Investigation of the correlation between optical and -ray flux variation in the blazar Ton 599

Bhoomika Rajput, Amit Kumar Mandal, Ashwani Pandey +3

The correlation between optical and -ray flux variations in blazars reveals a complex behaviour. In this study, we present our analysis of the connection between changes in opti…

Unprecedented extreme high-frequency radio variability in early-stage active galactic nuclei

E. Järvelä, T. Savolainen, M. Berton +9

We report on the discovery of one of the most extreme cases of high-frequency radio variability ever measured in active galactic nuclei (AGN), observed on timescales of days and ex…

Variability studies of active galactic nuclei from the long-term monitoring program with the Cherenkov Telescope Array

Guillaume Grolleron, Josefa Becerra González, Jonathan Biteau +13

Blazars are active galactic nuclei (AGN) with a relativistic jet oriented toward the observer. This jet is composed of accelerated particles which can display emission over the ent…
