Cosmoglobe DR2. VI. Disentangling hot and cold thermal dust emission with Planck HFI

R. M. Sullivan, E. Gjerløw, M. Galloway +20

We present a four-component high-resolution model of thermal dust emission for microwave and sub-mm frequencies derived from Planck HFI, WHAM and Gaia. The resulting high-resolutio…

Cosmoglobe DR1 results. II. Constraints on isotropic cosmic birefringence from reprocessed WMAP and Planck LFI data

J. R. Eskilt, D. J. Watts, R. Aurlien +28

Cosmic birefringence is a parity-violating effect that might have rotated the plane of linearly polarized light of the cosmic microwave background (CMB) by an angle since its e…
