BL Lac objects are active galactic nuclei notable for a beamed nonthermal radiation, which
is generated in one of the relativistic jets forming a small angle to the observer's line-of-sight …

While there has been an increase in interest in the possibility of quasiperiodic oscillations
(QPOs) in blazars, the search has hitherto been restricted to sources with well-sampled light …

Since humanity first gazed upon the night sky, our curiosity has perpetually sought to unveil
the mysteries concealed beyond the celestial canopy of dark, starry expanse. We developed …

In this thesis, a model for interpreting quasi-periodic signatures originating from
supermassive binary black hole inspirals at the cores of blazars and caused by jet …
