PKS 1510-089 is a frequently studied Flat Spectrum Radio Quasar (FSRQ), often showing multi-wavelength quasi-simulataneous observations. We report on the optical and 𝛾 -ray temporal analysis focused on major outburst events (flares) in 2014 – 2015. The 𝛾 -ray flares are characterized by intra-day variability (IDV), with flux doubling times on the scale of hours. Optical/ 𝛾 -ray 𝑧 -transformed Discrete Cross-Correlation Function (ZDCF) analysis revealed significant correlation (>95.45% C.L) between the low and high energy bands, found with near-zero time lags. We determined the minimum Doppler factors from each flare and constrained the 𝛾 -ray emission regions to distances close to the inner boundaries of the broad-line region (BLR) away from the central supermassive black hole (SMBH)","PeriodicalId":510409,"journal":{"name":"Proceedings of High Energy Astrophysics in Southern Africa 2022 — PoS(HEASA2022)","volume":"97 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139177527","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
