Abstract: "A space-based gravitational wave observatory targeting the milliHertz frequency band has the potential to inform many areas of physics and astrophysics including the nature of gravity in the strong-field limit, the formation and growth of massive black holes and their host galaxies, and the demographics of stellar compact objects. This strong science case has led to the Laser Interferometer Space Antenna (LISA) mission concept consistently receiving high rankings in major reviews in both the US and Europe. In 2016, the ESA-led LISA Pathfinder mission validated several key technologies for LISA and further strengthened the case for a timely implementation of LISA. In this talk, I will discuss the preliminary results from LISA Pathfinder and the outlook for a LISA-like mission in light of the successes of Pathfinder and LIGO."
