Astrodynamical middle-frequency interferometric gravitational wave observatory AMIGO: Mission concept and orbit design

Understand

AMIGO is a first-generation Astrodynamical Middle-frequency Interferometric GW Observatory.

• The scientific goals of AMIGO are: to bridge the spectra gap between first-generation high-frequency and low-frequency GW sensitivities; to detect intermediate mass BH coalescence; to detect inspiral phase and predict time of binary black hole coalescence together with neutron star coalescence for ground interferometers; to detect compact binary inspirals for studying stellar evolution and galactic population.
• The mission concept is to use time delay interferometry for a nearly triangular formation of 3 drag-free spacecraft with nominal arm length 10,000 km, emitting laser power 2-10 W and telescope diameter 300-500 mm.
• The design GW sensitivity in the middle frequency band is 3 x 10^(-21) Hz^(-1/2).
