A Lunar Seismic and Gravitational Antenna (LSGA)

We propose a thesis for the study of the scientific potential and technical feasibility of a Lunar Seismic and Gravitational Antenna (LSGA). LSGA is a response to the call of ideas of ESA for a Lunar Lander. It concerns the deployment of an engineered fiber distributed acoustic sensor system (EFDAS) on the lunar surface, in complementarity and projected increase of sensitivity, to the Very Broad Band VBBZ Farside Seismic Suite (VBBZ-FSS).

Disentangling astrophysical populations of GW signals and characterizing their properties with LISA

LISA is a space-based gravitational wave (GW) observatory which is planned for launch in 2034. It consists of three satellites in the free fall in the heliocentric orbit forming an equilateral triangle. Satellites exchange the laser light forming transponding interferometry allowing to detect GWs in the mHz band.  A plethora of gravitational-wave signals from different astrophysical sources is expected to be observed by LISA. These sources include galactic white dwarf binaries, extreme mass-ratio inspirals, massive black hole binaries, etc.

The advanced Virgo + project: improving the sensitivity of the gravitational-wave detector Virgo

Second generation gravitational wave (GW) detectors opened the era of gravitational wave astronomy with the fist GW detection in 2015 and are now approaching their design sensitivity. During the 3 past observation runs, they detected 15 GW signals produced by the merging of binary compact objects, providing a wealth of scientific results ranging from the general relativity, to astrophysics and cosmology.

Stage A lunar sensor network for gravitational was and geoscientific studies

This stage, will be concentrated on the scientific potential and the technical possibilities of a distributed network on the lunar surface, in order to a) detect Gravitational Waves (GW) b) perform a detailed seismological study of the moon, including the precise determination of its inner structure, c) eventually detect acoustically High Energy Cosmic rays impacting on the moon surface.
