Study of Blazars Across Electromagnetic Spectrum

The X-ray sky is populated with various fascinating objects, many of which are variable or transient. Blazars are the most variable class of the Active Galactic Nuclei (AGN). Study of this kind of objects with standard instrumentation is difficult. We will introduce the Lobster Eye X-ray telescope (LET), an ideal tool for studying variable, transient, and rare events. We will discuss the possibilities of AGN/blazar studies with this new class of X-ray instruments. Additionally, we demonstrate a possible future application of LET data to study the unique variability of blazars by the means of variogram analysis. We present preliminary results of optical light curve analysis of object 1ES 2344+514 and discuss our future plans.
