Lunar Science and Exploration activities in the framework of the Lunar Gravitation-Wave Antenna (LGWA) collaboration

he Lunar Gravitational-wave Antenna (LGWA) is a mission conceived as an array of stations to measure the vibrations of the Moon caused by gravitational waves (GWs). LGWA will lead to the first observation of GW signals in the decihertz band greatly expanding our understanding of the universe and laying out a path to eventually probe the moment of its creation. The collaboration is working to build-up the science and technology underlying a successful mission. The final objective is to deploy an array of high-end cryogenic seismometers in one of the Permanently shadowed regions (PSRs) of the Moon. The LGWA seismic stations will also be unique contributions to a lunar geophysical network shedding light on the history of lunar formation. 

In this framework, Working Group 2 (Lunar Science and Exploration) is integrating researchers with different background as seismology, geophysics, planetology and astrophysics to build-up the collaborative group whose ambitious targets are: to define the landing site, its geology and its site response, to model the expected background noise and the noise correlation and to predict the lunar response to GWs. Ongoing activities include synthetic modelling of the lunar regolith and the study of the surface geology.
