Inflation, space-borne interferometers and the expansion history of the universe

HIGHLIGHTS

• who: Massimo Giovannini from the Department of Physics, CERN, Geneva, Switzerland have published the research work: Inflation, space-borne interferometers and the expansion history of the Universe, in the Journal: Eur. Phys. J. C (2022) 82:828 of /2022/
• what: In this analysis the authors show that this conclusion is evaded if prior to nucleosynthesis the post-inflationary evolution includes a sequence of stages expanding either faster or slower than radiation. The authors are instead concerned with the mHz range and the potential signal from pulsar timing arrays will not be specifically discussed. parameter space . . .
