I will present recent progress in applying effective field theory (EFT) to the precise computation of thermal phase transition parameters and the associated gravitational wave spectra. I will also briefly comment on byproducts of this work, including new methods for two-loop renormalization in EFT that avoid gauge-breaking counterterms and infrared rearrangement.

The matter-antimatter asymmetry of the Universe represents one of the main open questions in particle physics and cosmology. In this talk, we will present a novel realization of cold baryogenesis (a mechanism involving the formation and decay of topological defects associated with the gauge group of the Standard Model known as SU(2) textures) that relies on the out-of-equilibrium dynamics...

High-energy colliders probe fundamental interactions through direct searches and precision measurements. Yet conventional observables, such as total cross sections and asymmetries do not fully exploit the intrinsically quantum nature of multi-particle final states. A density matrix based description of scattering processes provides access to genuinely quantum observables, offering...

Gravitational waves at kilohertz and higher frequencies provide a unique window onto the early Universe at energy scales far beyond those accessible through the cosmic microwave background, potentially probing physics well above the electroweak scale. Yet existing detector concepts fall many orders of magnitude short of the big-bang nucleosynthesis bound on a stochastic gravitational-wave...

Over the past decade, LIGO/Virgo/KAGRA have given us abundant evidence for gravitational waves emitted by binary systems. But binaries can also absorb gravitational waves, leaving potentially detectable imprints on their orbits. In this talk, I will describe how this effect can be used to search for gravitational waves at frequencies that are inaccessible to all other current and future...

Neutrinos of cosmological origin are the second most numerous particles in the universe since billions of years. They are very difficult to measure directly, but we have several indirect (although very clear) indications of their presence. The strongest upper bounds on neutrino masses come from cosmological observations. I will discuss their model-dependence and robustness, given the existence...

We derive the shockwave metric in four-dimensional Einstein-Maxwell effective field theory (EFT) by performing an ultra-relativistic boost of the charged black hole solution accompanied by a rescaling of its mass and charge, including leading order EFT corrections. In contrast to the neutral (Schwarzschild) case, where higher derivative operators leave the shockwave geometry unchanged, we show...

Our recent numerical work has shown the importance of including non-linear effects that modify the gravitational sector in the strong field regime in beyond GR theories and dark matter environments. Advances in mathematically well posed formulations, numerics and data analysis mean that we can now extend our studies and stress-test current diagnostic and modelling tools with fully consistent...

Bosonic stars are hypothetical compact objects composed of ultralight bosonic fields and have been proposed as viable dark matter candidates. In this talk, I will present recent advances in our understanding of their stability properties and nonlinear dynamics based on numerical-relativity simulations. In particular, I will discuss gravitational synchronization effects that can arise when...

A huge fraction of the signals that could in principle be hiding in LHC data is still unexplored. The difficulty in extracting them is related to a long-standing statistical problem: how to perform a goodness-of-fit test in high-dimensional spaces. I will discuss two new ideas based on a geometric interpretation of collider data. They are completely orthogonal (in a colloquial sense) to...

Almost a century after its discovery, Dark Matter has not been identified yet. Even worse, the candidates that were more promising a few years/decades ago, those that the community was betting to find “just around the corner", have not shown up in the ever-improving searches. Hence theorists have gone back to the drawing board and restarted exploring a wider range of possibilities. Many new...

The earliest moments of our Universe, over 13 billion years ago, provide a unique laboratory for probing the interplay between gravity and quantum theory through observation. In particular, precise measurements of the Cosmic Microwave Background point towards a rapid inflationary expansion of spacetime, through which vacuum quantum fluctuations seeded the cosmic structures we observe...

Axion inflation with a pseudo-scalar coupling to gauge fields can give rise to a rich phenomenology, including gravitational waves over a broad range of frequencies and primordial black holes. Interesting signals are often reached in a regime in which the gauge fields produced by the rolling axion significantly backreact on the axion dynamics. While this effect was originally computed...

Machine learning is not only transforming our lives, but also particle theory. I will start by defining something like physics-specific representation learning, with a focus on theory aspects, and give examples how we can use learned representations to improve simulations, include networks in a statistical framework, and properly understand what they learn. Finally, I will briefly show how an...

Our Universe is still largely a mystery. Elusive dark matter shapes cosmic structures, while the Universe expands at a rate that we struggle to understand. Unraveling these fundamental open questions demands a deeper look into the distant cosmos, where gravitational waves from stellar-mass binary black holes offer a unique window of observation.
Unlike electromagnetic signals, gravitational...

Light travelling through the Universe is deflected by the intervening gravitational fields, a phenomenon known as gravitational lensing. This effect was an early prediction of General Relativity (GR) and it has become an essential tool in astronomy. The existence of gravitational
