GW SIG Seminar: Deci-hertz Interferometer Space Antenna (DISA)

A virtual GW SIG seminar will be held 17 June 2026 at 1:00pm ET. The event is part of the Community GW SIG and is listed as a seminar. The presentation will be given by Jacob Slutsky, NASA / GSFC.

Slutsky will explain why measuring deci-Hertz (dHz) gravitational-wave emission is essential to answer the origins and fate of massive compact objects such as black holes, neutron stars, and white dwarfs.

He outlines the highest-priority science goals motivating a dHz observatory, the minimum sensitivity required to make these observations, and the fastest, least-costly mission that meets those requirements. "Like COBE rather than Plank, we optimize time to first knowledge over ultimate sensitivity," he says, and dubs the concept the Deci-hertz Interferometer Space Antenna (DISA).
