Cosmology with the Laser Interferometer Space Antenna / LISA Cosmology Working Group Collaboration
The Laser Interferometer Space Antenna (LISA) has two scientific objectives of cosmological focus: to probe the expansion rate of the universe, and to understand stochastic gravitational-wave backgrounds and their implications for early universe and particle physics, from the MeV to the Planck scale. However, the range of potential cosmological applications of gravitational wave observations extends well beyond these two objectives. [...]

Detection of Early-Universe Gravitational Wave Signatures and Fundamental Physics / Caldwell, Robert (Dartmouth Coll.) ; Cui, Yanou (UC, Riverside) ; Guo, Huai-Ke (U. Utah, Salt Lake City) ; Mandic, Vuk (Minnesota U.) ; Mariotti, Alberto (Brussels U., IIHE) ; No, Jose Miguel (Madrid, IFT) ; Ramsey-Musolf, Michael J.

Detection of a gravitational-wave signal of non-astrophysical origin would be a landmark discovery, potentially providing a significant clue to some of our most basic, big-picture scientific questions about the Universe. In this white paper, we survey the leading early-Universe mechanisms that may produce a detectable signal -- including inflation, phase transitions, topological defects, as well as primordial black holes -- and highlight the connections to fundamental physics.

Non-Gaussianity from Self-Ordering Scalar Fields / Figueroa, Daniel G. (CERN ; Madrid, IFT) ; Caldwell, Robert R. (Dartmouth Coll.) ; Kamionkowski, Marc (Caltech)
The Universe may harbor relics of the post-inflationary epoch in the form of a network of self-ordered scalar fields. Such fossils, while consistent with current cosmological data at trace levels, may leave too weak an imprint on the cosmic microwave background and the large-scale distribution of matter to allow for direct detection.
