Hierarchical Bayesian CMB Component Separation with the No-U-Turn Sampler
R. D. P. Grumitt, Luke R. P. Jew, C. Dickinson
In this paper we present a novel implementation of Bayesian CMB component separation. We sample from the full posterior distribution using the No-U-Turn Sampler (NUTS), a gradient-…
The C-Band All-Sky Survey (C-BASS): Total intensity point-source detection over the northern sky
R. D. P. Grumitt, Angela C. Taylor, Luke Jew +14
We present a point-source detection algorithm that employs the second order Spherical Mexican Hat wavelet filter (SMHW2), and use it on C-BASS northern intensity data to produce a…
The C-Band All-Sky Survey (C-BASS): Simulated parametric fitting in single pixels in total intensity and polarization
Luke Jew, Angela C. Taylor, Michael E. Jones +14
The cosmic microwave background -mode signal is potentially weaker than the diffuse Galactic foregrounds over most of the sky at any frequency. A common method of separating the…
The spectral index of polarized diffuse Galactic emission between 30 and 44 GHz
Luke Jew, Richard Grumitt
We present an estimate of the polarized spectral index between the Planck 30 and 44 GHz surveys in pixels across the entire sky. We use an objective reference prior tha…
