Three-minute Sunspot Oscillations Driven by Magnetic Reconnection in a Light Bridge

We report a different type of three-minute chromospheric oscillation above a sunspot in association with a small-scale impulsive event in a light bridge (LB). During our observations, we found a transient brightening in the LB. The brightening was composed of elementary bursts that may be a manifest...
