Gravitational-wave polarizations: what have we learned, what will we learn, and why does it matter
Maximiliano Isi, LIGO, Caltech

Polarizations are a fundamental property of the geometry of gravitational
waves (GWs), determining the directions in which space is stretched and
squeezed as the waves whiz by. With the detection of GW170814, we have
obtained some first direct evidence that GW polarizations are as Einstein
predicted---but there is much more to be learned with future measurements.
In this talk, I will review the basics of GW polarizations, summarize the
implications of recent compact-binary detections, and outline future ways to
study this basic property of gravity with ground-based detectors.
