TL;DR: In this paper, the ability of the LISA to measure the cosmological gravitational wave (SGWB) background was analyzed, considering leading models of the string networks, and it was shown that LISA will be able to probe cosmic strings with tensions Gμ>rsim ǫ(10−17), improving by about 6 orders of magnitude current pulsar timing arrays (PTA) constraints.

TL;DR: In this paper, the ability of the LISA to measure the cosmological gravitational wave (SGWB) background is analyzed, considering leading models of the string networks, and it is shown that LISA will be able to probe cosmic strings with tensions $G\mu \gtrsim \mathcal{O}(10^{-17})$, improving by about $6$ orders of magnitude current pulsar timing arrays (PTA) constraints, and potentially $3$ orders with respect to expected constraints from next generation PTA observatories.

TL;DR: In this paper, the authors place observational constraints on slow-variation single-field inflationary models by carrying out the cosmological Monte Carlo simulation with the recent data of Planck combined with the WMAP large-angle polarization, baryon acoustic oscillations, and ACT/SPT temperature data.

TL;DR: The Deci-hertz Interferometer Gravitational Wave Observatory (DECIGO) is a future Japanese space mission with a frequency band of 0.1 Hz to 10 Hz as discussed by the authors.
