Denoising of gravitational wave signals via dictionary learning algorithms
Alejandro Torres-Forné, Antonio Marquina, José A. Font +1
Gravitational wave astronomy has become a reality after the historical detections accomplished during the first observing run of the two advanced LIGO detectors. In the following y…
Dynamical formation of a hairy black hole in a cavity from the decay of unstable solitons
Nicolas Sanchis-Gual, Juan Carlos Degollado, José A. Font +2
Recent numerical relativity simulations within the Einstein--Maxwell--(charged-)Klein-Gordon (EMcKG) system have shown that the non-linear evolution of a superradiantly unstable Re…
Rotational properties of hypermassive neutron stars from binary mergers
Matthias Hanauske, Kentaro Takami, Luke Bovard +4
Determining the differential-rotation law of compact stellar objects produced in binary neutron stars mergers or core-collapse supernovae is an old problem in relativistic astrophy…
Classification methods for noise transients in advanced gravitational-wave detectors II: performance tests on Advanced LIGO data
Jade Powell, Alejandro Torres-Forné, Ryan Lynch +5
The data taken by the advanced LIGO and Virgo gravitational-wave detectors contains short duration noise transients that limit the significance of astrophysical detections and redu…
Dynamical formation of a Reissner-Nordström black hole with scalar hair in a cavity
Nicolas Sanchis-Gual, Juan Carlos Degollado, Carlos Herdeiro +2
In a recent letter, we presented numerical relativity simulations, solving the full Einstein--Maxwell--Klein-Gordon equations, of superradiantly unstable Reissner-Nordström black h…
On the dynamics of tilted black hole-torus systems
Vassilios Mewes, Filippo Galeazzi, José A. Font +2
We present results from three-dimensional, numerical relativity simulations of a {\it tilted} black hole-thick accretion disc system. The simulations are analysed using tracer part…
