A cross-calibration approach for polarisation-sensitive detectors in CMB experiments: application to LiteBIRD's polarisation angle calibration
A. Novelli, F. Piacentini, S. Micheli +102
One of the current challenges in observational cosmology is obtaining high-precision polarisation maps of the CMB to measure primordial -modes and constrain the tensor-to-scalar…
Mitigating half-wave plate systematics at the map-making level: calibration requirements for LiteBIRD
N. Raffuzzi, A. Carones, M. Monelli +101
Although half-wave plates (HWPs) are becoming a popular choice of polarization modulators for cosmic microwave background (CMB) experiments, their non-idealities can introduce syst…
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 DR2. IV. Modelling starlight in DIRBE with Gaia and WISE
M. Galloway, E. Gjerløw, M. San +20
We present a model of starlight emission in the Diffuse Infrared Background Explorer (DIRBE) data between 1.25 and 25m based on \textit{Gaia} and WISE measurements. We include…
Cosmoglobe DR2. VII. Towards a concordance model of large-scale thermal dust emission for microwave and infrared frequencies
E. Gjerløw, R. M. Sullivan, R. Aurvik +20
We fit a four-component thermal dust model to COBE-DIRBE data between 3.5 and 240 micron within the global Bayesian end-to-end Cosmoglobe DR2 reanalysis. Following a companion anal…
Cosmoglobe DR2. V. Spatial correlations between thermal dust and ionized carbon emission in Planck HFI and COBE-DIRBE
E. Gjerløw, R. M. Sullivan, R. Aurvik +20
We fit five tracers of thermal dust emission to ten Planck HFI and COBE-DIRBE frequency maps between 353 GHz and 25 THz, aiming to map the relative importance of each physical host…
