Scalar-Induced Gravitational Waves in Modified Gravity
Anjali Abirami Kugarajh, Marisol Traforetti, Andrea Maselli +2
Scalar-Induced Gravitational Waves (SIGWs), second-order tensor modes sourced by first-order scalar fluctuations in General Relativity (GR), are expected to contribute to the Stoch…
