Ultrahigh frequency primordial gravitational waves beyond the kHz: The case of cosmic strings

Autor: Servant, Géraldine, Simakachorn, Peera

Publikováno v: Phys. Rev. D 109, 103538 (2024)

We investigate gravitational-wave backgrounds (GWBs) of primordial origin that would manifest only at ultra-high frequencies, from kilohertz to 100 gigahertz, and leave no signal at either LIGO, Einstein Telescope, Cosmic Explorer, LISA, or pulsar-ti

Cosmological Background Interpretation of Pulsar Timing Array Data

Autor: Figueroa, Daniel G., Pieroni, Mauro, Ricciardone, Angelo, Simakachorn, Peera

Publikováno v: Phys. Rev. Lett. 132, 171002 (2024)

We discuss the interpretation of the detected signal by Pulsar Timing Array (PTA) observations as a gravitational wave background (GWB) of cosmological origin. We combine NANOGrav 15-years and EPTA-DR2new data sets and confront them against backgroun

Revealing the Primordial Irreducible Inflationary Gravitational-Wave Background with a Spinning Peccei-Quinn Axion

Autor: Gouttenoire, Yann, Servant, Géraldine, Simakachorn, Peera

The primordial irreducible gravitational-wave background due to quantum vacuum tensor fluctuations produced during inflation spans a large range of frequencies with an almost scale-invariant spectrum but is too low to be detected by the next generati
