Primordial non-Gaussianity without tails -- how to measure fNL with the bulk of the density PDF

Oliver Friedrich, Cora Uhlemann, Francisco Villaescusa-Navarro +3

We investigate the possibility to detect primordial non-Gaussianity by analysing the bulk of the probability distribution function (PDF) of late-time cosmic density fluctuations. F…

GEOMAX: beyond linear compression for 3pt galaxy clustering statistics

Davide Gualdi, Héctor Gil-Marín, Marc Manera +2

We present the GEOMAX algorithm and its Python implementation for a two-step compression of bispectrum measurements. The first step groups bispectra by the geometric properties of…

Dark Energy Survey Year 3 results: cosmology with moments of weak lensing mass maps -- validation on simulations

M. Gatti, C. Chang, O. Friedrich +69

We present a simulated cosmology analysis using the second and third moments of the weak lensing mass (convergence) maps. The analysis is geared towards the third year (Y3) data fr…

Blinding multi-probe cosmological experiments

J. Muir, G. M. Bernstein, D. Huterer +62

The goal of blinding is to hide an experiment's critical results -- here the inferred cosmological parameters -- until all decisions affecting its analysis have been finalised. Thi…

Dark Energy Survey Year 1 Results: the lensing imprint of cosmic voids on the Cosmic Microwave Background

P. Vielzeuf, A. Kovács, U. Demirbozan +62

Cosmic voids gravitationally lens the cosmic microwave background (CMB) radiation, resulting in a distinct imprint on degree scales. We use the simulated CMB lensing convergence ma…

Detection of cross-correlation between gravitational lensing and gamma rays

S. Ammazzalorso, D. Gruen, M. Regis +75

In recent years, many gamma-ray sources have been identified, yet the unresolved component hosts valuable information on the faintest emission. In order to extract it, a cross-corr…
