Description

The LISA observation band is expected to be populated with various
gravitational wave signals overlapping in time and frequency, making the
individual treatment for each source impossible.
We present a global-fit pipeline to disentangle the merging massive
black hole binaries (MBHB) and the inspiralling Galactic white dwarf
binaries (GBs) present in the simulate one-year-long LISA data.
The pipeline consists of a kick-in step of speedy approximative MBHB
signal reconstruction and an iterative Bayesian detection and parameter
estimation step for GBs, MBHBs as well as inference of the noise model.
