This page serves as a repository for the public outreach animations and movies that I have worked on for both scientific and public talks.  Many of these were developed in coordination with the Northwestern Visualization team, a fantastic group that converts scientific data and concepts into meaningful visualizations.

You are more than welcome to download and use any of these visualizations in any scientific talks or presentations, as long as you mention me (or the Northwestern Viz team).  If you want to use the visualizations in anything else (e.g. a film or other production), please contact me first.  I’ve put a “Credit – …” line above every movie.

NOTE: Some of these movies have not been uploaded from the previous site.  For now, you can access them there.

Gravitational Wave Movies

These movies demonstrate the transition from the Newtonian theory of gravitation to Einstein’s General Relativity.

First we show two objects (e.g. a binary black hole) orbiting around one another as predicted by Newton: an orbit in a fixed spacetime.

Then we show the same orbit, but with the curvature of spacetime, as predicted by Einstein

Finally, we show the same relativistic orbit, but with the emission of gravitational waves.

Here, we show what the spin vectors of a binary look like, as we consider spins that are aligned with the orbital angular momentum, in the orbital plane, and anti-aligned with the orbital direction.  The right plot shows what happens to the gravitational waveform for different spins.

Gravitational Wave Cartoons

[wpvideo ylrytfHj w=220] [wpvideo LjBVoiRK w=220] [wpvideo DmbtAHUS w=220]

A series of cartoons showing the effect on a grid of particles of a passing gravitational wave, and the effect of a gravitational wave on a circle of particles with a LIGO-style detector and a LISA-style detector.

Globular Cluster Movies

[wpvideo eIDzkCAz]

A beautiful simulation of a core of black holes inside a globular cluster, as modeled by an early version of RAPID.  This movie follows the dynamics of 60 black holes and 500 stars in the core, until two black holes are combined to form a black hole binary.

An edited version of the same movie, accelerated to show the formation of the binary black hole.

A movie, created using World Wide Telescope, showing two galactic globular clusters.  The movie starts by zooming in to M22, the first globular discovered, and then sweeps down the southern hemisphere to zoom in on 47 Tuc.

Two scattering tests, generated with John Fregeau’s Fewbody code that shows typical encounters in a cluster.  The top movie shows a standard Newtonian between a binary and a single star, while the bottom movie shows the same interaction with relativistic corrections, including a merger between two of the components due to gravitational waves.

I was invited to give a talk at TEDx Northwestern in April of 2016.  Check it out!
