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 […]
