  2. 53. Calibration strategy and mitigation of systematics effects in the QUIJOTE MFI wide survey
    Rubiño-Martín J.A.
    02/12/2020, 20:10

    I will review the current status of the QUIJOTE (Q-U-I JOint TEnerife) experiment, a project with the aim of characterising the polarisation of the Cosmic Microwave Background, and other galactic or extragalactic physical processes that emit in microwaves in the frequency range 10-42GHz, and at large angular scales (1 degree resolution). In particular, I will discuss the status of the wide...

  3. 54. A Null test framework for B-mode measurements with POLARBEAR
    Dr Yuji Chinone (The University of Tokyo)
    02/12/2020, 20:35

    The POLARBEAR experiment has achieved B-mode measurements from degree angular scales to sub-degree angular scales for searching for primordial gravitational waves and measuring gravitational lensing effects of the large-scale structure. To achieve that, we implemented a blind analysis framework so-called "null test" in our analysis. In this talk, I explain our null test framework, which could...

  4. 55. Paving the way towards a robust B-mode measurement
    Mr Joel Williams (Jodrell Bank Centre for Astrophysics - The University of Manchester)
    02/12/2020, 21:00

    The primary science goal of the vast majority of upcoming CMB experiments is the detection of B-modes sourced by primordial gravitational waves. While enhanced experimental sensitivity is essential to meet this target, diagnosing and removing sources of contamination that could potentially obscure the primordial B-mode signal will be equally important to claim a robust detection. This...

  5. 56. A minimal power-spectrum-based moment expansion for CMB B-mode searches.
    Susanna Azzoni (University of Oxford / Kavli IPMU)
    02/12/2020, 21:25

    The characterization and modelling of polarized foregrounds has become a critical issue in the quest for primordial $B$-modes. A typical method to proceed is to factorize and parametrize the spectral properties of foregrounds and their scale dependence (i.e. assuming that foreground spectra are well described everywhere by their sky-averaged spectrum). Since in reality foreground properties...
