We study responses of the Brans-Dicke field due to gravitational collapses of scalar field pulses using numerical simulations.
- Double-null formalism is employed to implement the numerical simulations.
- If we supply a scalar field pulse, it will asymptotically form a black hole via dynamical interactions of the Brans-Dicke field.
- Hence, we can observe the responses of the Brans-Dicke field by two different regions.
