Gravitational wave sources for pulsar timing arrays

Physical Review D, 2023
Very recently, several pulsar timing array collaborations, including CPTA, EPTA, and NANOGrav, reported their results from searches for an isotropic stochastic gravitational wave background (SGWB), with each finding positive evidence for SGWB.

Prospects for observing and localizing gravitational-wave transients with Advanced LIGO, Advanced Virgo and KAGRA

Living Reviews in Relativity, 2018
We present possible observing scenarios for the Advanced LIGO, Advanced Virgo and KAGRA gravitational-wave detectors over the next decade, with the intention of providing information to the astronomy community to facilitate planning for multi-messenger ...

Astrometric Search Method for Individually Resolvable Gravitational Wave Sources with Gaia [PDF]

Physical Review Letters, 2017
Gravitational waves (GWs) cause the apparent position of distant stars to oscillate with a characteristic pattern on the sky. Astrometric measurements (e.g., those made by Gaia) provide a new way to search for GWs.

Sources of gravitational waves

AIP Conference Proceedings, 2001
We discuss the characteristic features of the signals emitted by some astrophysical sources of gravitational waves, that are most likely to be seen by gravitational detectors in the near future.

Challenges and opportunities of gravitational-wave searches above 10 kHz

Living Reviews in Relativity
The first direct measurement of gravitational waves by the LIGO and Virgo collaborations has opened up new avenues to explore our Universe. This White Paper outlines the challenges and gains expected in gravitational-wave searches at frequencies above ...

Astrophysical Sources of Gravitational Waves

Nuclear Physics B - Proceedings Supplements, 2000
The interferometric detectors of gravitational waves (GW) (such as VIRGO and LIGO) will search for events in a frequency band within a few Hz and a few kHz, where several sources are expected to emit. In this talk we outline briefly the current theoretical knowledge on the emission of GW in events such as the coalescence of compact binaries, the ...

Compact Sources of Gravitational Waves

2020
In this chapter, we describe how compact cosmic objects like white dwarfs, neutron stars and black holes are formed. Stars for much of their life produce energy, through nuclear fusion, which is emitted from their surface. In this stage, stars have a fixed size which is maintained by balancing their own gravitational field with the high pressure of ...

Gravitational wave astronomy with TianQin

Reports on progress in physics. Physical Society
The opening of the gravitational wave window has significantly enhanced our capacity to explore the Universe’s most extreme and dynamic sector. In the mHz frequency range, a diverse range of compact objects, from the most massive black holes at the ...

Probing the sources of gravitational waves

2020
Since almost 60 years, physicists have been puzzled about the origin of ultra-high-energy (UHE) cosmic rays (CRs). In 2015, the first direct measurement of gravitational waves (GWs) shed light on a new promising type of source candidate: the merging processes of compact binary systems (compact binary mergers, CBMs).
