FOSSIL: A future mission for CMB spectral distortion measurements
N. Aghanim, B. Maffei, J. Aumont +96
We present FOSSIL, a proposed space mission which is designed to deliver unprecedented absolute spectroscopic measurements of the sky intensity over a broad frequency range (50GHz…
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
We present a cross-calibration algorithm that determines the relative calibration of detectors within the same frequency band of a CMB experiment. The method iteratively compares s…
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…
Combining CMB datasets with consistent foreground modelling
M. Tristram, M. Douspis, A. Gorce +7
We present a joint cosmological analysis combining data from the Planck satellite, the Atacama Cosmology Telescope, and the South Pole Telescope. We construct a unified likelihood…
LiteBIRD Science Goals and Forecasts. -mode Anomalies
A. J. Banday, C. Gimeno-Amo, P. Diego-Palazuelos +101
Various so-called anomalies have been found in both the WMAP and Planck cosmic microwave background (CMB) temperature data that exert a mild tension against the highly successful b…
LiteBIRD science goals and forecasts: improved full-sky reconstruction of the gravitational lensing potential through the combination of Planck and LiteBIRD data
M. Ruiz-Granda, P. Diego-Palazuelos, C. Gimeno-Amo +102
Cosmic microwave background (CMB) photons are deflected by large-scale structure through gravitational lensing. This secondary effect introduces higher-order correlations in CMB an…
Requirements on bandpass resolution and measurement precision for LiteBIRD
S. Giardiello, A. Carones, T. Ghigna +95
In this work, we study the impact of an imperfect knowledge of the instrument bandpasses on the estimate of the tensor-to-scalar ratio in the context of the next-generation Lit…
Reconstructing the epoch of reionisation with Planck PR4
S. Ilić, M. Tristram, M. Douspis +8
The epoch of reionisation is a key phase in cosmic history, characterised by the ionisation of the intergalactic medium by the first luminous sources. In this work, we constrain th…
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…
Requirements on the gain calibration for LiteBIRD polarisation data with blind component separation
F. Carralot, A. Carones, N. Krachmalnicoff +106
Future cosmic microwave background (CMB) experiments are primarily targeting a detection of the primordial -mode polarisation. The faintness of this signal requires exquisite co…
LiteBIRD Science Goals and Forecasts. Mapping the Hot Gas in the Universe
M. Remazeilles, M. Douspis, J. A. Rubiño-Martín +104
We assess the capabilities of the LiteBIRD mission to map the hot gas distribution in the Universe through the thermal Sunyaev-Zeldovich (SZ) effect. Our analysis relies on compreh…
Planck intermediate results. XLVIII. Disentangling Galactic dust emission and cosmic infrared background anisotropies
Planck Collaboration, N. Aghanim, M. Ashdown +157
Using the Planck 2015 data release (PR2) temperature maps, we separate Galactic thermal dust emission from cosmic infrared background (CIB) anisotropies. For this purpose, we imple…
Planck 2013 results. XXXI. Consistency of the Planck data
Planck Collaboration, P. A. R. Ade, M. Arnaud +180
The Planck design and scanning strategy provide many levels of redundancy that can be exploited to provide tests of internal consistency. One of the most important is the compariso…
Planck 2015 results. VI. LFI mapmaking
Planck Collaboration, P. A. R. Ade, N. Aghanim +198
This paper describes the mapmaking procedure applied to Planck LFI (Low Frequency Instrument) data. The mapmaking step takes as input the calibrated timelines and pointing informat…
Planck 2015 results. XXI. The integrated Sachs-Wolfe effect
Planck Collaboration, P. A. R. Ade, N. Aghanim +229
This paper presents a study of the ISW effect from the Planck 2015 temperature and polarization data release. The CMB is cross-correlated with different LSS tracers: the NVSS, SDSS…
Planck intermediate results. XXX. The angular power spectrum of polarized dust emission at intermediate and high Galactic latitudes
Planck Collaboration, R. Adam, P. A. R. Ade +230
The polarized thermal emission from Galactic dust is the main foreground present in measurements of the polarization of the cosmic microwave background (CMB) at frequencies above 1…
A novel estimator of the polarization amplitude from normally distributed Stokes parameters
S. Plaszczynski, L. Montier, F. Levrier +1
We propose a novel estimator of the polarization amplitude from a single measurement of its normally distributed Stokes components. Based on the properties of the Rice dist…
