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... 🚀🔭🧪⚛️💫🪐

A fun and productive LISA Science Team meeting at NASA Goddard! Our team is tasked with stewarding the mission toward maximizing its science outcomes. We’re really digging into our various tasks now; we even got to see prototypes of some of the laser and optics assembles. 🧪⚛️🔭

TENURE UNLOCKED 🎓🚀🧪⚛️🔭

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. 🔭🧪🪐

Professor Sarah Vigeland of UWM gives an invited plenary in the Kavli Special Session at APS. Fantastic talk! @nanograv.bsky.social @dgrav.org

Xavi Siemens gets his APS Fellow on! Highly deserved and great to see! @nanograv.bsky.social @dgrav.org

My student Levi Schult absolutely smashed their talk today on comparing different detection techniques for the first single GW signal expected to be found by PTAs. @nanograv.bsky.social @dgrav.org

Dr Nima Laal, postdoctoral fellow at Vanderbilt in my group, tells us all about sampling data covariance matrices with Inverse Wishart distributions— everything everywhere all at once! @nanograv.bsky.social @dgrav.org

My student William Lamb @astrolamb.bsky.social updates us on some ambitious analytic calculations he’s been doing to model discrete binary and cosmic variance in the ensemble distribution of the stochastic GW background. @nanograv.bsky.social @dgrav.org

Great talk by my student Kyle Gersbach on directional power-based searches for supermassive binary black holes in PTA data! @dgrav.org
