Narrative:
While on a dogleg to final for a visual to 35L in den we had a climb RA when descending through 8500 feet to our cleared altitude of 7000 feet. The first officer (first officer) executed the escape maneuver and we notified ATC we were responding to a climbing RA. ATC had previously called VFR traffic climbing to close to our position. TCAS target showed at our 2 o'clock position at a relative altitude of -500 feet and less than a mile when we responded to the RA. Vertical climb required was in excess of 3500 fpm. We climbed to approximately 10000 feet to clear the conflict. We stabilized; queried ATC; and conducted a visual approach to 35L. Jumpseater was the only one of us to acquire the target visually; a [small aircraft]. On the ground I contacted the approach control supervisor. He stated that there had been a departure from front range (tfg) that was supposed to climb to an altitude below the class B and were investigating. The supervisor later called back and related that the aircraft had violated the class B by over 800 feet and the resulting proximity of his aircraft to ours was quite close.

Title: A320 flight crew reported responding to an RA on a visual approach into DEN when a small aircraft entered Class B airspace without authorization.
Narrative: While on a dogleg to final for a visual to 35L in DEN we had a climb RA when descending through 8500 feet to our cleared altitude of 7000 feet. The First Officer (FO) executed the escape maneuver and we notified ATC we were responding to a climbing RA. ATC had previously called VFR traffic climbing to close to our position. TCAS target showed at our 2 o'clock position at a relative altitude of -500 feet and less than a mile when we responded to the RA. Vertical climb required was in excess of 3500 fpm. We climbed to approximately 10000 feet to clear the conflict. We stabilized; queried ATC; and conducted a visual approach to 35L. Jumpseater was the only one of us to acquire the target visually; a [small aircraft]. On the ground I contacted the Approach control supervisor. He stated that there had been a departure from Front Range (TFG) that was supposed to climb to an altitude below the Class B and were investigating. The supervisor later called back and related that the aircraft had violated the Class B by over 800 feet and the resulting proximity of his aircraft to ours was quite close.
