CMB B-mode - NEXT

Jan 27, 2025, 9:30 AM → Jan 29, 2025, 6:00 PM Asia/Tokyo

Seminar Hall (KEK, Tsukuba - Building 3)

Guillaume Patanchon (ILANCE), Masaya Hasegawa (KEK-IPNS)

This workshop is organized as a collaboration between:

1. CMB-Inflate program - funded by European Union’s Horizon 2020 research and innovation programme under the Marie Skłodowska-Curie grant agreement No 101007633,
2. JSPS Core-to-core Program - Exploration of the origin and evolution of matter and space time: a research consortium for cosmic microwave background, PI Akito Kusaka,
3. The KEK Institute of Particle and Nuclear Studies KEK-IPNS,
4. The International Center for Quantum-field Measurement Systems for Studies of the Universe and Particles WPI-QUP.

The goals of this workshop are:

1. Review the latest results in CMB science
2. Define synergies between space-based and ground-based CMB measurements, data analysis, component separation and instrument development and modeling.
3. Following the core principles of the CMB-Inflate and Core-to-core programs, create strong international bonds between researchers and promote younger generations.

7 IPNS Seminar: Observing the First Light in the Universe, from the Earth and from the Sky

Since Penzias and Wilson discovered the cosmic microwave background (CMB) in 1964, observation of CMB has been central to the development of modern and precision cosmology. Combined with other probes, it has told us so many things about the Universe - how the Universe began, how the Universe has evolved, what the universe is made of, and still, how many questions are unsolved about the Universe. Throughout its history, the CMB observation has gone through a unique progression - ground-based telescopes, balloon-borne telescopes, and space missions have helped one another and contributed to scientific advancement in their own ways. I am new to the field compared to the history, and I may be out of my depth, but I will make my attempt to review this history and the nature of the CMB observation to realize the synergy between the observations from the ground and the sky. This leads us to the discussion relevant today: how the CMB observations from the ground and the sky may work together now and in the future. I will review the synergies and complementarity between these different approaches, with a focus on CMB polarization measurements, and conclude with a promising outlook for the field.
