Snowmass2021 CMB-HD White Paper
HD Collaboration, Simone Aiola, Yashar Akrami +61
CMB-HD is a proposed millimeter-wave survey over half the sky that would be ultra-deep (0.5 uK-arcmin) and have unprecedented resolution (15 arcseconds at 150 GHz). Such a survey w…
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…
Mitigating baryonic effects with a theoretical error covariance
Maria G. Moreira, Felipe Andrade-Oliveira, Xiao Fang +5
One of the primary sources of uncertainties in modeling the cosmic-shear power spectrum on small scales is the effect of baryonic physics. Accurate cosmology for Stage-IV surveys r…

Interpreting Internal Consistency of DES Measurements
V. Miranda, P. Rogozenski, E. Krause
Bayesian evidence ratios are widely used to quantify the statistical consistency between different experiments. However, since the evidence ratio is prior dependent, the precise tr…
