Detecting Gravitational-Wave Anisotropies with Simulation-Based Inference
Anna-Malin Lemke, Andrea Mitridate, Thomas Konstandin +2
Over the last five years, multiple Pulsar Timing Array (PTA) collaborations have reported mounting evidence for a gravitational-wave background (GWB) at nanohertz frequencies. Meas…
A positive definite formulation of vacuum decay with reduced symmetry
José R. Espinosa, Ryusuke Jinno, Thomas Konstandin +2
The Euclidean bounce for vacuum decay enjoys an symmetry that is lost in the presence of impurities than can catalyze the decay. We present a formulation for the calculation…
Slow-down of expanding bubbles in the early Universe
Nabeen Bhusal, Simone Blasi, Thomas Konstandin +2
We study slow-down effects for bubbles formed in a cosmological first-order phase transition (PT) focusing on deflagrations and hybrids, where the bubble wall is preceded by a shoc…
Tuning the violins: dark sector phase transition models for the PTA signal
Torsten Bringmann, Thomas Konstandin, Jonas Matuszak +2
First-order phase transitions in a dark sector have been invoked as an intriguing possibility to explain the observed stochastic gravitational wave background at nanohertz frequenc…
Scalar damping in cosmological phase transitions
Andreas Ekstedt, Thomas Konstandin, Jorinde van de Vis
We outline how to calculate the scalar damping term during a cosmological phase transition from kinetic theory. We determine the scalar damping rate from top quarks and weak gauge…
Prospects and Limitations of PTAs Anisotropy Searches -- The Frequentist Case
Thomas Konstandin, Anna-Malin Lemke, Andrea Mitridate +1
Recent findings from several Pulsar Timing Array (PTA) collaborations point to the existence of a Gravitational Wave Background (GWB) at nanohertz frequencies. A key next step towa…
