Kavli Affiliate: Lindsey E. Bleem | First 5 Authors: Charles E. Romero, Massimo Gaspari, Gerrit Schellenberger, Bradford A. Benson, Lindsey E. Bleem | Summary: Studies of surface brightness fluctuations in the intracluster medium (ICM) present an indirect probe of turbulent properties such as the turbulent velocities, injection scales, and the slope of the power spectrum […]

Kavli Affiliate: Alexander P. Ji | First 5 Authors: Tariq Hilmi, Denis Erkal, Sergey E. Koposov, Ting S. Li, Sophia Lilleengen | Summary: In the cold dark matter paradigm, our Galaxy is predicted to contain >10000 dark matter subhaloes in the $10^5-10^8M_odot$ range which should be completely devoid of stars. Stellar streams are sensitive to […]
Kavli Affiliate: Gordan Krnjaic | First 5 Authors: Cari Cesarotti, Gordan Krnjaic, , , | Summary: We study future lepton collider prospects for testing predictive models of leptophilic dark matter candidates with a thermal origin. We calculate experimental milestones for testing the parameter space compatible with freeze-out and the associated collider signals at past, present, […]
Kavli Affiliate: Daniel E. Holz | First 5 Authors: Amanda M. Farah, Thomas A. Callister, Jose María Ezquiaga, Michael Zevin, Daniel E. Holz | Summary: Gravitational waves from merging compact objects encode direct information about the luminosity distance to the binary. When paired with a redshift measurement, this enables standard-siren cosmology: a Hubble diagram can […]

Kavli Affiliate: Craig Hogan | First 5 Authors: Craig Hogan, , , , | Summary: Cosmic structure on the largest scales preserves the pattern laid down by quantum fluctuations of gravity in the early universe on scales comparable to inflationary horizons. It is proposed here that fluctuations create physical correlations only within finite regions enclosed […]
Kavli Affiliate: Michael S. Turner | First 5 Authors: Michael S. Turner, , , , | Summary: The age of the Universe at a given redshift is a fundamental relationship in cosmology. For many years, the uncertainties in it were dauntingly large, close to a factor of 2. In this age of precision cosmology, they […]
