Exciting news: The UltracoolSheet v2.0.0 is live! Explore photometry, astrometry, spectroscopy, and multiplicity data for all your favorite LTY planetary-mass objects and brown dwarfs. zenodo.org/records/105732…

I experiment with using a large PSF library to improve the performance of Reference Star Differential Imaging with Keck/NIRC2! I have provided raw images, PSF-subtracted images, and contrast curves for ~4 years worth of survey observations on Zenodo. arxiv.org/abs/2408.14268

This must have been the craziest 1 month of grad school so far! ✅Passed Caltech Astro’s 1st year qualifying exam ✅Designed and observed 2.5 nights for my first PI program with the CHARA interferometer ✅Submitted Keck 2025A proposal ✅Led a JWST Cycle 4 proposal

The biggest astronomy story of the day is the announcement of a giant exoplanet candidate near the habitable zone of Alpha Centauri A. Was only detected in 1 of 3 JWST observations though. arxiv.org/abs/2508.03814

While not yet confirmation, the fact that JWST sees a planet candidate in Alpha Centauri consistent with the one we identified in 2019 with VLT is extremely encouraging! Well done Aniket Sanghi, Chas, and team - this was a very fun project to be a part of! science.nasa.gov/missions/webb/…

Alpha Centauri A is the nearest Sun-like star. In the Avatar movie, it hosts a giant planet orbiting in its habitable zone. New JWST results suggest that it may be the case in real life too… arxiv.org/abs/2508.03812 #JWST #Exoplanets #AlphaCentauri #Avatar #Pandora

Direct images from the James Webb Space Telescope show what could be a Saturn-mass planet around Alpha Centauri. Read more: buff.ly/lMyeAIw

We may have a next door neighbor! Check out this two-paper study led by Aniket Sanghi and Chas Beichman

Astronomers have used NASA's James Webb Space Telescope to find strong evidence for a planet orbiting a star in the triple system closest to our own Sun. caltech.edu/about/news/evi…

Thanks Pierre! Wouldn’t be possible knowing where to point without you!
