Field-Level Inference of Primordial Non-Gaussianity with the Quijote Simulation Suite
Adam Andrews, Jens Jasche, Guilhem Lavaux +10
Local primordial non-Gaussianity, parameterised as , will be stringently constrained using state-of-the-art methods applied to next-generation galaxy redshi…
The constraining power of the Marked Power Spectrum: an analytical study
Marco Marinucci, Gabriel Jung, Michele Liguori +8
The marked power spectrum - a two-point correlation function of a transformed density field - has emerged as a promising tool for extracting cosmological information from the large…
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…
Constraining Primordial Non-Gaussianity from Large Scale Structure with the Wavelet Scattering Transform
Matteo Peron, Gabriel Jung, Michele Liguori +1
We investigate the Wavelet Scattering Transform (WST) as a tool for the study of Primordial non-Gaussianity (PNG) in Large Scale Structure (LSS), and compare its performance with t…
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…
Taming assembly bias for primordial non-Gaussianity
Emanuele Fondi, Licia Verde, Francisco Villaescusa-Navarro +7
Primordial non-Gaussianity of the local type induces a strong scale-dependent bias on the clustering of halos in the late-time Universe. This signature is particularly promising to…
Quijote-PNG: The Information Content of the Halo Mass Function
Gabriel Jung, Andrea Ravenni, Marco Baldi +8
We study signatures of primordial non-Gaussianity (PNG) in the redshift-space halo field on non-linear scales, using a combination of three summary statistics, namely the halo mass…
Quijote-PNG: Quasi-maximum likelihood estimation of Primordial Non-Gaussianity in the non-linear halo density field
Gabriel Jung, Dionysios Karagiannis, Michele Liguori +6
We study primordial non-Gaussian signatures in the redshift-space halo field on non-linear scales, using a quasi-maximum likelihood estimator based on optimally compressed power sp…
Quijote-PNG: Quasi-maximum likelihood estimation of Primordial Non-Gaussianity in the non-linear dark matter density field
Gabriel Jung, Dionysios Karagiannis, Michele Liguori +6
Future Large Scale Structure surveys are expected to improve over current bounds on primordial non-Gaussianity (PNG), with a significant impact on our understanding of early Univer…
Quijote PNG: The information content of the halo power spectrum and bispectrum
William R Coulton, Francisco Villaescusa-Navarro, Drew Jamieson +6
We investigate how much can be learnt about four types of primordial non-Gaussianity (PNG) from small-scale measurements of the halo field. Using the QUIJOTE-PNG simulations, we qu…
Quijote-PNG: Simulations of primordial non-Gaussianity and the information content of the matter field power spectrum and bispectrum
William R Coulton, Francisco Villaescusa-Navarro, Drew Jamieson +6
Primordial non-Gaussianity (PNG) is one of the most powerful probes of the early Universe and measurements of the large scale structure of the Universe have the potential to transf…
Position-Dependent Correlation Function of Weak Lensing Convergence
D. Munshi, G. Jung, T. D. Kitching +4
We provide a systematic study of the position-dependent correlation function in weak lensing convergence maps and its relation to the squeezed limit of the three-point correlation…
The integrated angular bispectrum of weak lensing
Gabriel Jung, Toshiya Namikawa, Michele Liguori +2
We investigate three-point statistics in weak lensing convergence, through the integrated bispectrum. This statistic involves measuring power spectra in patches, and is thus easy t…
The integrated angular bispectrum
Gabriel Jung, Filippo Oppizzi, Andrea Ravenni +1
We study the position-dependent power spectrum and the integrated bispectrum statistic for 2D cosmological fields on the sphere (integrated angular bispectrum). First, we derive a…
Planck 2018 results. IX. Constraints on primordial non-Gaussianity
Planck Collaboration, Y. Akrami, F. Arroja +157
We analyse the Planck full-mission cosmic microwave background (CMB) temperature and E-mode polarization maps to obtain constraints on primordial non-Gaussianity (NG). We compare e…
Non-Gaussianity in two-field inflation beyond the slow-roll approximation
Gabriel Jung, Bartjan van Tent
We use the long-wavelength formalism to investigate the level of bispectral non-Gaussianity produced in two-field inflation models with standard kinetic terms. Even though the Plan…
Dark Matter in Light of LUX
Patrick J. Fox, Gabriel Jung, Peter Sorensen +1
The landscape of dark matter direct detection has been profoundly altered by the slew of recent experiments. While some have claimed signals consistent with dark matter, others hav…
