Great talk from Lia Medeiros on the event horizon telescope results! Black hole shadows were not something I had thought much about before, it kinda feels like the Universe is putting on a shadow puppet show 🕳️💫 @ioppublishing.bsky.social

It's going to be one of those days... Anyone able to help me fix the mess I made on the supercomputer with apptainer?

this is fun

Jump scare from page 11 of our paper 👻

We included this derivation so no one else has to endure the pain of doing it themselves, you're welcome world.

THE RESULTS ARE HERE! We mapped the gravitational wave background and found some cool stuff! We found a bright spot in the Southern Hemisphere, with low statistical significance. Is it a statistical anomaly or something more interesting?? Paper links to come

What generates the gravitational waves that make up the background? It is probably supermassive black-hole binaries and/or early Universe physics. We don't know yet but it is likely a combination of both! 💥

It's paper release day tomorrow! Excited to share with you all!

To measure the gravitational wave background we need an exceptionally sensitive instrument - a gravitational wave detector the size of the Galaxy! A pulsar timing array allows us to do this, as we can accurately time pulsars across the Galaxy 💫 How luck are we to have these natural cosmic clocks?🕐

What is the difference between gravitational-wave signals measured by LIGO and pulsar timing arrays? Well lots of things, but mainly the mass of the black holes. This infographic summarises the differences. 👀🕳️💫

How can pulsars be used to detect gravitational waves? Ripples in spacetime affect the path of light!

I'll be posting some fun infographics in the lead up to my paper release on December 3! Follow along so you're ready for the release 🌟 @ozgrav.bsky.social
