        "The Present and Future of Pulsar Timing Array Experiments"

Kivonatos ismertetés:
In the wake of the recent first detections of kilohertz gravitational waves 
(GWs) by the ground-based experiment LIGO, pulsar timing array (PTA) 
experiments are eager to open the next window onto the GW universe in the 
much lower nanohertz regime. In this talk, I will describe the present state 
of PTA science, focusing on recent results from the North American Nanohertz 
Observatory for Gravitational Waves (NANOGrav). I will also speculate on the 
long-term prospects of continuing to produce astrophysically interesting 
science, since PTA experiments require decade-long timescales to operate. In 
an important contrast to other GW experiments, I will make the argument that 
the ancillary science from PTA experiments is commensurate to their primary 
goals, and justifies continued investment in pushing this frontier of GW 
astrophysics.
