26. LiteBIRD Status

Ludovic Montier (IRAP)

25/11/2026 14:00

I will present the current status of the LiteBIRD JAXA mission, after it recently passed the Mission Definition Review at JAXA and it entered into project phase. A new exciting phase has just started, with a new instrumental design and enhanced science goals I will describe in more details.

33. CMB-probe

Jacques Delabrouille

The 2020 decadal survey in Astronomy and Astrophysics in the US (released in 2021) proposed a program of ground and space-based activities and recommended critical actions to carry-out its identified most compelling science goals. It stated that to address the major science questions identified by the Panel on Cosmology, the cosmic microwave background remains the single most important...

8. COSMOCal project: a calibrator for CMB experiments

Alessia RITACCO (CNRS-LPSC)

25/11/2026 15:20

Precise measurements of the Cosmic Microwave Background (CMB) polarization anisotropies are essential for probing fundamental physics, particularly through the search for primordial B-modes generated by inflationary gravitational waves and the investigation of cosmic birefringence, a potential signature of physics beyond the Standard Model. Achieving the required accuracy demands unprecedented...

13. Impact of Galactic dust complexity on calibration of future CMB space missions

The search for primordial gravitational waves imprinted in the polarization of the Cosmic Microwave Background (CMB) is a major scientific goal of next-generation CMB experiments. Achieving the sensitivity required to detect primordial B-modes demands precise control of instrumental systematics and a robust separation of the cosmological signal from astrophysical foregrounds. In particular,...
