Description

The Laser Interferometer Space Antenna (LISA) is a planned space-based observatory to measure gravitational waves in the millihertz frequency band, expected to capture signals from millions of Galactic binaries and tens of merging massive black hole binaries. We introduce a novel, cost-effective global fit pipeline for extracting and characterizing these signals. The pipeline performs a time-evolving weekly analysis from 1 week to 1 year of observation. Additionally, we present a novel maximum likelihood algorithm for extracting multiple massive black hole binaries and demonstrate a signal extraction considering higher harmonic modes in a noisy data set.
