  • Investigation of the correlation between optical and γ-ray flux variation in the blazar Ton 599 
    Rajput, Bhoomika; Mandal, Amit Kumar; Pandey, Ashwani; Stalin, C. S; Max-Moerbeck, Walter; Mathew, Blesson (Published by Oxford University Press on behalf of Royal Astronomical Society, 2024-02)
    The correlation between optical and γ-ray flux variations in blazars reveals a complex behaviour. In this study, we present our analysis of the connection between changes in optical and γ-ray emissions in the blazar Ton ...
  • Long term γ-ray variability of blazars 
    Rajput, Bhoomika; Stalin, C. S; Rakshit, S (EDP Sciences, 2020-02)
    We used the data from the Fermi Gamma-ray Space Telescope to characterise the γ-ray flux variability of blazars on month-like time scales. Our sample consists of 1120 blazars of which 481 are flat spectrum radio quasars ...
  • Study of correlation between optical flux and polarization variations in BL Lac objects 
    Rajput, Bhoomika; Pandey, Ashwani; Stalin, C. S; Mathew, Blesson (Oxford University Press on behalf of Royal Astronomical Society, 2022-12)
    Polarized radiation from blazars is one key piece of evidence for synchrotron radiation at low energy, which also shows variations. We present here our results on the correlation analysis between optical flux and polarization ...
  • Temporal correlation between the optical and γ-ray flux variations in the blazar 3C 454.3 
    Rajput, Bhoomika; Stalin, C. S; Sahayanathan, S; Rakshit, S; Amit Kumar Mandal (Oxford University Press on behalf of the Royal Astronomical Society, 2019-06)
    Blazars show optical and γ-ray flux variations that are generally correlated, although there are exceptions. Here we present anomalous behaviour seen in the blazar 3C 454.3 based on an analysis of quasi-simultaneous data ...
