Human Factors; Procedure
At just after XA00Z descending to 9;000 feet; while being vectored from ZZZ Approach to intercept the final approach course for Runway XXR at ZZZ we experienced an RA. Just before the aircraft alerted us to the resolution; the Controller started to give us a traffic alert but his radio call was overtaken by the aircraft resolution audio and we began the immediate climb. We only saw the conflict aircraft for a matter of seconds on the TCAS before we realized he was climbing into our descent. The resolution had us climb the airplane to an eventual altitude of 9;700 feet before alerting us that we were clear of conflict. We advised the Controller that we were responding to an RA and when we were clear of the conflict. He continued our vectors and released us to ZZZ Tower soon after; where we advised him a second time that we had experienced a RA. We landed at ZZZ without further incident.
Falcon 900 Captain reported responding to a TCAS Resolution Advisory to climb; avoiding another aircraft that was only detected by the TCAS system for a matter of seconds.
