Cosmic Shear in Harmonic Space from the Dark Energy Survey Year 1 Data: Compatibility with Configuration Space Results
H. Camacho, F. Andrade-Oliveira, A. Troja +96
We perform a cosmic shear analysis in harmonic space using the first year of data collected by the Dark Energy Survey (DES-Y1). We measure the cosmic weak lensing shear power spect…
Dark Energy Survey Year 3 results: Marginalisation over redshift distribution uncertainties using ranking of discrete realisations
Juan P. Cordero, Ian Harrison, Richard P. Rollins +92
Cosmological information from weak lensing surveys is maximised by dividing source galaxies into tomographic sub-samples for which the redshift distributions are estimated. Uncerta…
Matching Bayesian and frequentist coverage probabilities when using an approximate data covariance matrix
Will J. Percival, Oliver Friedrich, Elena Sellentin +1
Observational astrophysics consists of making inferences about the Universe by comparing data and models. The credible intervals placed on model parameters are often as important a…
The PDF perspective on the tracer-matter connection: Lagrangian bias and non-Poissonian shot noise
Oliver Friedrich, Anik Halder, Aoife Boyle +5
We study the connection of matter density and its tracers from the PDF perspective. One aspect of this connection is the conditional expectation value $\langle δ_{\mathrm{tracer}}|…
A revised density split statistic model for general filters
Pierre Burger, Oliver Friedrich, Joachim Harnois-Déraps +1
Studying the statistical properties of the large-scale structure in the Universe with weak gravitational lensing is a prime goal of several current and forthcoming galaxy surveys.…
Dark Energy Survey Year 3 results: cosmology from combined galaxy clustering and lensing -- validation on cosmological simulations
J. DeRose, R. H. Wechsler, M. R. Becker +114
We present a validation of the Dark Energy Survey Year 3 (DES Y3) -point analysis choices by testing them on Buzzard v2.0, a new suite of cosmological simulations that is…
