Implementation of frequency-correlated noise in CMB component separation: Method, Validation, and Early Applications
L. Zapelli, M. Bersanelli, L. P. L. Colombo +24
Parametric component separation methods used in cosmic microwave background (CMB) analyses commonly assume instrumental noise to be uncorrelated between frequency channels. This ap…
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…
N+2 Mapmaking for Polarized CMB Experiments
M. Galloway, H. K. Eriksen, R. M. Sullivan +3
We introduce N+2 mapmaking as a novel approach to constructing maps in both intensity and polarization for multi-detector CMB data. The motivation behind this method is two-fold: F…
Cosmoglobe DR2. III. Improved modelling of zodiacal light with COBE-DIRBE through global Bayesian analysis
M. San, A. Bonato, M. Galloway +20
We present an improved zodiacal light (ZL) model for COBE-DIRBE derived through global Bayesian analysis within the Cosmoglobe Data Release 2 framework. The parametric form of the…
The advantage of Bolometric Interferometry for controlling Galactic foreground contamination in CMB primordial B-modes measurements
E. Manzan, M. Regnier, J-Ch. Hamilton +18
In the quest for the faint primordial B-mode polarization of the Cosmic Microwave Background, three are the key requirements for any present or future experiment: an utmost sensiti…
Identifying frequency decorrelated dust residuals in B-mode maps by exploiting the spectral capability of bolometric interferometry
M. Regnier, E. Manzan, J. -Ch Hamilton +21
Astrophysical polarized foregrounds represent the most critical challenge in Cosmic Microwave Background (CMB) B-mode experiments. Multi-frequency observations can be used to const…
