| Description |
Blazars are excellent laboratories to study the environment within the jets of active galactic nuclei, as dominant part of the observed nonthermal emission from AGN originates within them. The emission from the jets of blazars is spread widely across the electromagnetic spectrum from radio wavelengths to gamma-rays. In spite of the progress that has been made to understand the blazar jets, several key questions are still unanswered. Some of the open questions are (i) the content of their jets; (ii) the location and structure of their dominant emission zones; (iii) the origin of observed variability on timescales from minutes to tens of years;(iv) the particle energy distribution and the dominant acceleration mechanism for the underlying radiating particles. I will present results of multiwavelength studies of two nearby TeV blazars Mrk 421 and Mrk 501, to provide insight to the unanswered questions.
