Glad to be part of this work featuring our new exoplanet atmosphere modeling framework, SANSAR. Check it out below 👇
Our paper on the study of HD 209458 b using our newly developed in-house framework for modelling exoplanet atmospheres, SANSAR, is now published in The Astronomical Journal.🎉 🔗 iopscience.iop.org/article/10.384… #exoplanet #astronomy
New release: Astrobench, our astronomy benchmarking dataset, now available alongside Astrosage-8B: huggingface.co/datasets/Astro… @joshnguyen99's phenomenal effort has made this possible.
After a year of hard work and many failures along the way, AstroMLab is proud to present AstroSage-LLaMA-3.1-8b. Specifically designed for astronomical Q&A, this 8B parameter model achieves GPT-4o's performance level in astronomy-related question-answering tasks (with ~1/1000…
My first PhD paper is on arxiv today! Rotating planets are slightly wider at their equator compared to the poles. Saturn in our Solar System (below, minus the rings), is about 10% oblate! Can we detect this shape difference in transits from JWST? (1/N) arxiv.org/abs/2410.03449
BREAKING NEWS The Royal Swedish Academy of Sciences has decided to award the 2024 #NobelPrize in Physics to John J. Hopfield and Geoffrey E. Hinton “for foundational discoveries and inventions that enable machine learning with artificial neural networks.”
Delighted to see this new paper out, led by Ben Cassese, describing squishyplanet — a jax-based Python package to model the signals of oblate planets! arxiv.org/abs/2409.00167 Check out the readthedocs page for more, including some awesome visualizations: squishyplanet.readthedocs.io/en/latest/

For those that hope (or worry) that LLMs will do breakthrough scientific research, I've got good (or bad) news: LLMs are particularly, exceedingly, marvellously ill-suited to this task. (if you're a researcher, you'll have noticed this already) Here's why🧵
A student told me, "I don't get the difference between model fitting by: 1. minimum Mean Square Error (MSE) and 2. Maximum Likelihood Estimation (MLE)" To help this student, I built out this #Python @matplotlib dashboard for fitting a Gaussian parametric distribution to data…
Excited to announce petitRADTRANS Version 3 (pRT3). It comes with lots of quality-of-life improvements, automatic opacity downloading, more opacities, the new SpectralModel class for high-resolution spectra and data preparation, a Planet class, and so much more!
Is your brain ready for a LOT of interdisciplinary exoplanet knowledge! 🧐🤯 You know it is! 🧵In Jan 2021, Keith Putirka, Siyi Xu, and I joined forces to put together 15 chapters (and a workshop!**) written by experts in their field, where the core of each chapter was:
