Description
The Cosmic frontier includes probes of the fundamental nature of dark matter and dark energy, and opportunities using astrophysical and cosmological data to learn about fundamental physics.
CF1. Dark Matter: Particle-like
- CSS Parallel Slides CF1 (Jul. 18)
- CSS Parallel DM Comp. CF1/2/3/7 (Jul. 19)
- CSS Report Discussion Slides CF1 (Jul. 20)
This group covers dark matter in the regime where it appears in experiments as individual quanta, rather than coherently via wave phenomena. Techniques to search for such particles include directly through its interaction with detector materials, indirectly from products of its annihilation, and via production at accelerators (primarily covered in other frontiers).
CF2. Dark Matter: Wave-like
- CSS Parallel Slides CF2 (Jul. 18)
- CSS Parallel DM Comp. CF1/2/3/7 (Jul. 19)
- CSS Report Discussion Slides CF2 (Jul. 20)
This group covers low mass bosonic dark matter in the regime where it appears in experiments coherently via wave phenomena rather than as individual quanta. Examples include the QCD axion and more general axions, dark photons, and scalar dark matter. Current experimental techniques include broadband and resonant searches via cavities, circuit oscillators, NMR, utilizing low noise readout with quantum sensing and amplification technologies.
CF3. Dark Matter: Cosmic Probes
- CSS Parallel Slides CF3 (Jul. 18)
- CSS Parallel DM Comp. CF1/2/3/7 (Jul. 19)
- CSS Report Discussion Slides CF3 (Jul. 20)
This group covers properties of dark matter that can be uniquely probed by cosmological and astrophysical observations. Techniques include measurements of the cosmological distribution of dark matter, as well as studies of astrophysical objects in extreme environments. Examples of dark matter models probed through these techniques are warm dark matter, self-interacting dark matter, ultra-light axions, and primordial black holes.
CF4. Dark Energy and Cosmic Acceleration: The Modern Universe
This group covers cosmic probes of cosmology in the Modern Universe, when galaxies are fully formed. These probes include galaxy clusters, galaxy clustering, redshift space distortions, gravitational lensing, baryonic acoustic oscillations, supernovae and more. Spectroscopic, broad-band and multi-wavelength surveys are examples of experiments that will be primarily discussed in this working group. Other examples include projects involving CMB, 21cm, and gravitational wave observations.
CF5. Dark Energy and Cosmic Acceleration: Cosmic Dawn and Before
This group covers cosmic probes of cosmology in the early Universe from Inflation Era through the Cosmic Dawn. Subtopics include: growth of structure probes (e.g. 21cm power spectrum in the dark ages), probes of expansion history (e.g. BAO with black hole mergers, CMB), primordial non-gaussianity and inflation. High-z gravitational wave observatories, 21cm and CMB projects are examples of experiments expected to be primarily discussed here. Overlaps with the previous section are expected.
CF6. Dark Energy and Cosmic Acceleration: Complementarity of Probes and New Facilities
This group covers the connections between probes across multiple axes including combined probes across the early/late time regimes, and plans for future observatories/facilities to maximize the science outputs for Dark Energy and Cosmic Acceleration physics. Discussions about multimessenger projects (including GW, and Neutrinos) and new physics opportunities not included in the early/late universe topics are also welcome here.
CF7. Cosmic Probes of Fundamental Physics
- CSS Parallel Slides CF7 (Jul. 19)
- CSS Parallel DM Comp. CF1/2/3/7 (Jul. 19)
- CSS Report Discussion Slides CF7 (Jul. 20)
CF7 covers cosmic probes of fundamental physics topics beyond Dark Matter and Dark Energy using gravitational waves, cosmic rays, gamma rays, and neutrinos, as well as their combined studies to facilitate the multi-messenger science. This includes measurements of neutrino properties from cosmology (overlap with NF 5), tests of general relativity, emergent spacetime (overlap with CF2, 3, 5), black hole information with gravitational waves, the tension between local distance ladder measurements and cosmic microwave background estimates of the Hubble constant, equation of state of dense nuclear matter and hadron-quark gluon phase transitions, particle acceleration in astrophysical environments, bread-and-butter perturbative QCD and hadronic physics of extensive air showers, Lorentz Invariance Violation, search for evaporating primordial black holes, and exotic particles such as SUSY q-balls and axions.

Multi-Messenger White Paper Meeting
Details
There will be a kickoff workshop for the Multi-Messenger White Paper on Nov 5, 11a-12:30p Eastern Time. This paper is lead by Tonia Venters (tonia.m.venters@nasa.gov), Tiffany Lewis, Kristi Engel, and Marco Muzio. (Zoom link: TBA).
Agenda: We will spend about 5 min going over the working outline (attached), then spend the rest of the time in discussion. We are hoping people in attendance will volunteer to take sections to write and that the discussion will help to finalize the outline. For anyone not able to attend, our Snowmass slack channel is #wp-cf07-multi-messenger.CF4 Meeting
