Nonlinear 3D Cosmic Web Simulation with Heavy-Tailed Generative Adversarial Networks
Richard M. Feder, Philippe Berger, George Stein
Fast and accurate simulations of the non-linear evolution of the cosmic density field are a major component of many cosmological analyses, but the computational time and storage re…
Canceling out intensity mapping foregrounds
Patrick C. Breysse, Christopher J. Anderson, Philippe Berger
21 cm intensity mapping has arisen as a powerful probe of the high-redshift universe, but its potential is limited by extremely bright foregrounds and high source confusion. In thi…
Tomography of the Cosmic Dawn and Reionization Eras with Multiple Tracers
Tzu-Ching Chang, Angus Beane, Olivier Dore +41
The Cosmic Dawn and Reionization epochs remain a fundamental but challenging frontier of astrophysics and cosmology. We advocate a large-scale, multi-tracer approach to develop a c…
A volumetric deep Convolutional Neural Network for simulation of mock dark matter halo catalogues
Philippe Berger, George Stein
For modern large-scale structure survey techniques it has become standard practice to test data analysis pipelines on large suites of mock simulations, a task which is currently pr…
Testing the Origin of Cosmological Magnetic Fields through the Large-Scale Structure Consistency Relations
P. Berger, A. Kehagias, A. Riotto
We study the symmetries of the post-recombination cosmological magnetohydrodynamical equations which describe the evolution of dark matter, baryons and magnetic fields in a self-co…
