Cosmic string gravitational wave backgrounds at LISA: II. Reconstruction of conventional signals over astrophysical foregrounds
Androniki Dimitriou, Daniel G. Figueroa, Peera Simakachorn +2
The paper investigates how well LISA can recover a stochastic gravitational‑wave background from cosmic strings when realistic astrophysical foregrounds are present, using the GWBa…
Cosmic string gravitational wave backgrounds at LISA: I. Signal survey, template reconstruction, and model comparison
Androniki Dimitriou, Daniel G. Figueroa, Peera Simakachorn +1
We present a catalog of gravitational wave background (GWB) signal templates from cosmic-string networks, based on relevant models proposed in the literature. We classify templates…
Reviving Motivated Inflationary Potentials with -inflation in the light of ACT
Milad Solbi, Daris Samart, Peera Simakachorn
Recent ACT data favor a higher scalar spectral index , placing models such as -attractor T-models and natural Inflation in tension with current observations. We propose a…
New Source for QCD Axion Dark Matter Production: Curvature Induced
Cem Eröncel, Yann Gouttenoire, Ryosuke Sato +2
We discuss a novel mechanism for generating dark matter from a fast-rolling scalar field, relevant for both inflation and rotating axion models, and apply it specifically to the (Q…
A universal bound on the duration of a kination era
Cem Eröncel, Yann Gouttenoire, Ryosuke Sato +2
We show that primordial adiabatic curvature fluctuations generate an instability of the scalar field sourcing a kination era. We demonstrate that the generated higher Fourier modes…
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…
