Here is a really nice video that NSF made to help publicize the release of NANOGrav's 15-yr gravitational wave results, where we announced strong evidence for a nHz-frequency gravitational wave background using an array of millisecond pulsars. It (both the video and the project) is super cool! And see if you can guess who did the voiceover...

Based on some questions I had in talks about how we dedisperse pulsar data and why it is harder to detect fast pulsars rather than slow ones, I made these movies: a slow strong pulsar, the same slow pulsar but much fainter (as per a real search), and a weak MSP. Note how much narrower the significance peak (i.e. reduced-chi2) is as a function of Dispersion Measure for the MSP! Here is the python script that made the movies if you are curious.
