A method called the degeneracy distillery uses symbolic transformations to flatten the Fisher information matrix globally from simulations alone, identifying independent parameter combinations and reducing neural posterior estimation simulation budgets by up to 10x.
GraphGP delivers a linear-scaling GPU implementation of Vecchia's sparse precision approximation for Gaussian processes on arbitrary point sets using a bit-reversed k-d tree and CUDA kernels.
The Via Project is a planned five-year dual-hemisphere spectroscopic survey targeting over 2 million stars with 100 m/s RV stability and transient spectroscopy to r~24 using instruments on MMT and Magellan/Clay telescopes starting in 2027.
Bayesian analysis of SKA Faraday rotation data can constrain magnetization in galaxy clusters using about 50,000 measurements with precise redshifts, while filaments remain challenging even with 17,000 spectroscopic redshifts.
