Happy to say that my second paper “Astrometric exoplanet detection survives solar-like stellar contamination” has been accepted by MNRAS and is now up on the arxiv: arxiv.org/pdf/2605.18953 Takeaway: Missions like TOLIMAN and SHERA could find earth-twins assuming solar like noise.

Let me recommend grabbing a cup of tea & reading this really thoughtful piece from the inimitable @hogg.bsky.social on moderating AI/LLM use in astrophysics. 🔭 "the real question we face is not ... how we do astrophysics. It is the question of why we do astrophysics." 📖: arxiv.org/pdf/2602.10181
A screenshot of text from a paper that reads:

One idea or rule of thumb is perhaps that we should or could interact with an LLM only in the same ways that we would interact with a non-coauthor colleague. You might ask your colleague for help finding something in the literature, but you wouldn’t ask your non-coauthor colleague to write the introduction of the paper you are writing. You might ask your colleague to help speed up your code, but you wouldn’t
ask your colleague to write your code. Another idea is that, given our respect for our readers, we shouldn’t ask them to engage with something that took way less time to write than to read. I like these ideas; maybe they could evolve into conventions or community-supported best practices.

Our NASA’s Pandora space telescope is on orbit!! Congrats to the team and NASA, LSP, SpaceX, and everyone who helped to get to this exciting point! What will Pandora do and why is it important for exoplanet science? Read my short article on this: theconversation.com/nasas-pandor...

NASA’s Pandora telescope will study stars in detail to learn about the exoplanets orbiting them
The findings from Pandora will complement data from the James Webb Space Telescope to give astronomers more insight into stars and planets outside our solar system.

1/ 🌀 New paper alert! We introduce Dingo-T1, a flexible transformer-based deep learning model for gravitational-wave (GW) data analysis. It adapts to different detector & frequency settings, improving inference efficiency and flexibility 🚀 #AI #MachineLearning #Physics #Astronomy #AcademicSky
Scientific poster with dark background and two black holes illustrated in the center. The paper visualizes gravitational waves, and explains how parameter estimation is performed with DINGO. The standard DINGO model and the DINGO-T1 architectures are illustrated and results are shown. For example, it is possible to reanalyze the same event with different detector configurations with DINGO-T1, illustrated bz a corner plot.

In the struggle and humility of Lenten prayer, back then and now—they blessed the stars or cursed them there. From caves they gazed in wonder, from towers reached in vain, tried to grasp the menace and the mystery they contain.
