  • BICEP / Keck XIII: Improved Constraints on Primordial Gravitational Waves using Planck, WMAP, and BICEP/Keck Observations through the 2018 Observing Season, arXiv:2110.00483

    The "BK18" analysis utilizes BICEP/Keck CMB B-mode data to derive constraints on the tensor-to-scalar ratio r and inflation models. It gives r < 0.036 and σ(r) = 0.009 which is the smallest to date. I have made major contributions to this paper.

  • The Latest Constraints on Inflationary B-modes from the BICEP/Keck Telescopes, arXiv:2203.16556

    I wrote this conference proceeding for a 25 minute plenary BK18 talk given in the Cosmology session of the 56th Rencontres de Moriond. The BK27+SPT-3G forecast is also included.

  • Relic Neutrino Degeneracies and Their Impact on Cosmological Parameters, arXiv:2010.01696

    I wrote this paper to study the impacts of neutrino degeneracies in CMB data fitting, particularly for the constraint of the Hubble parameter and the spectral index.
