Validation of harmonic-space likelihood methods for LiteBIRD B-mode polarisation analysis
G. Galloni, P. Campeti, C. Gimeno-Amo +112
The LiteBIRD satellite mission aims to measure the tensor-to-scalar ratio with unprecedented sensitivity through observations of the cosmic microwave background (CMB) -mode…
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…
On the computational feasibility of Bayesian end-to-end analysis of LiteBIRD simulations within Cosmoglobe
R. Aurvik, M. Galloway, E. Gjerløw +107
We assess the computational feasibility of end-to-end Bayesian analysis of the JAXA-led LiteBIRD experiment by analysing simulated time ordered data (TOD) for a subset of detectors…
LiteBIRD Science Goals and Forecasts: constraining isotropic cosmic birefringence
E. de la Hoz, P. Diego-Palazuelos, J. Errard +112
Cosmic birefringence (CB) is the rotation of the photons' linear polarisation plane during propagation. Such an effect is a tracer of parity-violating extensions of standard electr…
Cosmoglobe DR2. I. Global Bayesian analysis of COBE-DIRBE
D. J. Watts, M. Galloway, E. Gjerløw +14
We present the first global Bayesian analysis of the time-ordered DIRBE data within the Cosmoglobe framework, building on the same methodology that has previously been successfully…
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…
Cosmoglobe DR2. II. CIB monopole measurements from COBE-DIRBE through global Bayesian analysis
D. J. Watts, M. Galloway, E. Gjerløw +13
We derive new constraints on the CIB monopole spectrum from a set of reprocessed COBE-DIRBE sky maps that have lower instrumental and astrophysical contamination than the legacy DI…
Optimal bolometer transfer function deconvolution for CMB experiments through maximum likelihood mapmaking
A. Basyrov, N. O. Stutzer, J. G. S. Lunde +4
We revisit the impact of finite time responses of bolometric detectors used for deep observations of the cosmic microwave background (CMB). Until now, bolometer transfer functions…
Cosmoglobe DR1. III. First full-sky model of polarized synchrotron emission from all WMAP and Planck LFI data
D. J. Watts, U. Fuskeland, R. Aurlien +18
We present the first model of full-sky polarized synchrotron emission that is derived from all WMAP and Planck LFI frequency maps. The basis of this analysis is the set of end-to-e…
BeyondPlanck XII. Cosmological parameter constraints with end-to-end error propagation
S. Paradiso, L. P. L. Colombo, K. J. Andersen +38
We present cosmological parameter constraints as estimated using the Bayesian BeyondPlanck (BP) analysis framework. This method supports seamless end-to-end error propagation from…
