DES Y3 results: Blending shear and redshift biases in image simulations

N. MacCrann, M. R. Becker, J. McCullough +93

As the statistical power of galaxy weak lensing reaches percent level precision, large, realistic and robust simulations are required to calibrate observational systematics, especi…

Consistency of cosmic shear analyses in harmonic and real space

C. Doux, C. Chang, B. Jain +67

Recent cosmic shear studies have reported discrepancies of up to on the parameter between the analysis of shear power spectra and two-point…

Dark Energy Survey internal consistency tests of the joint cosmological probes analysis with posterior predictive distributions

C. Doux, E. Baxter, P. Lemos +85

Beyond-CDM physics or systematic errors may cause subsets of a cosmological data set to appear inconsistent when analyzed assuming CDM. We present an application of internal…
