QUIJOTE scientific results - XX. Commissioning and First Results from the Thirty and Forty Gigahertz Instrument (TFGI)
M. Fernández-Torreiro, J. A. Rubiño-Martín, R. T. Génova-Santos +16
We present the commissioning and first results of the Thirty and Forty Gigahertz Instrument (TFGI), which observes the sky at 31 and 41 GHz with angular resolutions of 21' and 18'…
GroundBIRD: First On-Sky Responsivity Calibration at the Teide Observatory
Alessandro Fasano, Yonggil Jo, Ricardo Tanausú Génova-Santos +12
GroundBIRD is a cosmic microwave background (CMB) experiment located at the Teide Observatory (altitude m, Spain) designed to measure large-angular-scale intensity and p…
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…
Addressing Synchrotron Challenges for CMB Observations: ELFS-SA Collaboration for Robust Foreground Removal
E. de la Hoz, A. Mennella, K. Arnold +17
Upcoming cosmic microwave background (CMB) experiments aim to detect primordial gravitational waves with unprecedented sensitivity. Effective foreground removal is essential to avo…
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…
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…
