f(R) gravity constraints from gravitational waves

Understand

The recent LIGO observation sparked interest in the field of gravity wave signals.

• Besides the gravity wave observation the LIGO collaboration used the inspiraling black hole pair to constrain the graviton mass.
• Unlike general relativity, $f(R)$ theories have a characteristic non-zero mass graviton.
• We apply the constraint on the graviton mass to viable $f(R)$ models to find the effects on model parameters.
