# Gifs

Here are a selection of gifs that I have produced for talks I have given about my research.

Feel free to use them for your own purposes but please give credit where it is due.

## Geodesic strong-field scatter orbits

A selection of scatter geodesics paramterised by the velocity at infinity $v_\infty$ and the impact parameter $b$. The Innermost Stable Circular Orbit (ISCO) is shown for reference.

## Geodesic weak-field scatter orbits

A selection of scatter geodesics paramterised by the velocity at infinity $v_\infty$ and the impact parameter $b$. The Innermost Stable Circular Orbit (ISCO) is shown for reference.

## Sample scatter orbit

A sample scatter geodesics parameterised by $(v_\infty,b)=(0.2,21M)$. The Innermost Stable Circular Orbit (ISCO) is shown for reference.

## Scatter orbit definitions

A graphical representation of the definitions of the impact parameter $b$ and the scatter angle $\delta\varphi$

## Weak-field scatter orbit

A sample scatter geodesic parameterised by $(v_\infty,b)=(0.5,100M)$.

## Strong-field bound orbit.

A sample bound orbit around a Kerr black hole with $(a,p,e,\theta_{\rm inc}) = (0.998, 6, 0.5, \pi/8)$. The trajectory was generated using the KerrGeodesics package of the Black Hole Perturbation Toolkit.

## Weak-field bound orbit

A small portion of the bound orbit of two equal mass compact objects at large separation.

## Radiation gauge string solutions

Graphical representations of the string solutions of the metric perturbation $h$ in radiation gauges. The red line represents the string-like singularity and background colours represent different radiation gauges. *Left*: Full-string solution. *Centre*: Half-string solutions. *Right*: No-string solution.
