Laser Interferometer Space Antenna
Following the selection of The Gravitational Universe by ESA, and the successful flight of LISA Pathfinder, the LISA Consortium now proposes a 4 year mission in response to ESA's call for missions
TOPICAL REVIEW: Quasinormal modes of black holes and black branes
Quasinormal modes are eigenmodes of dissipative systems. Perturbations of classical gravitational backgrounds involving black holes or branes naturally lead to quasinormal modes. The analysis and
Gravitational-wave spectroscopy of massive black holes with the space interferometer LISA
Newly formed black holes are expected to emit characteristic radiation in the form of quasinormal modes, called ringdown waves, with discrete frequencies. LISA should be able to detect the ringdown
Inspiral, merger, and ringdown of unequal mass black hole binaries: A multipolar analysis
We study the inspiral, merger, and ringdown of unequal mass black hole binaries by analyzing a catalogue of numerical simulations for seven different values of the mass ratio (from q=M2/M1=1 to q=4).
Superradiance is a radiation enhancement process that involves dissipative systems. With a 60 year-old history, superradiance has played a prominent role in optics, quantum mechanics and especially
Geodesic stability, Lyapunov exponents, and quasinormal modes
Geodesic motion determines important features of spacetimes. Null unstable geodesics are closely related to the appearance of compact objects to external observers and have been associated with the
Testing the nature of dark compact objects: a status report
Very compact objects probe extreme gravitational fields and may be the key to understand outstanding puzzles in fundamental physics. These include the nature of dark matter, the fate of spacetime
Is the Gravitational-Wave Ringdown a Probe of the Event Horizon?
It is pointed out that this assumption that very compact objects with a light ring will display a similar ringdown stage, even when their quasinormal-mode spectrum is completely different from that of a black hole, is wrong.
Quasinormal Modes and Strong Cosmic Censorship.
A detailed description of linear scalar perturbations of such black holes, and conjecture that SCC is violated in the near extremal regime is given.
Quasinormal modes of Schwarzschild anti-de Sitter black holes: Electromagnetic and gravitational perturbations
We study the quasinormal modes (QNM) of electromagnetic and gravitational perturbations of a Schwarzschild black hole in an asymptotically anti\char21{}de Sitter (AdS) spacetime. Some of the
