Gravitational Waves and Cosmological Observables from First-Order Phase Transitions: Thermal Corrections at Low Temperature
Katharena Christy, James B. Dent, Sumit Ghosh +2
We consider the impact on cosmological first-order phase transitions (FOPTs) of low-temperature thermal corrections to the effective potential. These are corrections from degrees o…
Applying Simulation-Based Inference to Spectral and Spatial Information from the Galactic Center Gamma-Ray Excess
Katharena Christy, Eric J. Baxter, Jason Kumar
The two most favored explanations of the Fermi Galactic Center gamma-ray excess (GCE) are millisecond pulsars and self annihilation of the smooth dark matter halo of the galaxy. In…
Dark Matter Velocity Distributions: Comparing Numerical Simulations to Analytic Results
Katharena Christy, Jason Kumar, Louis E. Strigari
We test the consistency of dark matter velocity distributions obtained from dark matter-only numerical simulations with analytic predictions, using the publicly available Via Lacte…
Constraining -wave Dark Matter Annihilation with Gamma-ray Observations of M87
Katharena Christy, Jason Kumar, Pearl Sandick
We consider constraints on -wave dark matter in a dark matter spike surrounding the supermassive black hole at the center of M87. Owing to the large mass of the black hole, and…
