Space-based gravitational-wave detectors can determine the thermal history of the early Universe
Space-based gravitational-wave detectors can determine the thermal history of the early Universe
It is shown that space-based gravitational-wave detectors such as DECIGO and/or the Big Bang Observer will provide us with invaluable information on the cosmic thermal history after inflation, and they will be able to determine the reheat temperature ${T}_{R}$ provided that it lies in the range preferred by the cosmological …
