MG-NECOLA: A Field-Level Emulator for Gravity and Massive Neutrino Cosmologies
J. Bayron Orjuela-Quintana, Mauricio Reyes, Elena Giusarma +3
Accurate modeling of non-linear gravitational dynamics is essential for constraining extensions to the standard cosmological model using large-scale structure observations. While h…
MG-NECOLA: Fast Neural Emulators for Modified Gravity Cosmologies
J. Bayron Orjuela-Quintana, Mauricio Reyes, Elena Giusarma +3
Observations of the large-scale structure (LSS) provide a powerful test of gravity on cosmological scales, but high-resolution N-body simulations of modified gravity (MG) are prohi…
The CosmoVerse White Paper: Addressing observational tensions in cosmology with systematics and fundamental physics
Eleonora Di Valentino, Jackson Levi Said, Adam Riess +533
The standard model of cosmology has provided a good phenomenological description of a wide range of observations both at astrophysical and cosmological scales for several decades.…
nuGAN: Generative Adversarial Emulator for Cosmic Web with Neutrinos
Neerav Kaushal, Elena Giusarma, Mauricio Reyes
Understanding the impact of neutrino masses on the evolution of Universe is a crucial aspect of modern cosmology. Due to their large free streaming lengths, neutrinos significantly…
Probabilistic Galaxy Field Generation with Diffusion Models
Tanner Sether, Elena Giusarma, Mauricio Reyes-Hurtado
In the era of precision cosmology, the ability to generate accurate and large-scale galaxy catalogs is crucial for advancing our understanding of the universe. With the flood of co…
