Relativistic SZ maps and electron gas temperature spectroscopy
Mathieu Remazeilles
While third-generation CMB experiments have allowed to release the first maps of Compton- distortion due to thermal Sunyaev-Zeldovich (SZ) effect, next-generation CMB experiment…
In-flight polarization angle calibration for LiteBIRD: blind challenge and cosmological implications
Nicoletta Krachmalnicoff, Tomotake Matsumura, Elena de la Hoz +67
We present a demonstration of the in-flight polarization angle calibration for the JAXA/ISAS second strategic large class mission, LiteBIRD, and estimate its impact on the measurem…
Leverage on small-scale primordial non-Gaussianity through cross-correlations between CMB -mode and -distortion anisotropies
Mathieu Remazeilles, Andrea Ravenni, Jens Chluba
Multi-field inflation models and non-Bunch-Davies vacuum initial conditions both predict sizeable non-Gaussian primordial perturbations and anisotropic -type spectral distortion…
Interplanetary Dust as a Foreground for the LiteBIRD CMB Satellite Mission
K. Ganga, M. Maris, M. Remazeilles
As ever-more sensitive experiments are made in the quest for primordial CMB B Modes, the number of potentially significant astrophysical contaminants becomes larger as well. Therma…
The Simons Observatory: Constraining inflationary gravitational waves with multi-tracer B-mode delensing
Toshiya Namikawa, Anton Baleato Lizancos, Naomi Robertson +32
We introduce and validate a delensing framework for the Simons Observatory (SO), which will be used to improve constraints on inflationary gravitational waves (IGWs) by reducing th…
The BINGO Project V: Further steps in Component Separation and Bispectrum Analysis
Karin S. F. Fornazier, Filipe B. Abdalla, Mathieu Remazeilles +20
Observing the neutral hydrogen distribution across the Universe via redshifted 21cm line intensity mapping constitutes a powerful probe for cosmology. However, the redshifted 21cm…
The BINGO Project IV: Simulations for mission performance assessment and preliminary component separation steps
Vincenzo Liccardo, Eduardo J. de Mericia, Carlos A. Wuensche +21
The large-scale distribution of neutral hydrogen (HI) in the Universe is luminous through its 21 cm emission. The goal of the Baryon Acoustic Oscillations from Integrated Neutral G…
The BINGO Project II: Instrument Description
Carlos A. Wuensche, Thyrso Villela, Elcio Abdalla +41
The measurement of diffuse 21-cm radiation from the hyperfine transition of neutral hydrogen (HI signal) in different redshifts is an important tool for modern cosmology. However,…
The BINGO Project I: Baryon Acoustic Oscillations from Integrated Neutral Gas Observations
Elcio Abdalla, Elisa G. M. Ferreira, Ricardo G. Landim +43
Observations of the redshifted 21-cm line of neutral hydrogen (HI) are a new and powerful window of observation that offers us the possibility to map the spatial distribution of co…
Baryon Acoustic Oscillations from Integrated Neutral Gas Observations: an instrument to observe the 21cm hydrogen line in the redshift range 0.13 z 0.45 -- status update
Carlos A. Wuensche, Elcio Abdalla, Filipe Batoni Abdalla +48
BINGO (BAO from Integrated Neutral Gas Observations) is a unique radio telescope designed to map the intensity of neutral hydrogen distribution at cosmological distances, making th…
PACT. II. Pressure profiles of galaxy clusters using Planck and ACT
E. Pointecouteau, I. Santiago-Bautista, M. Douspis +9
The pressure of hot gas in groups and clusters of galaxies is a key physical quantity, which is directly linked to the total mass of the halo and several other thermodynamical prop…
Overview of the Medium and High Frequency Telescopes of the LiteBIRD satellite mission
L. Montier, B. Mot, P. de Bernardis +232
LiteBIRD is a JAXA-led Strategic Large-Class mission designed to search for the existence of the primordial gravitational waves produced during the inflationary phase of the Univer…
LiteBIRD: JAXA's new strategic L-class mission for all-sky surveys of cosmic microwave background polarization
M. Hazumi, P. A. R. Ade, A. Adler +233
