For the past decade, the BICEP/Keck collaboration has been operating a series of telescopes at the AmundsenScott South Pole Station measuring degreescale Bmode polarization imprinted in the Cosmic Microwave Background (CMB) by primordial gravitational waves (PGWs). These telescopes are compact refracting polarimeters mapping about 2% of the sky, observing at a broad range of frequencies to account for the polarized foreground from Galactic synchrotron and thermal dust emission. Our latest publication "BK18" utilizes the data collected up to the 2018 observing season, in conjunction with the publicly available WMAP and Planck data, to constrain the tensortoscalar ratio r. It particularly includes (1) the 3year BICEP3 data which is the current deepest CMB polarization map at the foregroundminimum 95 GHz; and (2) the Keck 220 GHz map with a higher signaltonoise ratio on the dust foreground than the Planck 353 GHz map. We fit the auto and crossspectra of these maps to a multicomponent likelihood model (ΛCDM+dust+synchrotron+noise+r) and find it to be an adequate description of the data at the current noise level. The likelihood analysis yields σ(r)=0.009. The inference of r from our baseline model is tightened to r0.05=0.014+0.010−0.011 and r0.05<0.036 at 95% confidence, meaning that the BICEP/Keck Bmode datamore »

Abstract We present the
DustFilaments code, a fullsky model for the millimeter Galactic emission of thermal dust. Our model, composed of millions of filaments that are imperfectly aligned with the magnetic field, is able to reproduce the main features of the dust angular power spectra at 353 GHz as measured by the Planck mission. Our model is made up of a population of filaments with sizes following a Pareto distribution , with an axis ratio between short and long semiaxes $\propto {L}_{a}^{2.445}$ϵ ∼ 0.16 and an angle of magnetic field misalignment with a dispersion rms(θ _{LH}) = 10°. On large scales, our model follows a Planckbased template. On small scales, our model produces spectra that behave like power laws up toℓ ∼ 4000 or smaller scales by considering even smaller filaments, limited only by computing power. We can produce any number of Monte Carlo realizations of smallscale Galactic dust. Our model will allow tests of how the smallscale nonGaussianity affects CMB weak lensing and the consequences for the measurement of primordial gravitational waves or relativistic light relic species. Our model also can generate frequency decorrelation on the modified blackbody spectrum of dust and is freely adjustable to different levels of decorrelation. This can be usedmore » 
ABSTRACT In order to better analyse the polarization of the cosmic microwave background (CMB), which is dominated by emission from our Galaxy, we need tools that can detect residual foregrounds in cleaned CMB maps. Galactic foregrounds introduce statistical anisotropy and directionality to the polarization pseudovectors of the CMB, which can be investigated by using the $\mathcal {D}$ statistic of Bunn and Scott. This statistic is rapidly computable and capable of investigating a broad range of data products for directionality. We demonstrate the application of this statistic to detecting foregrounds in polarization maps by analysing the uncleaned Planck 2018 frequency maps. For the Planck 2018 CMB maps, we find no evidence for residual foreground contamination. In order to examine the sensitivity of the $\mathcal {D}$ statistic, we add a varying fraction of the polarized thermal dust and synchrotron foreground maps to the CMB maps and show the per centlevel foreground contamination that would be detected with 95 per cent confidence. We also demonstrate application of the $\mathcal {D}$ statistic to another data product by analysing the gradient of the minimumvariance CMB lensing potential map (i.e. the deflection angle) for directionality. We find no excess directionality in the lensing potential map when compared to the simulationsmore »

Abstract Modern cosmic microwave background (CMB) analysis pipelines regularly employ complex timedomain filters, beam models, masking, and other techniques during the production of sky maps and their corresponding angular power spectra. However, these processes can generate couplings between multipoles from the same spectrum and from different spectra, in addition to the typical power attenuation. Within the context of pseudo
C _{ℓ}based,MASTER style analyses, the net effect of the timedomain filtering is commonly approximated by a multiplicative transfer function,F _{ℓ}, that can fail to capture mode mixing and is dependent on the spectrum of the signal. To address these shortcomings, we have developed a simulationbased spectral correction approach that constructs a twodimensional transfer matrix, , which contains information about mode mixing in addition to mode attenuation. We demonstrate the application of this approach on data from the first flight of the ${J}_{\mathit{\ell}\mathit{\ell}\prime}$Spider balloonborne CMB experiment. 
Abstract The Cosmology Large Angular Scale Surveyor (CLASS) observes the polarized cosmic microwave background (CMB) over the angular scales of 1° ≲
θ ≤ 90° with the aim of characterizing primordial gravitational waves and cosmic reionization. We report on the onsky performance of the CLASSQ band (40 GHz),W band (90 GHz), and dichroicG band (150/220 GHz) receivers that have been operational at the CLASS site in the Atacama desert since 2016 June, 2018 May, and 2019 September, respectively. We show that the noiseequivalent power measured by the detectors matches the expected noise model based on onsky optical loading and labmeasured detector parameters. Using Moon, Venus, and Jupiter observations, we obtain power to antenna temperature calibrations and optical efficiencies for the telescopes. From the CMB survey data, we compute instantaneous array noiseequivalenttemperature sensitivities of 22, 19, 23, and 71 for the 40, 90, 150, and 220 GHz frequency bands, respectively. These noise temperatures refer to white noise amplitudes, which contribute to sky maps at all angular scales. Future papers will assess additional noise sources impacting larger angular scales. $\mu {\mathrm{K}}_{\mathrm{cmb}}\sqrt{\mathrm{s}}$
