It was an honor to present one of Caltech's Everhart Lectures this year, in which I shared some of my thesis work with the broader community. If you want to see it for yourself, it's uploaded here! https://t.co/2zyvQQN3Je

When you look up at the night sky, you're looking out on a universe that is ever evolving: planets orbit, stars twinkle, and black holes collide. Moreover, thanks to @LIGO, we know that the "spacetime fabric" also evolves as gravitational waves ripple through it! 1/13

But who knows! Maybe if we rerun our analysis on the recently-released GWTC-5.0 we'll see more promise... (stay tuned!)

If you want to learn more or if you have any questions, check out the paper on arXiv or feel free to ask me here!

Long overdue, but I'm moving to bluer skies! https://t.co/OQJYSnrWaj

New @NANOGrav paper! We targeted 114 AGN to ask if specific galaxies host supermassive black hole binaries — getting ~2x better constraints. Two sources stood out, so we built a detection protocol. We named them Rohan and Gondor. The beacons are lit!🏔️🏔️🔥

And now you can read all about it in Caltech's press release! https://t.co/OcdM9UIl0u
