The integrated 3-point correlation function (i3PCF) is a higher-order statistic (beyond traditional 2-point methods) that can be measured directly from weak lensing cosmic shear data by correlating local 1-point aperture mass statistics with local shear 2-point correlation functions (2PCF) measured within well-defined patches across a galaxy survey footprint. We have developed an accurate...
A framework to describe long-distance dynamics of an electroweak phase transition is offered by fluctuating hydrodynamics. In this setup the neutral Higgs component can be modelled to evolve according to a Langevin equation. In this talk we report on recent results for the thermal Higgs interaction rate close to a first order EW phase transition, which appears as a coefficient in a Langevin...
Over a combination of large areas as well as smaller, deep fields observations, the LOFAR Two-metre sky survey (LoTSS, Tasse+ 2021, Sabater+ 2021, Shimwell+ 2022) is producing detailed knowledge of sources at low radio frequencies (144 MHz), across large periods of cosmic time. The combined area of these surveys as well as their depth and ancillary information provides exciting opportunities...
A cosmological first-order phase transition during the evolution of the Universe can give rise to intriguing phenomena like electroweak baryogenesis or the generation of a stochastic background of gravitational waves through bubble nucleation. This study aims at exploring critical aspects of the bubble wall velocity, which significantly impact these phenomena. Recent investigations have...
