Electromagnetic counterparts of LISA massive black hole mergers: the next challenge. Abstract: Multi-messenger astronomy which combines low-frequency gravitational wave observations of massive black hole coalescences with contemporary observations in the electromagnetic domain enables unique tests in astrophysics and cosmology. The possibility of performing these tests depends on both LISA’s capability to well localise these sources in their pathway to coalescence, and for the new generation of telescopes to slew as fast as possible and scan deeply the corresponding galactic fields. By using the detailed information contained in a mock universe, we explore the habitat of the merging systems, the properties of their host galaxy and the detectability of an emerging X-ray activity.
