Inflationary interpretation of the gravitational-wave signal in the European Pulsar Timing Array DR2 with constraints
Philippe Turgeon, Chiara Caprini, Anton Chudaykin +5
The second data release of the European Pulsar Timing Array (EPTA) collaboration provides evidence for the presence of a gravitational-wave (GW) background. In this work, we explor…
LISA and the LISA Science Team
Anna Heffernan, Chiara Caprini, Neil Cornish +19
LISA, the Laser Interferometer Space Antenna, due to launch mid-2035, is a large class space mission by the European Space Agency (ESA). In partnership with NASA and ESA-member sta…
Fluid perturbations from expanding bubbles in first-order phase transitions
Chiara Caprini, Antonino S. Midiri, Simona Procacci +1
We study the power spectrum of the velocity field induced during a first-order phase transition occurring in the radiation-dominated era. We focus on the phase of bubble expansion,…
Reducing cosmological degeneracies by combining multiple classes of LISA gravitational-wave standard sirens
Danny Laghi, Nicola Tamanini, Alberto Sesana +6
We present the first joint gravitational-wave cosmological inference with LISA extreme mass-ratio inspirals at (galaxy redshifts) and massive black hole binaries at $z…
LISA and -ray telescopes as multi-messenger probes of a first-order cosmological phase transition
A. Roper Pol, A. Neronov, C. Caprini +2
We study two possible cosmological consequences of a first-order phase transition in the temperature range of 1 GeV to TeV: the generation of a stochastic gravitational wave…
Probing beyond the Standard Model with gravitational waves from phase transitions
Chiara Caprini
This review article is based on a seminar presented at the Higgs pairs workshop 2025. Stochastic gravitational wave backgrounds can serve as probe of the diverse phenomenology enco…
