No slip gravity in light of LISA standard sirens
  Standard sirens (SS) are the gravitational wave analog of the astronomical
standard candles, and can provide powerful information about the dynamics of
the Universe up to very high $z$ values. In this work, we generate three mock
SS catalogs based on the merger of massive black hole binaries which are
expected to be observed in the LISA operating frequency band. Then, we perform
an analysis to test modifications of general relativity (GR) inspired by the No
Slip Gravity framework. We find that in the best scenarios, we can constrain
the free parameters which quantify deviations from GR to 21\% accuracy, while
the Hubble parameter can be simultaneously fit to 6\% accuracy. In combination
with CMB information, we find a 15\% accuracy on the modified gravity free
parameters and 0.7\% accuracy on the Hubble parameter. Therefore, the SS events
at very large cosmological distances to be observed in LISA band will provide a
unique way to test nature of gravity.
