393. The dawn of gravitational-wave physics and astronomy

Gravitational wave observations from merging black hole binaries can be used to constrain astrophysical models and test general relativity in dynamical spacetimes. In my talk I will highlight some of the astrophysical implications and bounds on deviations from GR deduced from LIGO's 3.9 detections so far.

394. Gravitational-wave displacement and spin memory effects

David Nichols

The gravitational-wave displacement and spin memory effects are predictions of general relativity that can be caused by nonlinearities in Einstein's equations. They are characterized by constant changes in the strain and in the time integral of the strain's magnetic-parity part, respectively, before and after the passage of a burst of gravitational waves. Observing these effects...

395. Detection of Gravitational Wave transients with minimal assumptions and signal error waveform

Matteo Di Giovanni

Searches for transient gravitational waves are performed either by exploiting detailed knowledge of the waveform - template based searches - or by making minimal assumptions about the signal morphology - generic burst searches. The latter are sensitive to gravitational waves emitted by a wider range of sources including compact binary coalescences and isolated compact objects. This...

We propose that stellar-mass binary black holes like GW150914 will become a tool to explore the local Universe within ~100Mpc in the era of the Laser Interferometer Space Antenna (LISA). High calibration accuracy and annual motion of LISA could enable us to localize up to ~60 binaries more accurately than the error volume of ~100Mpc^3 without electromagnetic counterparts under...

398. The Astrophysics of the Gravitational Wave Detections

Cole Miller

6/21/17, 11:55 AM

The LIGO-Virgo detections of three double black hole coalescences, plus a third likely BH-BH merger, have begun to give us a glimpse of the astrophysics of thes e events. There are currently two broad categories of models for coalescing compact binaries: evolution of an isolated massive binary and dynamical processes in dense stellar systems. I will discuss some of the specifics...
