In continued celebration of a decade of GW detections, some of the @vanderbilt.edu astrophysicists made this fun explainer video. We had a great time making this; just the right amount of cheesy delivery. My students have already gotten a kick out of it.

Truly wonderful to have you and Barry visit us, Saavik! We all had a great time. Hope you did too!

Vanderbilt, in Nashville.
Where he was also, apparently, a tv weather guy!
I know this thanks to a DELIGHTFUL visit to the Vandy Astro group!
Thanks to @stevertaylor.bsky.social & everyone else, from undergrads to faculty!

My research group (aka VIPER) visited our High Performance Computing facility @vanderbilt.edu. An incredibly impressive operation, and very exciting to see the investments in GPUs for AI and scientific computing. As for the picture below, I just wanted to look cool with some servers... πππ§ͺβοΈπ«πͺ

But it's certainly getting better, and for small optimizations or fixes, it's like super specific stackoverflow thread. Provided it's used to assist or teach, it has utility. But not to replace.

Very honored to have been named a Chancellor Faculty Fellow by Vanderbilt University in recognition of my ongoing drive to push the boundaries of gravitational-wave and multi-messenger astrophysics! (They used a photo of me from 2019 though...π) π§ͺπππͺβοΈπ«

Amazing work from Vanderbilt postdoctoral fellow, Nima Laal. Wonderful to see this published. Answering "what if you searched for everything, everywhere, all at once" in pulsar-timing array gravitational wave searches. A gigantic Gibbs sampling hierarchical fit. ππ§ͺπͺ
