Surface Brightness Fluctuations in Two SPT clusters: a Pilot Study

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 […]

Inferring dark matter subhalo properties from simulated subhalo-stream encounters

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 […]

Hitting the Thermal Target for Leptophilic Dark Matter

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, […]

No need to know: astrophysics-free gravitational-wave cosmology

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 […]

NS5-brane backgrounds and coset CFT partition functions

Kavli Affiliate: Emil J. Martinec | First 5 Authors: Andrea Dei, Emil J. Martinec, , , | Summary: Worldsheet string theory is solvable for a variety of backgrounds involving Neveu-Schwarz fivebranes, in terms of gauged nonlinear sigma models on group manifolds. We compute the worldsheet torus partition function of these models, and propose gauging of […]
