On a time scale of years to decades, gravitational wave (GW) astronomy will become a reality. Low frequency (∼10 −9 Hz) GWs are detectable through long-term timing observations of the most stable…
Low-frequency gravitational-wave science with eLISA/NGO

We review the expected science performance of the New Gravitational-Wave Observatory (NGO, a.k.a. eLISA), a mission under study by the European Space Agency for launch in the early 2020s. eLISA will…
European Pulsar Timing Array Limits On An Isotropic Stochastic Gravitational-Wave Background
- L. Lentati, S. Taylor, J. Verbiest

- 14 April 2015
We present new limits on an isotropic stochastic gravitational-wave background (GWB) using a six pulsar dataset spanning 18 yr of observations from the 2015 European Pulsar Timing Array data release.…
Science with the space-based interferometer eLISA: Supermassive black hole binaries
- A. Klein, E. Barausse, B. Wardell

- 17 November 2015
We compare the science capabilities of different eLISA mission designs, including four-link (two-arm) and six-link (three-arm) configurations with different arm lengths, low-frequency noise…
Interaction of Massive Black Hole Binaries with Their Stellar Environment. I. Ejection of Hypervelocity Stars
We use full three-body scattering experiments to study the ejection of hypervelocity stars (HVSs) by massive black hole binaries (MBHBs) at the centers of galaxies. Ambient stars drawn from a…
Systematic investigation of the expected gravitational wave signal from supermassive black hole binaries in the pulsar timing band

In this letter we carry out the first systematic investigatio n of the expected gravitational wave (GW) background generated by supermassive black hole (SMBH) binaries in the nHz frequency band…
Limiting eccentricity of subparsec massive black hole binaries surrounded by self-gravitating gas discs
We study the dynamics of supermassive black hole binaries embedded in circumbinary gaseous discs, with the SPH code GADGET-2. The sub-parsec binary (of total mass M and mass ratio q = 1/3) has…
The International Pulsar Timing Array: First Data Release
