Probing Cosmology with Diffusion Models: Memorization, Generalization, and Parameter Estimation
Jiaming Pan, Nicholas Kern
Diffusion models are increasingly used as surrogates for expensive cosmological simulations, but simple metrics like reconstruction fidelity do not guarantee a surrogate can be tru…
Determining the Hubble Constant through Cross-Correlation of Galaxies and Gravitational Waves
Jiaming Pan, Dragan Huterer, Camille Avestruz +4
Gravitational wave (GW) standard sirens have the potential to measure the Hubble constant in the local universe independently of the distance ladder, and thus offer unique ne…
Compressed baryon acoustic oscillation analysis is robust to modified-gravity models
Jiaming Pan, Dragan Huterer, Felipe Andrade-Oliveira +1
We study the robustness of the baryon acoustic oscillation (BAO) analysis to the underlying cosmological model. We focus on testing the standard BAO analysis that relies on the use…
