Abstract

We introduce a new method for reconstructing the primordial power spectrum, P(k), directly from observations of the Cosmic Microwave Background (CMB). We employ Singular Value Decomposition (SVD) to invert the radiation perturbation transfer function. The degeneracy of the multipole l to wave number k linear mapping is thus reduced. This enables the inversion to be carried out at each point along a Monte Carlo Markov Chain (MCMC) exploration of the combined P(k) and cosmological parameter space. We present best-fit P(k) obtained with this method along with other cosmological parameters.

Constraints on cosmic birefringence using E-mode polarisation

Arefe Abghari, Raelyn M. Sullivan, Lukas T. Hergt, Douglas Scott

Summary: This paper investigates a method for exploring a birefringent universe through the rotation of the plane of polarization of cosmic microwave background photons. The authors propose an independent method for extracting the birefringence angle using only temperature and E-mode signals. They forecast that with an ideal experiment, a birefringence angle of 0.3 degrees can be constrained with 3 sigma statistical significance. Additionally, the authors explore the impact of systematic errors introduced by polarization efficiency and suggest this method as an additional way to verify claimed birefringence signatures derived from B modes.

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.

Characterization of the polarized synchrotron emission from Planck and WMAP data

F. A. Martire, R. B. Barreiro, E. Martinez-Gonzalez

Summary: This work characterizes the diffuse Galactic polarized synchrotron, the dominant foreground emission of cosmic microwave background (CMB) at low frequency. By analyzing the power spectra of EE, BB, and EB from polarization frequency maps, it is found that the spectral amplitude of EE and BB decays steeply with multipole, and B/E power asymmetry is confirmed. The study also shows that the EE and BB power-law model without EB cross-correlation can reasonably describe the diffuse synchrotron polarization emission if bright Galactic center and point sources are masked. The recovered spectral energy distribution (SED) indicates a steepening trend from low to high Galactic latitude.

Efficient ILC analysis on polarization maps after EB leakage correction

Zirui Zhang, Yang Liu, Si-Yu Li, De-Liang Wu, Haifeng Li, Hong Li

Summary: This study extends the Internal Linear Combination (ILC) method to analyze CMB polarization maps in ground-based experiments, successfully extracting a pure B map by combining it with a template cleaning method to eliminate the impact of EB leakage caused by partial sky coverage. The results demonstrate that this method effectively controls the level of foreground residual and improves the efficiency of component separation.

Impact of half-wave plate systematics on the measurement of cosmic birefringence from CMB polarization

Marta Monelli, Eiichiro Komatsu, Alexandre E. Adler, Matteo Billi, Paolo Campeti, Nadia Dachlythra, Adriaan J. Duivenvoorden, Jon E. Gudmundsson, Martin Reinecke

Summary: The study investigates the impact of the non-idealities of the half-wave plate (HWP) when used as a polarization modulator on the cosmic microwave background (CMB) angular power spectra. It is found that the HWP-induced angle could be misinterpreted as cosmic birefringence (CB). Accurate knowledge of the HWP is required to mitigate this issue, and the simulation and analytical formulae provided will help derive calibration accuracy requirements for the HWP.

A hybrid map-C? component separation method for primordial CMB B-mode searches

S. Azzoni, D. Alonso, M. H. Abitbol, J. Errard, N. Krachmalnicoff

Summary: The future ground-based and satellite-borne experiments hope to indirectly detect the signal from primordial tensor fluctuations through observing the polarised emission from the Cosmic Microwave Background (CMB). However, accurately separating the signal from polarised Galactic foregrounds is crucial. This study presents a component separation method for multi-frequency CMB observations that can effectively reduce contamination from Galactic foregrounds below an equivalent tensor-to-scalar ratio rFG <= 5x10-4.

Teply, Clara Verges, Edward J. Wollack, Zhilei Xu, Mario Zannoni

Summary: The calibration requirements for next-generation ground-based observatories targeting the large-angle B-mode polarization of the Cosmic Microwave Background were quantified, focusing on the Simons Observatory (SO). Results showed that knowing gain calibration and bandpass center frequencies to percent levels or less is crucial to avoid biases on the tensor-to-scalar ratio r. Additionally, a few tenths of a degree calibration for polarization angles and knowledge of their frequency variation between the band edges is essential for accurate measurements. These strict calibration requirements do not significantly degrade the final constraints on r.

Cross-correlation power spectra and cosmic birefringence of the CMB via photon-neutrino interaction

Roohollah Mohammadi, Jafar Khodagholizadeh, Mahdi Sadegh, Ali Vahedi, S. S. Xue

Summary: In the context of the standard model of particles, this study investigates the weak interaction between cosmic microwave background (CMB) and cosmic neutrino background (CvB). It discovers that non-vanishing TB and EB power spectra can be generated in the presence of scalar perturbation, which contradicts the standard cosmological scenario. By comparing the results with experimental data, significant information about the nature of CvB, including CMB-CvB forward scattering for TB, TE, and EB power spectra, can be obtained. The study also explores the anisotropic birefringent behavior and linear polarization rotation angle change caused by the cosmic neutrino background opacity.

Extracting cosmological parameters from N-body simulations using machine learning techniques

Andrei Lazanu

Summary: Machine learning techniques accurately extract cosmological parameters Omega(m) and sigma(8) from N-body simulations, and also find these parameters from the non-linear matter power spectrum using random forest regressors and deep neural networks. The power spectrum provides competitive results in terms of accuracy compared to using simulations, and the scalar spectral index ns can also be estimated from the power spectrum with lower precision.

Summary: This article presents the first linear polarization measurements from the 2015 long-duration balloon flight of Spider, which is an experiment designed to map the polarization of the cosmic microwave background (CMB) on degree angular scales. The results show detections of Galactic dust emission with high significance and employ two independent foreground-removal techniques to explore the sensitivity of the cosmological result. Upper limits on the primordial tensor-to-scalar ratio are derived, complementing the Planck polarization maps.

All-sky analysis of astrochronometric signals induced by gravitational waves

Sebastian Golat, Carlo R. Contaldi

Summary: We propose a unified spin-weighted formalism to describe the timing and astrometric perturbations induced by gravitational waves on astrophysical point sources. By utilizing spin-weighted spherical harmonics, this approach simplifies the interpretation and simulation of anisotropies induced by gravitational waves in observables. It also allows for a simplified derivation of angular cross-spectra and their connection to generalized Hellings-Downs correlation functions.

Comparison of maximum-likelihood mapping methods for gravitational-wave backgrounds

Arianna Renzini, Joseph D. Romano, Carlo R. Contaldi, Neil J. Cornish

Summary: Detection of a stochastic background of gravitational waves is likely to happen in the next few years. Different mapping methods have been proposed to target anisotropic backgrounds. This study compares the intensity mapping approach with the amplitude-phase mapping approach and finds that the latter is only applicable to phase coherent backgrounds. Therefore, intensity mapping is preferred for such backgrounds.
