We present QUIJOTE intensity and polarization maps in four frequency bands centred
around 11, 13, 17, and 19 GHz, and covering approximately 29 000 deg2, including most of …

We present the constraints on the amplitude of magnetic fields generated prior to the
recombination using CMB temperature and polarization anisotropy data from Planck 2018 …

The report of a significant deviation of the CMB temperature anisotropies distribution from
Gaussianity (soon after the public release of the WMAP data in 2003) has become one of the …

This paper provides an overview of the Low Frequency Instrument (LFI) programme within
the ESA Planck mission. The LFI instrument has been developed to produce high precision …

Cosmology has entered an era where the experimental limitations are not due to
instrumental sensitivity but instead due to inherent systematic uncertainties in the …

Anomalous microwave emission (AME) is an important emission component between 10
and 60 GHz that is not yet fully understood. It seems to be ubiquitous in our Galaxy and is …

The QUIJOTE (QUI JOint Tenerife) CMB Experiment will operate at the Teide Observatory
with the aim of characterizing the polarisation of the CMB and other processes of Galactic …

The capability of Cosmic Inflation to explain the latest Cosmic Microwave Background and
Baryonic Acoustic Oscillation data is assessed by performing Bayesian model comparison …

Detecting the imprint of inflationary gravitational waves on the B-mode polarization of the
cosmic microwave background (CMB) is one of the main science cases for current and next …

In this paper, monolithic microwave integrated circuit (MMIC) broadband low-noise
amplifiers (LNAs) for cryogenic applications based on a 100-nm metamorphic high-electron …
