Measuring gravitational-wave memory with LIGO and Pulsar Timing Arrays

Mergers of black holes cause permanent deformation of space, due to the Christodoulou effect. While this gravitational-wave memory signal is weak, I will argue it will be measurable once advanced LIGO reaches its design sensitivity. I will also show that Pulsar Timing Arrays will be sensitive to memory bursts from supermassive black hole mergers occuring billions of light years away
