Polarization fraction of <i>Planck</i> Galactic cold clumps and forecasts for the Simons Observatory
Polarization fraction of <i>Planck</i> Galactic cold clumps and forecasts for the Simons Observatory
ABSTRACT We measure the mean-squared polarization fraction of a sample of 6282 Galactic cold clumps at 353 GHz, consisting of Planck Galactic cold clump (PGCC) catalogue category 1 objects [flux densities measured with signal-to-noise ratio (S/N) &gt; 4]. At 353 GHz, we find the mean-squared polarization fraction, which we define …
