Kavli Affiliate: Joshua Frieman | First 5 Authors: Robert Besuner, Arjun Dey, Alex Drlica-Wagner, Haruki Ebina, Guillermo Fernandez Moroni | Summary: The existence, properties, and dynamics of the dark sectors of our universe pose fundamental challenges to our current model of physics, and large-scale astronomical surveys may be our only hope to unravel these long-standing […]

Kavli Affiliate: Gordan Krnjaic | First 5 Authors: Innes Bigaran, Patrick J. Fox, Yann Gouttenoire, Roni Harnik, Gordan Krnjaic | Summary: We propose a dark matter direct-detection strategy using charged particle decays at accelerator-based experiments. If ultralight $(m_phi ll text{eV})$ dark matter has a misalignment abundance, its local field oscillates in time at a frequency […]

Kavli Affiliate: Katrin Heitmann | First 5 Authors: Gillian D. Beltz-Mohrmann, Adrian Pope, Alex Alarcon, Michael Buehlmann, Nicholas Frontiere | Summary: In this paper, we present the Discovery simulations: a new pair of high-resolution N-body simulations motivated by the DESI Y1 BAO cosmological constraints on dark energy. The Discovery simulations were run with identical initial […]

Kavli Affiliate: Daniel E. Holz | First 5 Authors: Bryce Cousins, Kristen Schumacher, Adrian Ka-Wai Chung, Colm Talbot, Thomas Callister | Summary: Gravitational waves from individually resolved compact object mergers can be used as standard sirens, offering a novel self-calibrating precision probe of cosmology. While the standard siren method has been well-explored, the gravitational-wave background […]
Kavli Affiliate: Jeffrey A. Harvey | First 5 Authors: Jeffrey A. Harvey, Tai Wai Hu, , , | Summary: Compactification of heterotic string on a Calabi-Yau threefold can lead to a four-dimensional low-energy effective theory which contains a $U(1)$ gauge theory which is pseudo-anomalous, meaning that the fermion content is anomalous, but that the fermion […]

Kavli Affiliate: Michael S. Turner | First 5 Authors: Matilde Lopes Abreu, Michael S. Turner, , , | Summary: The first year results of DESI provide evidence that dark energy may not be quantum vacuum energy ($Lambda$). If true, this would be an extraordinary development in the 25-year quest to understand cosmic acceleration. The best-fit […]
