The Spectroscopic Stage-5 Experiment

Kavli Affiliate: Joshua Frieman | First 5 Authors: Robert Besuner, Arjun Dey, Alex Drlica-Wagner, Haruki Ebina, Guillermo Fernandez Moroni | Summary: Observational cosmology has provided an extraordinary perspective on our universe and our place within it. However, as our understanding of the universe has increased, some glaring holes in our knowledge have become apparent: What […]

Direct Detection of Ultralight Dark Matter via Charged Lepton Flavor Violation

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 […]

Illuminating the Physics of Dark Energy with the Discovery Simulations

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 […]

The Stochastic Siren: Astrophysical Gravitational-Wave Background Measurements of the Hubble Constant

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 […]

One-loop Renormalization of BPS String Masses in Pseudo-anomalous Heterotic String

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 […]
