Meeting Info & Registration

Due to the ongoing COVID-19 pandemic this workshop will be held remotely, August 10th - 14th 2020.

Registration details will follow shortly.

Workshop overview

This workshop will be focused on the CMB-S4 science case in conjunction with other experiments and probes. The SOC currently is developing programs on the following science topics:

  • Synergies of Large Scale Structure Surveys with CMB-S4
    We will focus on the synergies of combining tracers of large scale structure as measured at radio through X-ray wavelengths with the wide-field CMB-S4 survey, which will cover ~70% of the sky. We are particularly interested in exploring cosmological analyses that can only be done via the combination of multi-wavelength probes or that are significantly improved through the use of multiple probes (e.g., Nx2 pt, kSZ cosmology, CMB lensing tomography, cosmic shear/WL calibration, cluster cosmology, etc).
  • Exploiting the mm-wave window on the Transient Universe
    CMB-S4 will open a new window onto the mm-wave transient sky, enabling new synergies with multimessenger astrophysics and time-domain astronomy in the coming decade. This session will be devoted to exploring those synergies and the survey landscape in the coming decade.
  • Complementarity of Cosmological and Beamline Neutrino Experiments
    Over the next decade, a number of cosmological and terrestrial experiments will measure key properties of neutrinos including the neutrino mass scale and ordering, search for the existence of sterile neutrinos, and probe the generation mechanism of neutrino masses. This session will explore how these measurements can complement each other to fill out our picture of neutrino physics over the next decade, focusing on how CMB-S4 measurements of neutrino number and mass relate to, and can inform, other cosmological and laboratory probes.
  • Shedding Light on the Dark Sector
    CMB-S4 will provide characteristically new insights into the physics of the dark sector across a wide range of mass, length, and coupling scales. We will discuss how CMB observations will complement and enhance other searches for dark sector physics. Topics will include means by which the CMB may provide insights for WIMPs and their interactions, light dark matter candidates such as axion-like particles, and light relics including dark radiation and relativistic species.
  • Dust and Magnetic fields in the Galaxy
    CMB-S4 will make sensitive, high-resolution measurements of the Galactic polarized dust and synchrotron emission. We will discuss opportunities to determine the composition of interstellar dust, understand the role of magnetic fields in molecular cloud and star formation, and characterize turbulence in the ISM.
  • Illuminating the Circumgalactic Medium (CGM)
    The next decade of mm-wave observations will transform our understanding of galaxy formation, driven by precisely measuring the thermodynamic properties of ionized gas, using the cosmic microwave background as a "backlight". In this session we will discuss how these observations will probe the CGM gas well into the outskirts of hitherto-unexplored high-redshift, low-mass systems and the synergies with other observables.
  • Astrophysics with High-Redshift Galaxies and Clusters
    CMB-S4 will detect high redshift dusty galaxies out to z~9; protoclusters out to z~5 ; and massive galaxy clusters out to z~2. In this session we will discuss how CMB-S4 can shed light on the evolution from high-redshift dusty galaxies to protoclusters to galaxy clusters and highlight the insights and advances that studies of these discrete objects will bring to the field of astrophysics.
  • Observing Cosmic Dawn
    Little is still known about the epoch of reionization as it continues to remain hidden from our view. In this session we will discuss what potential discoveries CMB observations will make about reionization and how it will approve our understanding of how stars, black holes, and galaxies first emerged. We will also discuss synergies with 21cm and intensity mapping observations.
