HIGlow: Conditional Normalizing Flows for High-Fidelity HI Map Modeling
Roy Friedman, Sultan Hassan
Extracting the maximum amount of cosmological and astrophysical information from upcoming large-scale surveys remains a challenge. This includes evaluating the exact likelihood, pa…
Emulating cosmological multifields with generative adversarial networks
Sambatra Andrianomena, Francisco Villaescusa-Navarro, Sultan Hassan
We explore the possibility of using deep learning to generate multifield images from state-of-the-art hydrodynamic simulations of the CAMELS project. We use a generative adversaria…
Towards a non-Gaussian Generative Model of large-scale Reionization Maps
Yu-Heng Lin, Sultan Hassan, Bruno Régaldo-Saint Blancard +2
High-dimensional data sets are expected from the next generation of large-scale surveys. These data sets will carry a wealth of information about the early stages of galaxy formati…
Bridging the Gap between Cosmic Dawn and Reionization favors Faint Galaxies-dominated Models
Ankita Bera, Sultan Hassan, Aaron Smith +4
It has been claimed that traditional models struggle to explain the tentative detection of the 21\,cm absorption trough centered at measured by the EDGES collaboration. O…
Predictive uncertainty on improved astrophysics recovery from multifield cosmology
Sambatra Andrianomena, Sultan Hassan
We investigate how the constraints on cosmological and astrophysical parameters (, , , ) vary when exploiting information from multiple…
Wavelet Moments for Cosmological Parameter Estimation
Michael Eickenberg, Erwan Allys, Azadeh Moradinezhad Dizgah +10
Extracting non-Gaussian information from the non-linear regime of structure formation is key to fully exploiting the rich data from upcoming cosmological surveys probing the large-…
The CAMELS project: public data release
Francisco Villaescusa-Navarro, Shy Genel, Daniel Anglés-Alcázar +44
The Cosmology and Astrophysics with MachinE Learning Simulations (CAMELS) project was developed to combine cosmology with astrophysics through thousands of cosmological hydrodynami…
