of these banks towards simulated populations of generic-spin systems. We then use these banks in a pipeline analysis of Gaussian noise to measure the increase in background incurred by using generic- instead of aligned-spin banks. Although the generic-spin banks have a factor of ten to twenty more templates than the aligned-spin banks, we nd an overall improvement in signal recovery at xed false-alarm rate for systems with high-mass ratio and highly precessing spins |up to 60% for neutron-star… 

Sensitivity of spin-aligned searches for neutron star-black hole systems using future detectors

Current searches for gravitational waves from compact-binary objects are primarily designed to detect the dominant gravitational-wave mode and assume that the binary components have spins which are

Search for intermediate mass black hole binaries in the first observing run of Advanced LIGO

During their first observational run, the two Advanced LIGO detectors attained an unprecedented sensitivity, resulting in the first direct detections of gravitational-wave signals produced by

Searching for the full symphony of black hole binary mergers

A new method for searching for compact binary mergers using waveforms that include higher-order mode effects, and a sensitivity increase of up to a factor of 2 in volume for high mass ratio, high total-mass systems is found.

Population Properties of Compact Objects from the Second LIGO–Virgo Gravitational-Wave Transient Catalog

We report on the population of 47 compact binary mergers detected with a false-alarm rate of < in the second LIGO–Virgo Gravitational-Wave Transient Catalog. We observe several characteristics of the

Detection and characterization of spin-orbit resonances in the advanced gravitational wave detectors era

Spin-orbit resonances have important astrophysical implications as the evolution and subsequent coalescence of supermassive black hole binaries in one of these configurations may lead to low recoil

Hierarchical search strategy for the efficient detection of gravitational waves from nonprecessing coalescing compact binaries with aligned-spins

This work presents here a two-stage hierarchical strategy to search for CBCs in data from a network of detectors and demonstrates the computational advantage in real life scenario by introducing it in the standard PyCBC pipeline with the usual restricted parameter space.

When will we observe binary black holes precessing?

After eleven gravitational-wave detections from compact-binary mergers, we are yet to observe the striking general-relativistic phenomenon of orbital precession. Measurements of precession would

Reducing the number of templates for aligned-spin compact binary coalescence gravitational wave searches using metric-agnostic template nudging

Efficient multi-dimensional template placement is crucial in computationally intensive matched-filtering searches for Gravitational Waves (GWs). Here, we implement the Neighboring Cell Algorithm

Use of gravitational waves to probe the formation channels of compact binaries

With the discovery of the binary black hole coalescences GW150914 and GW151226, the era of gravitational-wave astrophysics has started. Gravitational-wave signals emitted by compact binary

The Reliability of the Low-latency Estimation of Binary Neutron Star Chirp Mass

The LIGO and Virgo Collaborations currently conduct searches for gravitational waves from compact binary coalescences in real time. For promising candidate events, a sky map and distance estimation
