29. LiteBIRD/MHFT Bread-Board testing

Prof. Cristian Franceschet (Università degli Studi di Milano)

We present the optical calibration strategy of the Medium-High Frequency Telescope on-board the LiteBIRD satellite, the JAXA’s space mission targeting the detection of the imprint of primordial gravitational waves on the Cosmic Microwave Background.
For its purpose, LiteBIRD is endowed with unprecedent sensitivity, guaranteed by two independent instruments, the Low Frequency Telescope (LFT)...

30. Effect of Half-Wave Plate systematics on the estimate of r

A rotating Half-Wave Plate (HWP) is included in the design of future CMB experiments, such as LiteBIRD. A realistic HWP is characterised by frequency-dependent non-idealities (i.e. efficiency, non-ideal phase
shift, cross-polarization) that are measured within a certain error. We simulate how uncertainties in the determination of the aforementioned non-idealities affect estimates of the...

31. Characterization of the Optical System of the LSPE‐STRIP Instrument

Sabrina Realini (Università degli Studi di Milano)

We present the analysis of the optical system of the STRIP instrument, the ground-based telescope of the Large Scale Polarization (LSPE) experiment, which aims at polarization measurements of the Cosmic Microwave Background on large angular scales.
STRIP will observe the polarized emission from the ``Observatorio del Teide” in Tenerife, starting in late 2021. The instrument consists of an...

32. The Effects of Instrumental Systematics on CMB Lensing Reconstruction

Mark Mirmelstein (University of Sussex)

The weak gravitational lensing of the CMB is an important cosmological tool that allows us to learn more about the structure, composition and evolution of the Universe. Upcoming CMB experiments, such as the Simons Observatory, will provide the most high-resolution and low-noise CMB measurements to date, from which we could reconstruct the lensing potential to unparalleled precision. To achieve...

33. Towards an Atacama Large Aperture Submillimeter Array (AtLAST)

Dr Tony Mroczkowski (ESO)

Astrophysical observations at (sub-)mm wavelengths (λ from ~300 μm to ~3mm) allow us to study the cold and dense material in the Universe, hence probing the formation of stars and planets, and the interstellar and circumgalactic medium of galaxies across all cosmic times. The current generation of 10-meter-class single dish telescopes has delivered some of the first surveys at (sub-)mm...
