Biased Domain Wall Networks and their Gravitational Waves
Davide Barbini, Alessio Notari, Oriol Pujolàs +2
Cosmic Domain Wall networks are among the most interesting sources of a stochastic Gravitational Wave (GW) background from the early Universe. We present a thorough analysis of the…
Cuspidal Singularities in Collapsing Domain Walls
Jose J. Blanco-Pillado, Matthew Elley, Francesc Ferrer +4
Domain wall networks have attracted renewed interest, particularly in relation to the dynamics of network collapse. Accurately describing this process is challenging and typically…
Search for Peak Structures in the Stochastic Gravitational-Wave Background in LIGO-Virgo-KAGRA O1-O4a Datasets
Catalina-Ana Miritescu, Mario Martinez, Oriol Pujolas
We present a dedicated search for gravitational-wave backgrounds with nontrivial peak structures using data from the first three and the initial part of the fourth observing runs o…
From Cusps to Swallowtails: Domain Wall singularities in 2+1 dimensions
Jose J. Blanco-Pillado, Daniel Jiménez-Aguilar, Oriol Pujolà s
The effective Nambu-Goto description of -dimensional domain walls predicts singular behavior of its worldsheet resulting in swallowtail bifurcations. This phenomenon is inti…
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…
Soft Oscillons
Fabio van Dissel, Oriol Pujolà s
We present a novel type of soliton dubbed soft oscillons. In contrast with conventional oscillons the soft counterparts come in a continuum of unboundedly large sizes. They are pec…
