Due to the small jet to line of sight angle, the emission from jet is significantly Doppler boosted and exhibits high luminosities. Blazars emit radiation throughout the electromagnetic spectrum and their observed flux exhibits variations at different time intervals. Observationally, blazars are further subclassified as Flat Spectrum Radio Quasars (FSRQs) and BL Lacertae (BL Lac) objects. BL Lacs are further classified low-synchrotron peaked (LSP), intermediated-synchrotron peaked (ISP) and high-synchrotron peaked (HSP) BL Lacs. This study is primarily focused on the short-term behaviour of sources from different subclasses of blazars in multi-waveband. List of blazars are selected with adequate coverage across electromagnetic waveband. A systematic study is carried out across the different blazar subclasses to examine their nature of variability. The observations in γ-ray band from Fermi-LAT, X-ray and UV band from SWIFT-XRT and UVOT, optical data from SMARTS optical near IR monitoring program and Catalina sky survey and other space and ground observatories are used in this work. The preliminary results of our study is presented here. |
