Oscillatory patterns in the light curves of 5 long-term monitored type 1 AGN
Andjelka B Kovacevic, Ernesto Perez-Hernandez, Luka C. Popovic +3
A new combined data of 5 well known type 1 AGN are probed with a novel hybrid method in a search for oscillatory behavior. Additional analysis of artificial light curves obtained f…
Low ionospheric reactions on tropical depressions prior hurricanes
Aleksandra Nina, Milan Radovanović, Boško Milovanović +3
We study the reactions of the low ionosphere during tropical depressions (TDs) which have been detected before the hurricane appearances in the Atlantic Ocean. We explore 41 TD eve…
Periodicity in the continua and broad line curves of a quasar E1821+643
Andjelka Kovacevic, Luka C. Popovic, Alla I. Shapovalova +1
Here we present an in-depth analysis of the periodicity of the continua and broad emission lines of a quasar E1821+643. We applied non-parametric composite models, the linear sum o…
