Logistics & Registration

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

Please register (free) at https://kicp-workshops.uchicago.edu/2020-CMB-S4/registration.php

Workshop Overview

This, the 11th workshop in the series of twice yearly CMB-S4 workshops, will focus on the CMB-S4 science case in conjunction with other experiments and probes. A key goal of the workshop is to engage with the broad community that is addressing science topics similar to those being pursued with CMB-S4, but using different techniques. We will discuss how CMB-S4 measurements can be used to advance these science topics in unique and complementary ways, and work on exploring powerful joint analysis of CMB and other probes.

Most importantly, on the first day of the workshop there will be a plenary session dedicated to Anti-racism. This session will start with the acknowledgement that racism, especially anti-Black racism, exists systemically in STEM, in our field, and in our collaboration. A goal of the session will be to raise awareness of systemic racism in general, as well as in our field and in our actions. We will then discuss how we as individuals and as a collaboration can practice anti-racism. We most strongly encourage all collaboration members to participate in this plenary session.


On the first day of the workshop (Monday August 10th) after the collaboration/project update, there will be a plenary session dedicated to Anti-racism.

A goal of the session will be to raise awareness of systemic racism in general, as well as in our field and in our actions. We will then discuss how we as individuals and as a collaboration can practice anti-racism. We most strongly encourage all collaboration members to participate in this plenary session.

The science programs (listed below and on the workshop web pages) are scheduled for Tuesday through Thursday, with typically 3 topics covered each day. The program for each science topic are being organized by two Rapporteurs, one being an expert in the field from outside our collaboration, and the other being an expert from the CMB-S4 collaboration. The structure of each science program is as follows:

  • a short (15+5 min) presentation by the CMB expert in the morning plenary session, to provide an overview of how CMB-S4 contributes to the science area, followed by
  • a parallel session (90 min) to discuss the larger context, including the complementarity of CMB-S4 with other probes, and to explore joint analysis of CMB and other probes, followed by

Please contact the organizers (listed below) for the science sessions in which you would like to participate.

Tuesday evening there will be an outreach event, "A Scientist Walks into a Bar.” More details on this event and how you can participate will be posted here soon.

Friday morning the Junior Scientist Advancement Committee (JSAC) will host a special session in which junior members are invited to give short presentation "job talks" (12+3 min) advertising their recent work. If you are interested in giving a talk, please sign by August 5th / here.

The workshop will end with a remote coffee/social sponsored by the JSAC on Friday.

The Science Topics, organizers / Rapporteurs

  • Synergies of Large Scale Structure Surveys with CMB-S4, Simone Ferraro, Chihway Chang, and Risa Weschler
    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 UniverseNathan Whitehorn and Kate Alexander
    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 Marilena Loverde, Zeeshan Ahmed, and Bryce Littlejohn
    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.
