The dawn of gravitational wave astronomy at light-year wavelengths: insights from pulsar timing arrays

Sign Up to like & get
recommendations! Published in 2025 at "Astrophysics and Space Science"

DOI: 10.1007/s10509-025-04513-9

Abstract: Arrays of precisely-timed millisecond pulsars are used to search for gravitational waves with periods of months to decades. Gravitational waves affect the path of radio pulses propagating from a pulsar to Earth, causing the arrival… read more here.

DOI: 10.1016/j.actaastro.2017.11.014

Abstract: Abstract This paper develops a timing solution for the X-ray pulsar timing model without the use of the initial radio model parameters. First, we address the problem of phase ambiguities for the pre-fit residuals in… read more here.

DOI: 10.1088/1361-6382/adbbab

Abstract: As pulsar timing arrays (PTAs) transition into the detection era of the stochastic gravitational wave background (GWB), it is important for PTA collaborations to review and possibly revise their observing campaigns. The detection of a… read more here.

DOI: 10.1088/1361-6382/ae19c2

Abstract: This review summarises recent progress in pulsar timing array research and the current status of nanohertz gravitational wave astronomy. I outline the techniques enabling decade-long, sub-microsecond-precision timing, present results from PTA collaborations between 2023–2025, and… read more here.

DOI: 10.1088/1475-7516/2019/03/032

Abstract: We study how to probe bispectra of stochastic gravitational waves with pulsar timing arrays. The bispectrum is a key to probe the origin of stochastic gravitational waves. In particular, the shape of the bispectrum carries… read more here.

DOI: 10.1088/1475-7516/2024/12/045

Abstract: We perform an observational study of modified gravity considering a potential inflationary interpretation of pulsar timing arrays (PTA). We use a motivated model known as no slip in which the gravitational wave propagation is modified.… read more here.

recommendations! Published in 2024 at "Chinese Physics B"

DOI: 10.1088/1674-1056/ad9a98

Abstract: Recent observations by pulsar timing array collaborations have detected a stochastic common-spectrum signal, which may originate from scalar-induced gravitational waves generated by primordial curvature perturbations during inflation. Using the NANOGrav 15-year data set, we explore… read more here.
