Annual report dates come from the budget period on your award notice. That date is not public, so it is not shown here.

How we got this date

NSF lists this award's end date as 31 July 2028.
NSF rules say the final report is due no later than 120 days after that.
So the final report is due by 28 November 2028.

Abstract

In 2015, the LIGO detectors, funded by NSF, made the first direct detection of gravitational waves (GWs): ripples in spacetime resulting from the collision of two distant black holes. Since then, LIGO has observed GWs from almost 400 black-hole collisions and two binary neutron star collisions, allowing scientists to learn about these objects and about gravity itself. The primary scientific objective of this award…
