Is there a non-stationary γ-ray emission zone 42 pc away from the 3C 279 core?

Víctor M. Patiño-Álvarez, Sergio A. Dzib, Andrei Lobanov +1

We investigate the relationship between the variable gamma-ray emission and jet properties in the blazar 3C 279, by combining the Fermi/LAT data spanning a period of eight years wi…

Long-term optical spectral monitoring of a changing-look AGN NGC 3516 I: Continuum and broad-line flux variability

A. I. Shapovalova, L. C. Popovic, V. L. Afanasiev +11

Here we present the long-term optical spectral monitoring of a changing-look active galactic nuclei (AGN) NGC 3516 that covers 22 years (from 1996 to 2018). We explore a variabilit…
