Multiwavelength Study of the Quiescent States of Six Brightest Flat Spectrum Radio Quasars detected by Fermi-LAT
Abhradeep Roy, Sonal R. Patel, Arkadipta Sarkar +2
The regular monitoring of flat-spectrum radio quasars (FSRQs) in -rays by Fermi-LAT since past 12 years indicated six sources who exhibited extreme -ray outbursts crossing da…
Multi-waveband quasi-periodic oscillations in the light curves of blazar CTA 102 during its 2016-2017 optical outburst
Arkadipta Sarkar, Pankaj Kushwaha, Alok C. Gupta +2
Quasi-periodic fluctuations in the light curves of blazars can provide insight into the underlying emission process. This type of flux modulation hints at periodic physical process…
A Possible -ray Quasi-periodic Oscillation of 314 days in the Blazar OJ 287
Pankaj Kushwaha, Arkadipta Sarkar, Alok C. Gupta +3
We report the detection of a probable -ray quasi-periodic oscillation (QPO) of around 314 days in the monthly binned 0.1 -- 300 GeV -ray {\it Fermi}-LAT light curve of the we…
Multiwaveband Quasi--periodic Oscillation in the Blazar 3C 454.3
Arkadipta Sarkar, Alok C. Gupta, Varsha R. Chitnis +1
We report the detection () of a Quasi-Periodic Oscillation (QPO) in the -ray light curve of 3C 454.3 along with a simultaneous marginal QPO detection () in the optic…
Long term variability and correlation study of the blazar 3C 454.3 in radio, NIR and optical wavebands
A. Sarkar, V. R. Chitnis, A. C. Gupta +11
We performed a long-term optical (B, V, R bands), infra-red (J and K bands) and radio band (15, 22, 37 GHz band) study on the flat spectrum radio quasar, 3C 454.3, using the data c…
