We consider the case of very low reheating scenarios [T-RH similar to O(MeV)] with a better calculation of the production of the relic neutrino background (with three-flavor oscillations). At 95% confidence level, a lower bound on the reheating temperature T-RH > 4.1 MeV is obtained from big bang nucleosynthesis, while T-RH > 4.7 MeV from Planck data (allowing neutrino masses to vary), the most stringent bound on the reheating temperature to date. Neutrino masses as large as 1 eV are possible for very low reheating temperatures.

Summary: This study presents forecasts for the joint analysis of Euclid and Cosmic Microwave Background (CMB) data, predicting the cosmological parameters of the standard cosmological model and its extensions. The addition of CMB data substantially impacts constraints for all cosmological parameters of the standard Λ-cold-dark-matter model, with improvements reaching up to a factor of ten. The results highlight the crucial importance of combining and cross-correlating Euclid probes with CMB data for cosmological constraints.

Summary: Measuring the polarization of the Cosmic Microwave Background is a significant aspect of current cosmological research, with LSPE being a program dedicated to this task. LSPE consists of two instruments, LSPE-Strip and LSPE-SWIPE, working together to detect the B-mode polarization component and potentially reveal the presence of gravitational waves from the early Universe. LSPE is expected to provide valuable insights into the inflationary theory and improve constraints on cosmological parameters.

Cosmic Microwave Background Polarization as a Tool to Constrain the Optical Properties of the Universe

Margherita Lembo, Massimiliano Lattanzi, Luca Pagano, Alessandro Gruppuso, Paolo Natoli, Francesco Forastieri

Summary: This study introduces a new formalism to describe the conversion between polarization states of radiation in the context of cosmology, known as the generalized Faraday effect (GFE). By applying this formalism to the cosmic microwave background (CMB) polarized anisotropy power spectra, the study provides insights into the potential implications of GFE on isotropy- and/or parity-violating physics. The research highlights the possibility of GFE inducing the conversion of linear polarization into circular polarization, and suggests observational bounds on GFE-induced CMB circularly polarized power spectrum.

Detailed study of HWP non-idealities and their impact on future measurements of CMB polarization anisotropies from space

S. Giardiello, M. Gerbino, L. Pagano, J. Errard, A. Gruppuso, H. Ishino, M. Lattanzi, P. Natoli, G. Patanchon, F. Piacentini, G. Pisano

Summary: This study investigates the impact of a specific class of instrumental systematics on the reconstruction of the B-mode power spectrum of the cosmic microwave background (CMB). The focus is on the non-ideal properties of the half-wave plate (HWP), which is a polarization modulator used in future CMB experiments. The effects of non-ideal HWP properties, such as transmittance, phase shift, and cross-polarization, are studied using a simulation pipeline adapted to the LiteBIRD mission. The systematic effects on the tensor-to-scalar ratio are quantified, and accuracy requirements for the measurements of HWP properties are derived.

Rubino-Martin, M. Sasaki, M. Shiraishi, G. Signorelli, S. Stever, A. Tartari, M. Tristram, M. Tsuji, L. Vacher, I. K. Wehus, M. Zannoni

Summary: We demonstrate the in-flight polarization angle calibration for the LiteBIRD strategic large class mission and assess its impact on the measurement of the tensor-to-scalar ratio parameter, r, using simulated data. Our calibration method relies on nulling the cross correlation of the polarized signal in each frequency channel. We find that angle miscalibration biases results obtained with parametric fitting methods but has less impact on algorithms that do not assume foreground properties. Both component separation algorithms result in unbiased estimation of the r parameter once the miscalibration angles are corrected. This work provides a robust framework for polarization experiments and offers insights for the design of future missions.

Estimating the local dark matter density in a non-axisymmetric wobbling disc

S. Sivertsson, J. Read, H. Silverwood, P. F. de Salas, K. Malhan, A. Widmark, C. F. P. Laporte, S. Garbari, K. Freese

Summary: This study evaluates the factors affecting the determination of the density of dark matter near the Sun (rho(DM, circle dot)), and finds that common approximations such as axisymmetry and a flat rotation curve can lead to significant systematic errors. However, including the tilt term and the rotation curve term in the analysis can provide an unbiased estimate of rho(DM, circle dot).

Neutrino mass and mass ordering: no conclusive evidence for normal ordering

Stefano Gariazzo, Martina Gerbino, Thejs Brinckmann, Massimiliano Lattanzi, Olga Mena, Thomas Schwetz, Shouvik Roy Choudhury, Katherine Freese, Steen Hannestad, Christoph A. Ternes, Mariam Tortola

Summary: The extraction of neutrino mass ordering is a major challenge in particle physics and cosmology. Recent claims regarding the preference for normal ordering of neutrino mass spectrum are investigated and no decisive evidence is found. The significance in favor of normal mass ordering is currently moderate, driven mostly by neutrino oscillation data.

Summary: The stability of particles in the cosmic soup can affect cosmic evolution. This work updates the constraints on the decaying cold dark matter scenario in the presence of effectively massless decay products. The study finds the most stringent upper limit on the decay rate of decaying cold dark matter particles to be Gamma(DCDM) < 0.129x10(-18) s(-1) (or tau(DCDM) > 246 Gyr) at 95% confidence level, using data from various cosmological probes.

Summary: LiteBIRD is a future satellite mission aimed at observing the polarization of cosmic microwave background radiation to study the inflationary universe. The mission will use three telescopes equipped with transition-edge sensor bolometers. This study estimated the instrumental sensitivity of LiteBIRD based on its current design, taking into account the detector noise from optical loadings as well as thermal carrier and readout noise. The observational sensitivities for fifteen bands specifically designed for LiteBIRD telescopes were calculated assuming a certain observation time efficiency.

Probing Lorentz-violating electrodynamics with CMB polarization

L. Caloni, S. Giardiello, M. Lembo, M. Gerbino, G. Gubitosi, M. Lattanzi, L. Pagano

Summary: We conducted a comprehensive study on the signatures of Lorentz violation in electrodynamics on the Cosmic Microwave Background (CMB) anisotropies. Using the minimal Standard Model Extension (SME) framework, we analyzed the effects generated by renormalizable operators, both CPT-odd and CPT-even. Constraints were placed on the relevant Lorentz-violating parameters using the latest CMB datasets. We obtained improved bounds on CPT-even coefficient and stronger limits on CPT-odd coefficients compared to previous CMB-based limits, providing the strongest constraints to date on CPT-violating coefficients in the minimal SME.

Non-unitary three-neutrino mixing in the early Universe

Stefano Gariazzo, Pablo Martinez Mirave, Olga Mena, Sergio Pastor, Mariam Tortola

Summary: Deviations from unitarity in three-neutrino mixing can affect the interactions of neutrinos with matter and have implications for the early Universe and the effective number of neutrinos, Neff. We calculate the energy density of radiation with a non-unitary neutrino mixing matrix, and discuss the potential impact on forthcoming cosmological observations. Accurate measurements of Neff can provide independent constraints on departures from unitarity.
