The detection of the accelerated expansion of the Universe has been one of the major
breakthroughs in modern cosmology. Several cosmological probes (Cosmic Microwave …

Abstract The Nancy Grace Roman Space Telescope will conduct a High Latitude
Spectroscopic Survey (HLSS) over a large volume at high redshift, using the near-IR grism …

Optimal extraction of the non-Gaussian information encoded in the large-scale structure of
the Universe lies at the forefront of modern precision cosmology. We propose achieving this …

We present reconstructed convergence maps, mass maps, from the Dark Energy Survey
(DES) third year (Y3) weak gravitational lensing data set. The mass maps are weighted …

Parameter estimation with non-Gaussian stochastic fields is a common challenge in
astrophysics and cosmology. In this paper, we advocate performing this task using the …

We perform the first application of the wavelet scattering transform (WST) to actual galaxy
observations, through a WST analysis of the BOSS DR12 CMASS dataset. We included the …

We report novel cosmological constraints obtained from cosmic voids in the final BOSS
DR12 dataset. They arise from the joint analysis of geometric and dynamic distortions of …

The Euclid mission–with its spectroscopic galaxy survey covering a sky area over 15 000
deg 2 in the redshift range 0.9< z< 1.8–will provide a sample of tens of thousands of cosmic …

Do void statistics contain information beyond the tracer 2-point correlation function? Yes! As
we vary the sum of the neutrino masses, we find void statistics contain information absent …

We introduce wavelet phase harmonics (WPH) statistics: interpretable low-dimensional
statistics that describe 2D non-Gaussian fields. These statistics are built from WPH moments …
