All-sky search for periodic gravitational waves in the O1 LIGO data
Abbott, B. P.; Abbott, R.; Abbott, T. D.; Acernese, F.; Ackley, K.; e.a. (American Physical Society, 2017-09)We report on an all-sky search for periodic gravitational waves in the frequency band 20–475 Hz and with a frequency time derivative in the range of [-1.0,+0.1]×10[superscript -8] Hz/s. Such a signal could be produced by ... -

Constraints on cosmic strings using data from the first Advanced LIGO observing run
Abbott, B. P.; Abbott, R.; Abbott, T. D.; Acernese, F.; Ackley, K.; e.a. (American Physical Society, 2018-05)Cosmic strings are topological defects which can be formed in grand unified theory scale phase transitions in the early universe. They are also predicted to form in the context of string theory. The main mechanism for a ... -

First narrow-band search for continuous gravitational waves from known pulsars in advanced detector data
Abbott, B. P.; Abbott, R.; Abbott, T. D.; Acernese, F.; Ackley, K.; e.a. (American Physical Society, 2017-12)Spinning neutron stars asymmetric with respect to their rotation axis are potential sources of continuous gravitational waves for ground-based interferometric detectors. In the case of known pulsars a fully coherent search, ... -
First Search for Nontensorial Gravitational Waves from Known Pulsars
Abbott, B. P.; Abbott, R.; Abbott, T. D.; Acernese, F.; Ackley, K.; e.a. (American Physical Society, 2018-01)We present results from the first directed search for nontensorial gravitational waves. While general relativity allows for tensorial (plus and cross) modes only, a generic metric theory may, in principle, predict waves ... -
Full band all-sky search for periodic gravitational waves in the O1 LIGO data
