PKS 2155-304: Long-Term Optical Photometric Monitoring and Variability Analysis
J. L. Weiss, I. Andruchow, E. J. Marchesini +6
Through the detailed study of the optical flux behaviour in blazars over time, it is possible to infer the conditions responsible for their observed emission. PKS 2155-304, a BL La…
Microvariability in AGNs: study of different statistical methods II. Light curves from simulated images
L. Zibecchi, I. Andruchow, S. A. Cellone +1
In a previous paper, we studied two statistical methods used to analyse the variability of active galactic nuclei (AGNs): the C and F statistics. Applying them to observed differen…
Microvariability in AGNs: study of different statistical methods - I. Observational analysis
L. Zibecchi, I. Andruchow, S. A. Cellone +3
We present the results of a study of different statistical methods currently used in the literature to analyse the (micro)variability of active galactic nuclei (AGNs) from ground-b…
Optical flux behaviour of a sample of Fermi blazars
E. J. Marchesini, I. Andruchow, S. A. Cellone +7
Aims: We aim at investigating the time-behaviour of a sample of gamma-ray blazars. We present the results from a 13 month-long optical photometry monitoring campaign of the blazars…
