Asymptotics and Universality in Black Holes: from the quasinormal Weyl’s law to the binary merger waveform

J.L Jaramillo, L. Al Sheikh, J. Besson, B. Krishnan et autres

Abstract Current state-of-the-art approaches to black hole (BH) dynamics, encompassing several effective approximation schemes, offer a remarkable control of the quantitative aspects of strong gravity. They also provide key insights into some qualitative aspects of the problem. In spite of this, there …

Full Band All-sky Search for Periodic Gravitational Waves in the O1 LIGO Data

T K ND TPC collaboration, T. D. Abbott, R (15485435) Abbott, T. D. Abbott et autres

We report on a new all-sky search for periodic gravitational waves in the frequency band 475-2000 Hz and with a frequency time derivative in the range of [-1.0,+0.1]×10-8 Hz/s. Potential signals could be produced by a nearby spinning and slightly nonaxisymmetric isolated …

GW170817: Implications for the Stochastic Gravitational-Wave Background from Compact Binary Coalescences

T K ND TPC collaboration, T. D. Abbott, R (15485435) Abbott, T. D. Abbott et autres

The LIGO Scientific and Virgo Collaborations have announced the first detection of gravitational waves from the coalescence of two neutron stars. The merger rate of binary neutron stars estimated from this event suggests that distant, unresolvable binary neutron stars create a significant …

Effects of Data Quality Vetoes on a Search for Compact Binary Coalescences in Advanced LIGO's First Observing Run

T K ND TPC collaboration, T. D. Abbott, R (15485435) Abbott, T. D. Abbott et autres

The first observing run of Advanced LIGO spanned 4 months, from 12 September 2015 to 19 January 2016, during which gravitational waves were directly detected from two binary black hole systems, namely GW150914 and GW151226. Confident detection of gravitational waves requires an …

GW170104: Observation of a 50-Solar-Mass Binary Black Hole Coalescence at Redshift 0.2

T K ND TPC collaboration, T. D. Abbott, R (15485435) Abbott, T. D. Abbott et autres

We describe the observation of GW170104, a gravitational-wave signal produced by the coalescence of a pair of stellar-mass black holes. The signal was measured on January 4, 2017 at 10∶11:58.6 UTC by the twin advanced detectors of the Laser Interferometer Gravitational-Wave Observatory …

First low-frequency Einstein@Home all-sky search for continuous gravitational waves in Advanced LIGO data

T K ND TPC collaboration, T. D. Abbott, R. Abbott, T. D. Abbott et autres

We report results of a deep all-sky search for periodic gravitational waves from isolated neutron stars in data from the first Advanced LIGO observing run. This search investigates the low frequency range of Advanced LIGO data, between 20 and 100 Hz, much …

Search for gravitational waves from Scorpius X-1 in the first Advanced LIGO observing run with a hidden Markov model

T K ND TPC collaboration, T. D. Abbott, R. Abbott, T. D. Abbott et autres

Results are presented from a semicoherent search for continuous gravitational waves from the brightest low-mass X-ray binary, Scorpius X-1, using data collected during the first Advanced LIGO observing run. The search combines a frequency domain matched filter (Bessel-weighted F-statistic) with a hidden …

Search for gravitational waves from binary black hole inspiral, merger and ringdown

The LIGO Scientific Collaboration, J. Abadie, B. P. Abbott, R. Abbott et autres

We present the first modeled search for gravitational waves using the complete binary black-hole gravitational waveform from inspiral through the merger and ringdown for binaries with negligible component spin. We searched approximately 2 years of LIGO data, taken between November 2005 and …
