Description

Gravitational wave signals from ultra-short period double white dwarf binaries detectable by LISA are unique Galactic stellar tracers. I will show that as an all-sky survey that does not suffer from contamination and dust extinction LISA will map the Milky Way and environs. In particular, the density distribution of DWDs detected by LISA can be used to constrain scale parameters of the Milky Way's bulge, disc and central bar. Finally, I will show that LISA can detect known classical dwarf satellites and potentially discover new ones.
