Beyond AI as Assistants: Toward Autonomous Discovery in Cosmology

Researchers demonstrate two AI agent systems—CMBEvolve and CosmoEvolve—capable of autonomous scientific discovery in cosmology, moving beyond AI-as-tool toward AI-as-researcher. CMBEvolve uses code evolution for quantitative tasks while CosmoEvolve manages open-ended research workflows, both showing promising results in detecting anomalies and analyzing astronomical data without human intervention.

Field-level weak lensing cosmology with $<100$ simulations using multifidelity simulation-based inference

Researchers demonstrate that multifidelity simulation-based inference can extract cosmological information from weak lensing fields using fewer than 100 high-fidelity N-body simulations, achieving an order-of-magnitude reduction in computational cost. By pre-training neural models on fast, low-fidelity simulations and fine-tuning on expensive high-fidelity runs, the method enables field-level cosmological inference that captures substantially more information than traditional two-point statistics.

Cosmo3DFlow: Wavelet Flow Matching for Spatial-to-Spectral Compression in Reconstructing the Early Universe

Researchers introduced Cosmo3DFlow, a generative AI framework that combines 3D wavelet transforms with flow matching to reconstruct the early universe from present-day observations. The method achieves 46x faster sampling than diffusion models, reducing computational time from minutes to seconds for cosmological simulations at 128³ resolution.

Domain Adaptation and Reasoning Frameworks in Language Models: A Controlled Experiment with Historical Cosmology

Researchers conducted controlled experiments examining how domain adaptation reshapes language model behavior using historical cosmology as a test case. The study found that fine-tuning models on pre-Copernican text shifted their explanatory frameworks toward premodern language without directly altering underlying cosmological stance, suggesting domain adaptation primarily reorganizes linguistic patterns rather than core reasoning.
