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…
Proof of concept of the COSMOCal project at the IRAM 30m telescope
S. Savorgnano, L. Bizzarri, A. Ritacco +25
This work reports on a test campaign conducted at the IRAM 30m telescope to validate the COSMOCal instrument, a novel concept for absolute calibration of polarization angle, beam p…
LiteBIRD Mission Overview after Mission Reformation
LiteBIRD Collaboration, K. Aizawa, H. Akamatsu +172
LiteBIRD is a JAXA-led space mission designed to produce all-sky microwave polarization maps. Its primary science goal is to test representative inflationary models by measuring th…
Status and future development of the COSMOCal Project for absolute CMB polarization calibration
Silvia Micheli, Alessia Ritacco, Alessandro Carones +36
Cosmic Microwave Background (CMB) polarization measurements are pushing instrumental sensitivities to levels where calibration systematics become a dominant limitation. The large d…
Cosmology from Nx2pt Analyses of SKAO Wide-Area Surveys
Ian Harrison, Ziad Sakr, Giulia Piccirilli +7
SKAO surveys will provide an unprecedented window into the large-scale structure of the universe through HI 21cm galaxy and intensity mapping surveys, and radio continuum surveys.…
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…
Status of the COSmological Microwave Observations CALibrator
L. Mousset, J. Aumont, S. Berta +33
As the sensitivity of CMB telescopes increases, the need for precise calibration becomes critical. Started in 2022, the COSMOCal project aims to place an artificial polarized sourc…
Blind mitigation of foreground-induced biases on primordial modes for ground-based CMB experiments
Aliza Mustafa, Alessandro Carones, Nicoletta Krachmalnicoff +2
Observations of the Cosmic Microwave Background (CMB) B-mode polarisation provide a unique probe of inflationary physics. Extracting a reliable constraint on the tensor-to-scalar r…
Revisiting model-independent constraints on spatial curvature and cosmic ladders calibration: updated and forecast analyses
Arianna Favale, Adrià Gómez-Valent, Marina Migliaccio
Model-independent approaches have gained increasing attention as powerful tools to investigate persistent tensions between cosmological observations and the predictions of CDM.…
A model-independent treatment of cosmic ladder calibration and measurement through low- observations
Arianna Favale, Adrià Gómez-Valent, Marina Migliaccio
Looking at the well-known Hubble tension as a tension in the calibrators of the cosmic distance ladder, i.e. the absolute magnitude of standard candles such as supernovae of Ty…
Quantification of 2D vs 3D BAO tension using SNIa as a redshift interpolator and test of the Etherington relation
Arianna Favale, Adrià Gómez-Valent, Marina Migliaccio
Several studies in the literature have found a disagreement between data on Baryon Acoustic Oscillations (BAO) derived using two distinct methodologies: the two-dimensional (2D or…
A cross-correlation analysis of CMB lensing and radio galaxy maps
Giulia Piccirilli, Marina Migliaccio, Enzo Branchini +1
We investigate the origin of the large clustering signal detected in the angular distribution of the radio sources in the TGSS catalog. To do so, we cross-correlate the angular pos…
