Virtual ASD Colloquium
|LISA and the Gravitational Wave Universe
Monica Colpi (University of Milano Bicocca)
The Laser Interferometer Space Antenna (LISA) - a gigameter scale space-based gravitational wave observatory - will explore the gravitational wave universe in the band from below 0.1 mHz to above 0.1 Hz. LISA will grant us access to a huge cosmological volume with unprecedented reach deep into space, detecting signals up to redshifts 20-30 and even beyond if sources exist. LISA will detect massive black hole coalescences to unveil the yet unknown origins of the first quasars and to shed light into the teeming population of middleweight black holes forming in galactic dark matter halos. LISA will discover the link between the most energetic phenomena in the universe - accreting and merging black holes - and the grand design of galaxy assembly. I will then address how the X-ray mission Athena joining LISA in concurrent multi-messenger observations of massive black hole coalescences will enhance immensely our knowledge of gas accreting in the violently changing spacetime of a merger.
