The impact of spectroscopic incompleteness in direct calibration of redshift distributions for weak lensing surveys
W. G. Hartley, C. Chang, S. Samani +74
Obtaining accurate distributions of galaxy redshifts is a critical aspect of weak lensing cosmology experiments. One of the methods used to estimate and validate redshift distribut…
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…
Quantifying Suspiciousness Within Correlated Data Sets
Pablo Lemos, Fabian Köhlinger, Will Handley +3
We propose a principled Bayesian method for quantifying tension between correlated datasets with wide uninformative parameter priors. This is achieved by extending the Suspiciousne…
Beyond two-point statistics: using the minimum spanning tree as a tool for cosmology
Krishna Naidoo, Lorne Whiteway, Elena Massara +5
Cosmological studies of large-scale structure have relied on two-point statistics, not fully exploiting the rich structure of the cosmic web. In this paper we show how to capture s…
Upper Bound of Neutrino Masses from Combined Cosmological Observations and Particle Physics Experiments
Arthur Loureiro, Andrei Cuceu, Filipe B. Abdalla +9
We investigate the impact of prior models on the upper bound of the sum of neutrino masses, . We use data from Large Scale Structure of galaxies, Cosmic Microwave Backgro…
