On the complementarity of pulsar timing and space laser interferometry for supermassive black hole binaries individual detection
complementarity pulsar timing space laser interferometry supermassive black hole
2011/10/14
For the observation of an individual supermassive black hole binary (SMBHB), the complementarity between pulsar timing (PT) and space laser interferometry (SLI) has been previously suggested. Herein s...
Long-term evolution of massive black hole binaries. IV. Mergers of galaxies with collisionally relaxed nuclei
large-scale structure of Universe – cosmology: theory – cosmology: observations – cosmological parameters
2011/10/12
We simulate mergers between galaxies containing collisionally-relaxed nuclei around massive black holes (MBHs). Our galaxies contain four mass groups, representative of old stellar populations; a prim...
Electromagnetic counterparts of supermassive black hole binaries resolved by pulsar timing arrays
black hole physics — gravitational waves — accretion, accretion discs— galaxies: active
2011/10/9
Pulsar timing arrays (PTAs) are expected to detect gravitational waves (GWs) from individual low-redshift (z<1.5) compact supermassive (M>10^9 Msun) black hole (SMBH) binaries with orbital periods of ...
Multimessenger astronomy with pulsar timing and X-ray observations of massive black hole binaries
Black hole physics – Accretion, accretion discs – Gravitational waves –pulsars: general – X-rays: general
2011/10/9
We demonstrate that very massive (>10^8\msun), cosmologically nearby (z<1) black hole binaries (MBHBs), which are primary targets for ongoing and upcoming pulsar timing arrays (PTAs), are particularly...
Extending the effective-one-body Hamiltonian of black-hole binaries to include next-to-next-to-leading spin-orbit couplings
Extending Hamiltonian black-hole binaries couplings
2011/10/17
In the effective-one-body (EOB) approach the dynamics of two compact objects of masses m1 and m2 and spins S1 and S2 is mapped into the dynamics of one test particle of mass mu = m1 m2/(m1+m2) and spi...

We conduct a descriptive analysis of the multipolar structure of gravitational-radiation waveforms from equal-mass aligned-spin mergers, following an approach first presented in the complementary cont...

2010/11/12
Context. We present angle-dependent, broad-band intensity spectra from accretion disks around black holes of 10 M⊙. In our computations disks are assumed to be slim, which means that the radial advect...
Intermediate Mass Ratio Black Hole Binaries: Numerical Relativity meets Perturbation Theory
black-hole binaries proof-of-concept
2010/3/17
We study black-hole binaries in the intermediate-mass-ratio regime 0.01 < q < 0.1 with a new technique that makes use of nonlinear numerical trajectories and efficient perturbative evolutions to compu...

2010/3/18
Coalescing massive Black Hole binaries are the strongest and probably the most important gravitational wave sources in the LISA band. The spin and orbital precessions bring complexity in the waveform ...

2010/3/18
We review some of the recent dramatic developments in the fully nonlinear simulation of generic, highly-precessing, black-hole binaries, and introduce a new approach for generating hybrid post-Newtoni...
