When can gravitational-wave observations distinguish between black holes and neutron stars? [PDF]

open access: yes, 2013
Gravitational-wave observations of compact binaries have the potential to uncover the distribution of masses and angular momenta of black holes and neutron stars in the universe.

BLACK HOLE–NEUTRON STAR COALESCING BINARIES

open access: yesInternational Journal of Modern Physics D, 2010
Coalescing black hole–neutron star binaries have been invoked as possible progenitors of short gamma-ray bursts and are also among the most promising gravitational wave sources to be detected by ground-based laser interferometers. When the star is disrupted by tidal interactions before reaching the innermost stable circular orbit, the gravitational ...

Binary Black Hole Mergers in the First Advanced LIGO Observing Run

open access: yesPhysical Review X, 2016
The first observational run of the Advanced LIGO detectors, from September 12, 2015 to January 19, 2016, saw the first detections of gravitational waves from binary black hole mergers. In this paper, we present full results from a search for binary black

Physics-inspired deep learning to characterize the signal manifold of quasi-circular, spinning, non-precessing binary black hole mergers

open access: yesPhysics Letters B, 2020
The spin distribution of binary black hole mergers contains key information concerning the formation channels of these objects, and the astrophysical environments where they form, evolve and coalesce.

SDSSJ092712.65+294344.0: a candidate massive black hole binary [PDF]

open access: yes, 2009
In this Letter we explore the hypothesis that the quasar SDSSJ092712.65+294344.0 is hosting a massive black hole binary embedded in a circumbinary disc. The lightest, secondary black hole is active, and gas orbiting around it is responsible for the blue ...

Binary black hole spectroscopy [PDF]

open access: yesClassical and Quantum Gravity, 2007
We study parameter estimation with post-Newtonian (PN) gravitational waveforms for the quasi-circular, adiabatic inspiral of spinning binary compact objects. The performance of amplitude-corrected waveforms is compared with that of the more commonly used restricted waveforms, in Advanced LIGO and EGO.

Probing the presence of a single or binary black hole in the globular cluster NGC 6752 with pulsar dynamics

open access: yes, 2003
The five millisecond pulsars that inhabit NGC 6752 display locations or accelerations that are quite unusual compared to all other pulsars known in globular clusters. In particular PSR-A, a binary pulsar, lives in the cluster halo, while PSR-B and PSR-E,

Star Clusters with Primordial Binaries: III. Dynamical Interaction between Binaries and an Intermediate Mass Black Hole [PDF]

open access: yes, 2006
We present the first study of the dynamical evolution of an isolated star cluster that combines a significant population of primordial binaries with the presence of a central black hole.
