Inspiralling Binary merger parameter reconstruction with lunar and satellite Laser Ranging
Miguel Vanvlasselaer
Precision tracking of Earth--Moon and Earth--satellite ranges offers a novel, low-frequency avenue for detecting gravitational waves from inspiralling massive black hole binaries,…
GUEST: Gravitational Universe Exploration with Satellite Tracking. A passive satellite laser-ranging mission for the dark gravitational Universe
Diego Blas, Aurélien Hees, F. Javier Atapuerca +78
GUEST is a space mission concept whose central objective is the detection of gravitational waves (GWs) in the microhertz band -- a physics-rich frequency window that no other prese…
Dynamical evolution of the pressure on the bubble wall
Benoit Laurent, Miguel Vanvlasselaer
First-order phase transitions in the early Universe are pivotal for gravitational wave production, baryogenesis, and dark matter generation. A central question is whether bubble wa…
Spontaneous Baryogenesis from Axions on Induced Electroweak Walls
Miguel Vanvlasselaer, Wen Yin
We propose a baryogenesis mechanism in which an electroweak phase boundary is induced by a wall-like configuration of a scalar field, such as a domain wall or a shock wave, coupled…
Baryogenesis from Exploding Primordial Black Holes
Alexandra P. Klipfel, Miguel Vanvlasselaer, Sokratis Trifinopoulos +1
Exploding primordial black holes can source baryon asymmetry soon after the electroweak phase transition, as high-energy Hawking radiation drives ultrarelativistic shocks in the su…
Shocks from Exploding Primordial Black Holes in the Early Universe
Miguel Vanvlasselaer, Sokratis Trifinopoulos, Alexandra P. Klipfel +1
We investigate how Hawking radiation from low-mass primordial black holes deposits energy into the early-universe plasma and show that the resulting phenomena are hydrodynamic rath…
The Dark Side of the Moon: Listening to Scalar-Induced Gravitational Waves
D. Blas, J. W. Foster, Y. Gouttenoire +4
The collapse of large-amplitude primordial curvature perturbations into planetary-mass primordial black holes generates a scalar-induced gravitational wave background in the Hz…
Domain walls in the scaling regime: Equal Time Correlator and Gravitational Waves
Simone Blasi, Alberto Mariotti, Aäron Rase +1
Domain walls are topological defects that may have formed in the early Universe through the spontaneous breakdown of discrete symmetries, and can be a strong source of gravitationa…
Gravitational waves from the sound shell model: direct and inverse phase transitions in the early Universe
Giulio Barni, Simone Blasi, Eric Madge +1
Cosmological phase transitions are a frequent phenomenon in particle physics models beyond the Standard Model, and the corresponding gravitational wave signal offers a key probe of…
Un avenir commun au sein de la société numérique
Miguel Vanvlasselaer
Today, data and information have become overabundant resources within a global network of machines that exchange signals at speeds approaching that of light. In this highly saturat…
Implications for Pulsar Timing Arrays of Sub-solar Black Hole Detections: From LVK to Einstein Telescope and Cosmic Explorer
Yann Gouttenoire, Sokratis Trifinopoulos, Miguel Vanvlasselaer
The detection of compact binary mergers with sub-solar masses at gravitational-wave observatories could mark the groundbreaking discovery of primordial black holes (PBHs). Concurre…
CP-violation in production of heavy neutrinos from bubble collisions
Martina Cataldi, Kristjan Müürsepp, Miguel Vanvlasselaer
First order phase transitions (FOPT) in the early Universe can be powerful emitters of both relativistic and heavy particles, upon the collision of ultra-relativistic bubble shells…
Bubble wall dynamics from nonequilibrium quantum field theory
Wen-Yuan Ai, Matthias Carosi, Bjorn Garbrecht +2
We derive the coupled dynamics between the bubble wall and the plasma from first principles using nonequilibrium quantum field theory. The commonly used equation of motion of the b…
The Science of the Einstein Telescope
Adrian Abac, Raul Abramo, Simone Albanesi +485
Einstein Telescope (ET) is the European project for a gravitational-wave (GW) observatory of third-generation. In this paper we present a comprehensive discussion of its science ob…

Alberto Mariotti, Xander Nagels, Aäron Rase +1
Axionic domain walls, as they move through the early universe plasma during their collapse, can generate a net baryon and lepton number through the mechanism of spontaneous baryoge…
Photo-production of axions and neutrinos in compact objects
