Investigating the multiwavelength behaviour of the flat spectrum radio quasar CTA 102 during 2013-2017

F. D'Ammando, C. M. Raiteri, M. Villata +94

We present a multiwavelength study of the flat-spectrum radio quasar CTA 102 during 2013-2017. We use radio-to-optical data obtained by the Whole Earth Blazar Telescope, 15 GHz dat…

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…
