The mysterious alien artifacts found near the landing zone have started glowing neon green.
Use the past participle to reduce a simple passive relative clause ("artifacts which were found").
Any crew members experiencing sudden urges to sing opera must report to the medical bay immediately.
Use the present participle to reduce an active relative clause ("crew members who are experiencing").
The engine repairs currently being done on the outer hull are absolutely critical for our escape.
To reduce a continuous passive relative clause ("repairs which are currently being done"), use being + the past participle. Just using "done" would imply the repairs are already finished, which contradicts the word "currently."
