Long-term BVR I monitoring of PKS 2155-304 finds significant multi-timescale variability, spectral hardening, a 2023 flare, weak optical-X-ray correlations, and no significant short-term quasi-periodicity once red noise is modelled.

PKS 2155-304: Long-Term Optical Photometric Monitoring and Variability Analysis
Long-term BVR I monitoring of PKS 2155-304 finds significant multi-timescale variability, spectral hardening, a 2023 flare, weak optical-X-ray correlations, and no significant short-term quasi-periodicity once red noise is modelled.
