvinen, David Phillips
We present a new algorithm for numerical magnetohydrodynamics on staggered meshes preserving . Our algorithm is based on the constrained transport method and su…
Infinite intersections of doubling measures, weights, and function classes
Theresa C. Anderson, David Phillips, Anastasiia Rudenko +1
A series of longstanding questions in harmonic analysis ask if the intersection of all prime ``-adic versions" of an object, such as a doubling measure, or a Muckenhoupt or reve…
Using HARPS-N to characterise the long-period planets in the PH-2 and Kepler-103 systems
Sophie C. Dubber, Annelies Mortier, Ken Rice +26
We present confirmation of the planetary nature of PH-2b, as well as the first mass estimates for the two planets in the Kepler-103 system. PH-2b and Kepler-103c are both long-peri…
A splitting method for numerical relativistic magnetohydrodynamics
Serguei Komissarov, David Phillips
We describe a novel splitting approach to numerical relativistic magnetohydrodynamics (RMHD) designed to expand its applicability to the domain of ultra-high magnetisation (high-$Ï…
