I am now a comic book character 😻 This is a result of amazing collaboration between @sciallorg and @IfThenSheCan, to inspire middle schoolers into STEM fields. Amazing art work by @JuaneleTamal!

Paper thread!! This was up on arXiv a bit over a week ago: arxiv.org/abs/2405.13124
We show here the dynamical analysis of the first spectroscopic follow-up of extremely metal-poor stars using photometric metallicities based on Gaia XP CaHK magnitudes run on Pristine survey model

Happy to announce the workshop Dwarf Galaxies, Star Clusters, and Streams in the LSST Era, taking place at @UChicago from July 8-11, 2024. kicp-workshops.uchicago.edu/2024-DGSCS/ind….

Check out our paper on NGC253's satellite system, and satellite systems around MW-mass hosts in general: arxiv.org/pdf/2401.14457…. We find no convincing evidence for the presence of a plane of satellites surrounding NGC253.

We pitted Φ-SO against 17 leading symbolic regression algorithms in the quest to rediscover >100 equations from the Feynman Lectures on physics! 📝🔬🌌
🌟 I am thrilled to announce that Φ-SO is the new state of the art in the presence of noise ! 🌟

The 23rd paper of the main series of papers from the Pristine survey is out! It's been a lot of work by a lot of people since @ESAGaia's Data Release 3 came out.
It's also the first Data Release from the survey and we publish catalogues for ~30+ million stellar metallicities. 🥳

Today my first first-author paper hit the arXiv 😄: An action-based dynamical model for M31-like stellar halos.

@joannasakowska For now, no sign of covid on our side. Take care!

Well #IAUS379 was productive in many ways… including taking away my no-covid bragging rights

So happy to have won this prize and that people were excited about our results on M31 dwarf galaxies! ✨
There are still lots of satellites to discover! 🔭 #iaus379

Having SO much fun at #iaus379 ! Check out my poster on the star formation history of the Small Magellanic Cloud’s “Shell” 🐚 and what it reveals about the LMC/SMC’s co-evolution 😊✨

Hello, this week I'm at the #iaus379 😁 If you'd like check out my poster on how I model M31-like halos using an action-based dynamical approach in order to constrain their DM profiles, masses, and stellar halo phase space distributions. If you'd like to chat, let me know!

I'm really amazed at the results obtained by @astro_wassim and Φ-SO! 🤖✨

After 1.5 years of hard work, I am thrilled to share with you Φ-SO - a Physical Symbolic Optimization package that uses deep reinforcement learning to discover physical laws from data . Here is Φ-SO discovering the analytical expression of a damped harmonic oscillator👇 [1/6]

This work included many people such with some that are here: @nfmartin1980, @Thomas_gft, @Cosmic_Horizons, @stacyyckim.

Finally, with the arrival of LSST and Euclid, this statistical framework opens the possibility to perform an homogeneous analysis of a significant number of satellite systems!
