We present the results of a search for long-duration gravitational-wave transients in the data from the Advanced LIGO second observation run; we search for gravitational-wave transients of 2--500 s duration in the 24--2048 Hz frequency band with minimal assumptions about signal properties …

We present the first Advanced LIGO and Advanced Virgo search for ultracompact binary systems with component masses between $0.2\text{ }\text{ }{M}_{\ensuremath{\bigodot}}--1.0\text{ }\text{ }{M}_{\ensuremath{\bigodot}}$ using data taken between September 12, 2015 and January 19, 2016. We find no viable gravitational wave candidates. Our …

We analyze the impact of a proposed tidal instability coupling $p$-modes and $g$-modes within neutron stars on GW170817. This non-resonant instability transfers energy from the orbit of the binary to internal modes of the stars, accelerating the gravitational-wave driven inspiral. We model …

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 $[\ensuremath{-}1.0,+0.1]\ifmmode\times\else\texttimes\fi{}1{0}^{\ensuremath{-}8}\text{ }\mathrm{Hz}/\mathrm{s}$. Potential signals could be produced by a nearby spinning and slightly nonaxisymmetric isolated …

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 network of Nambu-Goto cosmic strings …

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 …

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 with up to six different polarizations. This analysis is sensitive …

The Advanced LIGO observatories detected gravitational waves from two binary black hole mergers during their first observation run (O1). We present a high-energy neutrino follow-up search for the second gravitational wave event, GW151226, as well as for gravitational wave candidate LVT151012. We …

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 stellar-mass binary black hole systems. This paper reports on an all-sky search for gravitational waves (GWs) from …

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 $\mathcal{F}$-statistic) with a hidden …

In Advanced LIGO, detection and astrophysical source parameter estimation of the binary black hole merger GW150914 requires a calibrated estimate of the gravitational-wave strain sensed by the detectors. Producing an estimate from each detector's differential arm length control loop readout signals requires …

We report here the non-detection of gravitational waves from the merger of binary neutron star systems and neutron-star--black-hole systems during the first observing run of Advanced LIGO. In particular we searched for gravitational wave signals from binary neutron star systems with component …
