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. 🧪⚛️🔭

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. 🔭🧪🪐 journals.aps.org/prd/abstract...

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

GW localization region, showing enclosed galaxies along with the injected source.

GW localization area for a binary source as a function of proximity to pulsars on the sky.

GW localization area as a function of the binary source chirp mass, showing the importance of modeling the full signal rather than just the Earth-term component.
