Directed search for continuous gravitational-wave signals from the Galactic Center in the Advanced LIGO second observing run
Ornella J. Piccinni, P. Astone, S. D'Antonio +7
In this work we present the results of a search for continuous gravitational waves from the Galactic Center using LIGO O2 data. The search uses the Band-Sampled-Data directed searc…
Direct constraints on ultra-light boson mass from searches for continuous gravitational waves
Cristiano Palomba, Sabrina D'Antonio, Pia Astone +10
\textit{Superradiance} can trigger the formation of an ultra-light boson cloud around a spinning black hole. Once formed, the boson cloud is expected to emit a nearly periodic, lon…
How effective is machine learning to detect long transient gravitational waves from neutron stars in a real search?
Andrew L. Miller, Pia Astone, Sabrina D'Antonio +12
We present a comprehensive study of the effectiveness of Convolution Neural Networks (CNNs) to detect long duration transient gravitational-wave signals lasting fro…
A guide to LIGO-Virgo detector noise and extraction of transient gravitational-wave signals
The LIGO Scientific Collaboration, the Virgo Collaboration, B. P. Abbott +1135
The LIGO Scientific Collaboration and the Virgo Collaboration have cataloged eleven confidently detected gravitational-wave events during the first two observing runs of the advanc…
Search for gravitational waves from Scorpius X-1 in the second Advanced LIGO observing run with an improved hidden Markov model
The LIGO Scientific Collaboration, the Virgo Collaboration, B. P. Abbott +1134
We present results from a semicoherent search for continuous gravitational waves from the low-mass X-ray binary Scorpius X-1, using a hidden Markov model (HMM) to track spin wander…
Summary of Tests of General Relativity with the Binary Black Hole Signals from the LIGO-Virgo Catalog GWTC-1
Nathan K. Johnson-McDaniel
We summarize the four tests of general relativity carried out using the ten binary black hole signals detected by Advanced LIGO and Advanced Virgo and included in their first catal…
