Investigation of Loud Transient Noise Sources in aLIGO

The aLIGO detectors are currently undergoing a period of upgrades in preparation for the fourth observation run. In previous observation runs, loud transient noise (or loud glitches) riddled the detector data. Loud glitches occur in the same frequency bandwidth as astrophysical gravitational wave (GW) sources and occur frequently enough to trigger false GW detections. The sources of these glitches are currently unknown. In this talk, I will present results from investigations into the potential sources of loud transient noise.
