Abstract: The Cherenkov Telescope Array Observatory (CTAO) is a major next-generation instrument in ground-based gamma-ray astronomy that will become operational in the era of multimessenger astronomy. With its unmatched sensitivity and angular resolution, CTAO will play a pivotal role in the study of transient phenomena in the GeV-TeV range. The Transients Handler is the component within the Array Control and Data Acquisition (ACADA) system that enables CTAO to respond swiftly to alerts about transient events with automatically scheduled observations. The Transients Handler’s tasks include (i) filtering thousands of events per night from multiple external and internal alert streams, (ii) matching these events with scientific proposals, (iii) determining the optimal observation strategy, and (iv) scheduling observations within five seconds of receiving an alert. Recently, in October 2023, the first implementation of the Transients Handler was successfully tested during the integration of ACADA with the first CTAO Large-sized Telescope (LST-1). In this contribution, we will present the design of the Transients Handler in detail and preview updates that will be introduced in the next implementation.
