DESCRIPTION:Speakers: Park June-Gyu (Yonsei Universy\, Seoul\, Republic of
  Korea (South Korea))\n\nThe first direct detection of the gravitational-w
 ave signal GW150914 marked the beginning of gravitational-wave astronomy\,
  and 2025 is the 10th anniversary of this discovery. Over the past decade\
 , the sensitivity of ground-based interferometric detectors has improved s
 ignificantly through continuous instrumental upgrades. As a result\, the o
 bservable distance of the detector network has increased from run to run. 
 While only three events were detected during O1\, by the end of the O4 obs
 erving run on 18 November 2025 a total of about 350 gravitational-wave eve
 nts had been confirmed\, and roughly 200 of them had been analyzed and inc
 luded in published event catalogs. In this talk\, I will review the instru
 mental development of ground-based gravitational-wave detectors over the l
 ast ten years\, with a focus on key optical techniques\, such as dual-recy
 cling interferometer configurations and noise-mitigation schemes. I will a
 lso summarize the main classes of detected sources and discuss several rep
 resentative events that characterize the first decade of gravitational-wav
 e astronomy.\nRemote connection available at:\nhttps://uniroma1.zoom.us/j/
