Talk Title: Mapping the Gravitational Wave Background 

Abstract: In this talk, I will discuss detecting the gravitational wave background and its anisotropies both with ground- and space- based detectors. I will review the work we have done with the LIGO detectors and show the upper limits we obtain from LIGO O1 and O2 data sets. I will then analyse the ability of the LISA detector to reconstruct a stochastic, incoherent gravitational wave signal on the sky, illustrating the response of the detector as a function of both time and frequency. Finally, I will show preliminary results of map injection+reconstruction obtained within our ongoing project as a part of the LISA Cosmology Working Group.
