What is the relation between volcanos, climate, galaxies, and the cosmic microwave background? Leander Thiele tells us about it in a new CAMELS blog: camel-simulations.org/blogs. Check it out!

Impressive!

My visualization for CAMELS project is featured in the #iamai video at NVIDIA #GTC22 ! (~4 minutes in the stream)

What could information about one galaxy say about the universe in which it resided? New research may hold the answer. nyer.cm/35YnRvS

Really proud of our latest paper: "Robust field-level inference with dark matter halos". We study the robustness of field-level inference to differences in N-body codes, hydrodynamics, and astrophysics using thousands of N-body and hydrodynamic simulations. We have developed a

Paper day: arxiv.org/abs/2302.14101. We train GNNs to perform field-level likelihood-free inference using galaxy catalogs from CAMELS project. Our models have no scale cutoff, achieved a precision of ~12% when inferring Ωm, and it is robust for 5 != subgrid models! Check it out!

In our new PNAS paper, we use machine learning to discover novel equations for deriving masses of clusters of galaxies from observational quantities! (1/10) pnas.org/doi/10.1073/pn… with Miles Cranmer @paco_astro@jcolinhill David Spergel Shirley Ho,Leander,Nick,Daniel,Lars.

The CAMELS project keeps growing. We have made publicly available 2,124 hydrodynamic simulations of CAMELS-ASTRID; a new suite run with the MP-Gadget code using the ASTRID subgrid physics model. All the data is accessible through globus and binder at Flatiron Institute

Here's something exciting about what the CAMELS project can do for low-redshift filament science in the near future.

Paper day: arxiv.org/abs/2310.15234. We are measuring the impact of systematics training GNNs to perform field-level simulation-based inference with galaxy catalogs from CAMELS project. We do not have and cut on scale and the models are robust. First steps before using real data!
