Continuous gravitational waves from Galactic neutron stars: demography, detectability and prospects

Abstract: We study the prospects for detection of continuous gravitational signals from "normal" Galactic neutron stars. We use a synthetic population generated by evolving stellar remnants in time, according to several models. We also briefly treat the case of recycled neutron stars. We consider the most recent constraints set by all-sky searches for continuous gravitational waves and use them for our detectability criteria. We discuss detection prospects for the current and the next generation of gravitational wave de… Show more

“…Depending on the assumptions, the nearest unknown neutron star could be as close as ≈10 pc (Dergachev & Papa 2020;Pagliaro et al 2023), where this search probes the interesting region of ellipticities between 10 −7 and 10 −9 for sufficiently Overall, ellipticities at the level of 10 −6 are usually considered reasonable, and the reach of this search for objects with this deformation and rotating faster than 150 Hz is 1 kpc.…”

“…´--, carried out on the distributed computing volunteer project Einstein@Home and the ATLAS supercomputer at the Max Planck Institute (MPI) for Gravitational Physics in Hannover. The frequency-spin-down range is based on the predictions of Pagliaro et al (2023), according to which more than 95% of the potentially detectable sources lie in this range.…”

“…With the model for the spin and magnetic field evolution of neutron stars described above, we now consider the effect of such a model on several neutron star properties and observables through a series of simulations. For each of our simulations, we draw the initial spin-period P 0 and initial magnetic field B p,0 from astrophysically motivated distributions p (Igoshev et al 2022;Pagliaro et al 2023)…”
