The art of simulating the early Universe. Part III: Scalar-Gauge-Fluid Dynamics
Daniel G. Figueroa, Kenneth Marschall, Antonino S. Midiri +1
We discuss lattice methods for the simulation of fluid dynamics in the early Universe. This review represents a third entry in the monographic series on lattice cosmology technique…
Gravitational waves from first-order phase transitions in LISA: reconstruction pipeline and physics interpretation
Chiara Caprini, Ryusuke Jinno, Marek Lewicki +6
We develop a tool for the analysis of stochastic gravitational wave backgrounds from cosmological first-order phase transitions with LISA: we initiate a template databank for these…
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…
The second data release from the European Pulsar Timing Array: IV. Implications for massive black holes, dark matter and the early Universe
J. Antoniadis, P. Arumugam, S. Arumugam +111
The European Pulsar Timing Array (EPTA) and Indian Pulsar Timing Array (InPTA) collaborations have measured a low-frequency common signal in the combination of their second and fir…
Cosmology with the Laser Interferometer Space Antenna
Pierre Auclair, David Bacon, Tessa Baker +177
The Laser Interferometer Space Antenna (LISA) has two scientific objectives of cosmological focus: to probe the expansion rate of the universe, and to understand stochastic gravita…
Gravitational wave signal from primordial magnetic fields in the Pulsar Timing Array frequency band
Alberto Roper Pol, Chiara Caprini, Andrii Neronov +1
The NANOGrav, Parkes, European, and International Pulsar Timing Array (PTA) Collaborations have reported evidence for a common-spectrum process that can potentially correspond to a…
Leading-order nonlinear gravitational waves from reheating magnetogeneses
Yutong He, Alberto Roper Pol, Axel Brandenburg
We study the leading-order nonlinear gravitational waves (GWs) produced by an electromagnetic (EM) stress in reheating magnetogenesis scenarios. Both nonhelical and helical magneti…
Circular Polarization of Gravitational Waves from Early-Universe Helical Turbulence
Tina Kahniashvili, Axel Brandenburg, Grigol Gogoberidze +2
We perform direct numerical simulations to compute the net circular polarization of gravitational waves from helical (chiral) turbulent sources in the early Universe for a variety…
NANOGrav signal from MHD turbulence at QCD phase transition in the early universe
A. Neronov, A. Roper Pol, C. Caprini +1
The NANOGrav collaboration has recently reported evidence for the existence of a stochastic gravitational wave background in the 1-100 nHz frequency range. We argue that such backg…
Evolution of hydromagnetic turbulence from the electroweak phase transition
Axel Brandenburg, Tina Kahniashvili, Sayan Mandal +3
We present new simulations of decaying hydromagnetic turbulence for a relativistic equation of state relevant to the early universe. We compare helical and nonhelical cases either…
