Search for the isotropic stochastic background using data from Advanced LIGO's second observing run
The LIGO Scientific Collaboration, the Virgo Collaboration, B. P. Abbott +1133
The stochastic gravitational-wave background is a superposition of sources that are either too weak or too numerous to detect individually. In this study we present the results fro…
