  2. 59. Simultaneous determination of the cosmic birefringence and miscalibrated polarization angles
    Dr Yuto Minami (KEK)

    We show that the cosmic birefringence and miscalibrated polarization angles can be determined simultaneously by cosmic microwave background (CMB) experiments using the cross-correlation between $E$- and $B$-mode polarization data. This is possible because the polarization angles of the CMB are rotated by both the cosmic birefringence and miscalibration effects, whereas those of the Galactic...

  3. 60. Analysis of Temperature-to-Polarization Leakage in BICEP3 and Keck Array CMB Data from 2016 to 2018
    Tyler St Germaine (Harvard University)

    The BICEP/Keck (BK) experiment is a series of small-aperture refracting telescopes observing degree-scale Cosmic Microwave Background (CMB) polarization from the South Pole in search of a primordial B-mode signature. This B-mode signal arises from inflationary gravitational waves interacting with the CMB, and has amplitude parametrized by the tensor-to-scalar ratio r. As a pair differencing...

  4. 61. Systematics in delensing
    Dr Kimmy Wu
    03/12/2020, 09:10

    In this talk, I will first present the systematics considered and their impact on the constraint on the tensor-to-scalar ratio r in delensing the BICEP/Keck data. Then, I will discuss systematics considerations for future delensing analyses.

  5. 62. Optimizing the interplay of systematic effects and observing strategy in CMB space missions
    Dr Giuseppe Puglisi (UC Berkeley)
    03/12/2020, 09:35

    CMB space missions are uniquely capable of probing the very largest angular scales for the primordial B-mode reionization bump which is the signal least susceptible to contamination from lensing.

    A critical piece of this framework will necessarily be the ability of generating synthetic mission datasets of sufficient realism, both in their complexity and their size, to be truly...
