Forecasting ground-based sensitivity to the Rayleigh scattering of the CMB in the presence of astrophysical foregrounds

Kavli Affiliate: W. L. Kimmy Wu | First 5 Authors: Karia R. Dibert, Adam J. Anderson, Amy N. Bender, Bradford A. Benson, Federico Bianchini | Summary: The Rayleigh scattering of cosmic microwave background (CMB) photons off the neutral hydrogen produced during recombination effectively creates an additional scattering surface after recombination that encodes new cosmological information, […]

Insights into the origin of halo mass profiles from machine learning

Kavli Affiliate: Risa H. Wechsler | First 5 Authors: Luisa Lucie-Smith, Susmita Adhikari, Risa H. Wechsler, , | Summary: The mass distribution of dark matter haloes is the result of the hierarchical growth of initial density perturbations through mass accretion and mergers. We use an interpretable machine-learning framework to provide physical insights into the origin […]
