Quasi-periodic pulsations (QPPs; also known as quasi-periodic oscillations, i.e., QPOs) are electromagnetic emission phenomena that vary quasi-periodically with time. They appear in celestial transient events with different temporal/spatial scales, such as stellar flares, gamma ray bursts and fast radio bursts.
