The γ‑ray blazar 3C 279 is studied for its physical conditions, with transparency and rapid variability implying anisotropic high‑energy emission. The study proposes that γ‑rays arise from a relativistic jet via synchrotron self‑Compton emission and examines the expected cross‑frequency variability correlation. The model attributes γ‑ray emission to synchrotron self‑Compton in a relativistic jet, with the same electron population producing both the inverse‑Compton X‑ray spectrum and low‑frequency synchrotron radiation. The γ‑ray spectrum is softer than the X‑ray spectrum due to upper cutoffs in the electron energy distribution along the jet. Published in The Astrophysical Journal (Sept 1992), DOI 10.1086/186531.

Abstract The physical conditions in the γ-ray-emitting blazar 3C 279 are discussed. The requirement of transparency for γ-rays, together with the observation of rapid variability, imply that the high-energy radiation is anisotropic. It is proposed that the γ-rays are produced in a relativistic jet via the synchrotron self-Compton mechanism. The γ-ray spectrum is the high-energy extension of the inverse Compton radiation responsible for the X-ray emission. It is softer than the X-ray spectrum, owing to upper cutoffs in the electron energy spectra along the jet. The same electrons are responsible for the low-frequency emission (10^13^-10^16^ Hz) via synchrotron radiation. The expected correlation of variability at different frequencies is discussed.
