Blazars are active galactic nuclei (AGNs) with their jets pointing towards our line-of-sight. 3C 454.3 is one of the brightest gamma-ray blazars. We look into the emissions from this blazar at different wavebands to understand the emission mechanism and the relative spatial orientations of the different emission regions. We also quantify the blazar variability at multiple epochs which gives us insight into the sizes of the different emission regions. We analyze the spectral property of the source which revealed the interplay between the disc and jet emissions with signatures of particle acceleration followed by radiative cooling. Finally, we will also look into a possible quasi-periodic oscillation in the 3C 454.3 gamma-ray lightcurve of the source.
