Variability study of blazars with TAUVEX: scope and limitations

The study of variability in blazars is an important tool to understand their energetics. Such a study is required to be made in all bands of spectral energy distribution. Hence, we propose to make UV observations of blazars using the TAUVEX facility for sources in the region vertical bar Dec vertical bar > 50 degrees. These observations will be complemented with simultaneous ground based observations in near IR, optical and radio frequencies using the facilities available in the country. The data will be used to study the nature of emission processes.
