103. Invited talk by Jo Dunkley (Princeton University) on "Key future science goals from the CMB"
23/05/2022, 10:45

There is still a great deal to be learnt from CMB measurements. I will give an overview of science that the community hope to do with new data, from testing initial conditions of the universe to probing the dark sector and better understanding cosmic reionization and galaxy evolution. I will also describe some of the rich millimeter-wave science that can be done with these datasets, including...
104. Invited talk by Tomotake Matsumura (Kavli IPMU Tokyo) on "Scientific challenges expected from future space experiments"
23/05/2022, 11:25

The measurement of cosmic microwave background (CMB) from space is ideal for the entire sky access and broad observational frequency coverage. The past CMB satellite missions, COBE, WMAP, and Planck, play crucial roles in establishing modern cosmology. Now next-generation satellite missions will aim for even more demanding scientific goals, and the various corresponding requirements on the...

107. Invited talk by Anthony Challinor (Cambridge University) on "CMB probes of cosmological inflation: current status and future prospects"
23/05/2022, 14:00

The temperature and polarisation anisotropies of the CMB offer our most direct view of the early universe and their observation has, and continues to be, critical in constraining early-universe models. In this talk, I will review the key ways that the CMB constrains the properties of the primordial fluctuations, which were likely produced during an early period of cosmological inflation, and...
108. Invited talk by Jon Gudmundsson (Stockholm University) on "Knowing your beams"
23/05/2022, 14:40

The cosmic microwave background (CMB) has played a foundational role in the establishment of the standard model of cosmology. Driven by significant technological advances, future CMB experiments aim to make dramatic strides in our understanding of the universe. Some of our most ambitious efforts, however, run the risk of being hamstrung by poorly-understood instrument effects, systematics. A...

23/05/2022, 16:40

The tantalizing science reach of CMB observations has driven remarkable innovation in superconducting detectors. Roughly two decades ago, CMB focal planes consisted of a few individually assembled detection channels. By use of modern micro-fabrication equipment and improved microwave design tools, today’s imaging focal planes consist of multiple-tiled, large-format wafers. A wafer may...

116. Invited talk by Charles R. Lawrence (NASA/JPL) on "Lessons from Planck Calibration for Future CMB Experiments"
24/05/2022, 09:00

Planck set new standards for calibration of CMB experiments. That was hard. Calibration of future experiments, which will require map noise levels of nanokelvin or better, will be much harder. I will discuss lessons learned in calibrating Planck for future experiments.

24/05/2022, 11:50

Observations of the cosmic microwave background provide us with a unique window on the early Universe, and great new insights are expected from the next generation of dedicated ground and space telescopes. While probing the elusive inflationary epoch may be the most sought-after objective of those missions, they will also shed some light on another poorly-known era of the early Universe: the...
123. Invited talk by Massimiliano Lattanzi (INFN Ferrara) on "Particle and energy composition of the Universe: Neutrinos, Light relics and Dark Matter"
24/05/2022, 14:00

The interaction between cosmology and particle physics has always been very fruitful. Cosmological observations provide a powerful mean to test particle physics theories, and to measure the properties of existing particles like neutrinos. At the same time, the solution to two long-standing mysteries in cosmology - the origin of dark matter and dark energy - might lie in physics beyond the...

25/05/2022, 09:00

In the recent years it has become clear how the contamination coming from Galactic and extra-Galactic emissions represents one of the main limiting factor for any new science achievable with Cosmic Microwave Background observations. Having a thorough understanding of the foreground properties is therefore fundamental in order to achieve a reliable reconstruction of the clean CMB signal and to...
133. Invited talk by Mathieu Remazeilles (IFCA Santander) on "Next steps in component separation for new CMB observables"
25/05/2022, 09:30

Beyond the significant legacy of the ESA's Planck mission, the cosmic microwave background (CMB) radiation carries much more information that remains to be exploited in the coming decades. Next-generation CMB experiments of unprecedented sensitivity are being planned to extract and interpret new cosmological observables out of future CMB data. Among these new, yet undetected, cosmological...

26/05/2022, 09:00

All data analysis for an experiment is, at least implicitly, integrated. It all aims to distill scientific knowledge from a common data set. Whether the architects of the data reduction pipelines make the integration explicit is influenced by external constraints (processing power, availability of accurate models) and design strategy (highly modular or tightly coupled). Regardless of the case,...

We are expecting high-precision observations from upcoming CMB surveys, such as the Simons Observatory, CMB-S4, and LiteBIRD, as well as from future surveys of the large-scale structure, such as Euclid, Rubin LSST, SPHEREx, PSF, and Roman Space Telescope. Most of the observables from these independent surveys will be correlated due to their large overlaps in sky and redshift coverage. Joint...
