A multiwavelength temporal and spectral analysis of flares of 3C 279 during November 2017–July 2018 are presented in this work .
Three bright gamma-ray flares were observed simultaneously in X-ray and Optical/UV along with a prolonged quiescent state .
A “ harder-when-brighter ” trend is observed in both gamma-rays and X-rays during the flaring period .
The gamma-ray light curve for all the flares are binned in one-day time bins and a day scale variability is observed .
Variability time constrains the size and location of the emission region to 2.1 \times 10 ^ { 16 } cm and 4.4 \times 10 ^ { 17 } cm , respectively .
The fractional variability reveals that the source is more than 100 % variable in gamma-rays and it decreases towards the lower energy .
A cross-correlation study of the emission from different wavebands is done using the DCF method , which shows a strong correlation between them without any time lags .
The zero time lag between different wavebands suggest their co-spatial origin .
This is the first time 3C 279 has shown a strong correlation between gamma-rays and X-rays emission with zero time lag .
A single zone emission model was adopted to model the multiwavelength SEDs by using the publicly available code GAMERA .
The study reveals that a higher jet power in electrons is required to explain the gamma-ray flux during the flaring state , as much as , ten times of that required for the quiescent state .
However , more jet power in magnetic field has been observed during the quiescent state compared to the flaring state .
