We compare the nature of electromagnetic fields and gravitational fields in linearized general relativity. We carry out this comparison both mathematically and visually. In particular, the “lines of force” visualizations of electromagnetism are contrasted with the recently introduced tendex/vortex eigenline technique for visualizing gravitational fields. Specific solutions, visualizations, and comparisons are given for an oscillating point quadrupole source. Among the similarities illustrated…

Useful insights into the complicated physics of gravitational waves can often be drawn from approximations to analogous physics of electromagnetic waves. Here, we present a gravitational form of the…
A Gravitational Aharonov-Bohm Effect, and Its Connection to Parametric Oscillators and Gravitational Radiation
A thought experiment is proposed to demonstrate the existence of a gravitational, vector Aharonov-Bohm effect. We begin the analysis starting from four Maxwell-like equations for weak gravitational…

Recent results provide an analytic expression for the quality factor, or Q, of gravitationally-small gravitational quadrupoles, drawing upon similarities to the Chu limit for electrically-small…
Radiation Reaction of Charged Particles Orbiting a Magnetized Schwarzschild Black Hole
In many astrophysically relevant situations radiation reaction force acting upon a charge can not be neglected and the question arises about the location and stability of circular orbits in such…

Orbital widening due to radiation reaction around a magnetized black hole
Radiation reaction acting on a charged particle moving at a stable circular orbit of a magnetized black hole can lead to the shift of the orbital radius outwards from the black hole. The effect…

Classifying the isolated zeros of asymptotic gravitational radiation by tendex and vortex lines
A new method to visualize the curvature of spacetime was recently proposed. This method finds the eigenvectors of the electric and magnetic components of the Weyl tensor and, in analogy to the field…
Field line motion in classical electromagnetism
We consider the concept of field line motion in classical electromagnetism for crossed electromagnetic fields and suggest definitions for this motion that are physically meaningful but not unique.…
Nonspherical perturbations of relativistic gravitational collapse
It is known that there can be no gravitational, electromagnetic, or scalar field perturbations (except angular momentum) of a Schwarzschild black hole. A gravitationally collapsing star with…

A new approach to general relativity by means of a tetrad or spinor formalism is presented. The essential feature of this approach is the consistent use of certain complex linear combinations of…
Frame-dragging vortexes and tidal tendexes attached to colliding black holes: visualizing the curvature of spacetime.
TLDR
This work introduces tools for visualizing B(jk) (frame-drag vortex lines, their vorticity, and vortexes) and E( jk) and also visualizations of a black-hole horizon's (scalar) vortsicity and tendicity to elucidate the nonlinear dynamics of curved spacetime in merging black- hole binaries.
Visualizing spacetime curvature via frame-drag vortexes and tidal tendexes: General theory and weak-gravity applications
When one splits spacetime into space plus time, the Weyl curvature tensor (vacuum Riemann tensor) gets split into two spatial, symmetric, and trace-free tensors: (i) the Weyl tensor’s so-called…
The topology of symmetric, second-order tensor fields
TLDR
A topological rule is shown that puts a constraint on the topology of Tensor fields defined across surfaces, extending to tensor fields the Poincare-Hopf theorem for vector fields.
Why no shear in “Div, grad, curl, and all that”?
Are there good reasons for the absence of shear and gradients of vectors in the undergraduate curriculum, or have we simply been negligent by not explicitly introducing students to these concepts…
Dynamic Line Integral Convolution for Visualizing Streamline Evolution
TLDR
This article describes a technique for generating animations of time-dependent vector fields where the motion of the streamlines to be visualized is given by a second "motion" vector field.
Imaging vector fields using line integral convolution
TLDR
This approach builds on several previous texture generation and filtering techniques but is unique because it is local, one-dimensional and independent of any predefined geometry or texture.
