Cosmological scaling of precursor domain walls
Mainak Mukhopadhyay, Oriol Pujolas, George Zahariade
Domain wall (DW) networks have a large impact on cosmology and present interesting dynamics that can be controlled by various scaling regimes. In the first stage after spontaneous…
Primordial gravitational wave backgrounds from phase transitions with next generation ground based detectors
Chiara Caprini, Oriol Pujolàs, Hippolyte Quelquejay-Leclere +2
Third generation ground-based gravitational wave (GW) detectors, such as Einstein Telescope and Cosmic Explorer, will operate in the Hz frequency band, with a b…
Constraints on primordial black holes from LIGO-Virgo-KAGRA O3 events
M. Andrés-Carcasona, A. J. Iovino, V. Vaskonen +4
Primordial black holes (PBH) can efficiently form black hole binaries in the early universe. We update the resulting constraints on PBH abundance using data from the third observat…
Collapsing Domain Wall Networks: Impact on Pulsar Timing Arrays and Primordial Black Holes
Ricardo Z. Ferreira, Alessio Notari, Oriol Pujolàs +1
Unstable domain wall (DW) networks in the early universe are cosmologically viable and can emit a large amount of gravitational waves (GW) before annihilating. As such, they provid…
