Kavli Affiliate: Nickolay Y. Gnedin | First 5 Authors: Ella Werre, David Robinson, Camille Avestruz, Nickolay Y. Gnedin, | Summary: Quasar absorption lines provide a unique window to the relationship between galaxies and the intergalactic medium during the Epoch of Reionization. In particular, high redshift quasars enable measurements of the neutral hydrogen content of the […]
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 […]
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 […]
