Cosmological simulations of scale-dependent primordial non-Gaussianity
Marco Baldi, Emanuele Fondi, Dionysios Karagiannis +9
We present the results of a set of cosmological N-body simulations with standard CDM cosmology but characterized by a scale-dependent primordial non-Gaussianity of the local typ…
The Impact of Non-Gaussian Primordial Tails on Cosmological Observables
William R. Coulton, Oliver H. E. Philcox, Francisco Villaescusa-Navarro
Whilst current observational evidence favors a close-to-Gaussian spectrum of primordial perturbations, there exist many models of the early Universe that predict this distribution…
GANSky -- fast curved sky weak lensing simulations using Generative Adversarial Networks
Supranta S. Boruah, Pier Fiedorowicz, Rafael Garcia +3
Extracting non-Gaussian information from the next generation weak lensing surveys will require fast and accurate full-sky simulations. This is difficult to achieve in practice with…
Denoising Diffusion Delensing Delight: Reconstructing the Non-Gaussian CMB Lensing Potential with Diffusion Models
Thomas Flöss, William R. Coulton, Adriaan J. Duivenvoorden +2
Optimal extraction of cosmological information from observations of the Cosmic Microwave Background critically relies on our ability to accurately undo the distortions caused by we…
Quijote-PNG: Optimizing the summary statistics to measure Primordial non-Gaussianity
Gabriel Jung, Andrea Ravenni, Michele Liguori +4
We apply a suite of different estimators to the Quijote-PNG halo catalogues to find the best approach to constrain Primordial non-Gaussianity (PNG) at non-linear cosmological scale…
Small-scale signatures of primordial non-Gaussianity in k-Nearest Neighbour cumulative distribution functions
William R. Coulton, Tom Abel, Arka Banerjee
Searches for primordial non-Gaussianity in cosmological perturbations are a key means of revealing novel primordial physics. However, robustly extracting signatures of primordial n…
