@article{Banagiri2021MappingTG, title={Mapping the gravitational-wave sky with LISA: a Bayesian spherical harmonic approach}, author={Sharan Banagiri and Alex Criswell and Tommy Kuan and Vuk Mandic and Joseph D. Romano and Stephen R. Taylor}, journal={Monthly Notices of the Royal Astronomical Society}, year={2021} }

The millihertz gravitational-wave frequency band is expected to contain a rich symphony of signals with sources ranging from Galactic white dwarf binaries to extreme mass ratio inspirals. Many of these gravitational-wave signals will not be individually resolvable. Instead, they will incoherently add to produce stochastic gravitational-wave confusion noise whose frequency content will be governed by the dynamics of the sources. The angular structure of the power of the confusion noise will be…
