Supermassive Black Holes: modelling strongly and weakly magnetised misaligned accretion disks
Joshua Samuel Stanway, Cora Prather, Derek Ward-Thompson +3
In this paper, we carry out a numerical study of misaligned accretion disks around spinning supermassive black holes. Here, we conduct a parameter survey covering a range of initia…
New estimates of the spin and accretion rate of the black hole M87*
Michael Drew, Joshua S. Stanway, Brett A. Patterson +2
In this paper we use the imaging results of M87* from the EHT to calculate the rotational velocity of the inner edge of the accretion disk and find a value of 0.14c. We then…
Scalar Pre-potentials for Spinor and Tensor Fields on Spacetime
Robin W. Tucker, Timothy J. Walton
We review a technique for solving a class of classical linear partial differential systems of relevance to physics in Minkowski spacetime. All the equations are amenable to analysi…
A new paradigm for the dynamics of the early Universe
Robin W. Tucker, Timothy J. Walton, Manuel Arrayás +1
This paper invokes a new mechanism for reducing a coupled system of fields (including Einstein's equations without a cosmological constant) to equations that possess solutions exhi…
Chirality in Gravitational and Electromagnetic Interactions with Matter
Robin W. Tucker, Timothy J. Walton
It has been suggested that single and double jets observed emanating from certain astrophysical objects may have a purely gravitational origin. We discuss new classes of pulsed gra…
On Gravitational Chirality as the Genesis of Astrophysical Jets
Robin W. Tucker, Timothy J. Walton
It has been suggested that single and double jets observed emanating from certain astrophysical objects may have a purely gravitational origin. We discuss new classes of plane-fron…
Classical Dynamics of Free Electromagnetic Laser Pulses
S. Goto, R. W. Tucker, T. J. Walton
We discuss a class of exact finite energy solutions to the vacuum source-free Maxwell field equations as models for multi- and single cycle laser pulses in classical interaction wi…
Axionic suppression of plasma wakefield acceleration
D. A. Burton, A. Noble, T. J. Walton
Contemporary attempts to explain the existence of ultra-high energy cosmic rays using plasma-based wakefield acceleration deliberately avoid non-Standard Model particle physics. Ho…
The Dynamics of Compact Laser Pulses
S. Goto, R. W. Tucker, T. J. Walton
We discuss the use of a class of exact finite energy solutions to the vacuum source-free Maxwell equations as models for multi- and single cycle laser pulses in classical interacti…
Aspects of Quantum Energy and Stress in Inhomogeneous Unbounded Dielectric Continua
S. Goto, R. W. Tucker, T. J. Walton
This article addresses a number of issues associated with the problem of calculating contributions from the electromagnetic quantum induced energy and stress in a stationary materi…
On the computation of Casimir stresses in open media and Lifshitz theory
Shin-itiro Goto, Robin W Tucker, Timothy J Walton
A classification of the electromagnetic modes on open and closed spatial domains containing media with piecewise homogeneous permittivities is used to facilitate the derivation of…
Numerical Regularization of Electromagnetic Quantum Fluctuations in Inhomogeneous Dielectric Media
Shin-itiro Goto, Alison C. Hale, Robin W. Tucker +1
Electromagnetic Casimir stresses are of relevance to many technologies based on mesoscopic devices such as MEMS embedded in dielectric media, Casimir induced friction in nano-machi…
Quantum Electromagnetic Fluctuations in Inhomogeneous Dielectric Media
Shin-itiro Goto, Robin W. Tucker, Timothy J. Walton
A new mathematical and computational technique for calculating quantum vacuum expectation values of energy and momentum densities associated with electromagnetic fields in bounded…
The Electrodynamics of Inhomogeneous Rotating Media and the Abraham and Minkowski Tensors II: Applications
Shin-itiro Goto, Robin W. Tucker, Timothy J. Walton
Applications of the covariant theory of drive-forms are considered for a class of perfectly insulating media. The distinction between the notions of "classical photons" in homogene…
The Electrodynamics of Inhomogeneous Rotating Media and the Abraham and Minkowski Tensors I: General Theory
Shin-itiro Goto, Robin W. Tucker, Timothy J. Walton
This is paper I of a series of two papers, offering a self-contained analysis of the role of electromagnetic stress-energy-momentum tensors in the classical description of continuo…
An Intrinsic Approach to Forces in Magnetoelectric Media
R. W. Tucker, T. J. Walton
This paper offers a conceptually straightforward method for the calculation of stresses in polarisable media based on the notion of a drive form and its property of being closed in…
