Gravitational waves from plunges into Gargantua

Geoffrey Compère, Kwinten Fransen, Thomas Hertog +1

We analytically compute time domain gravitational waveforms produced in the final stages of extreme mass ratio inspirals of non-spinning compact objects into supermassive nearly ex…

Constraints on cosmic strings using data from the first Advanced LIGO observing run

The LIGO Scientific Collaboration, the Virgo Collaboration, B. P. Abbott +1042

Cosmic strings are topological defects which can be formed in GUT-scale phase transitions in the early universe. They are also predicted to form in the context of string theory. Th…

First narrow-band search for continuous gravitational waves from known pulsars in advanced detector data

The LIGO Scientific Collaboration, the Virgo Collaboration, B. P. Abbott +1096

Spinning neutron stars asymmetric with respect to their rotation axis are potential sources of continuous gravitational waves for ground-based interferometric detectors. In the cas…

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

The LIGO Scientific Collaboration, the Virgo Collaboration, B. P. Abbott +957

The first observing run of Advanced LIGO spanned 4 months, from September 12, 2015 to January 19, 2016, during which gravitational waves were directly detected from two binary blac…

First search for nontensorial gravitational waves from known pulsars

The LIGO Scientific Collaboration, the Virgo Collaboration, B. P. Abbott +1050

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…
