Description
Blazars are very bright extragalactic objects whose luminous intensity is variable in differents frequency-band spectra. It has been observed that PG1553+113 presents the same quasi-periodic variability in all the bands analyzed. One possible explanation for this behavior is that PG1553+113 is a binary black holes system. In this work it is proposed to improve the binary black hole model taking into account relativistic effects in addition to looking for new candidates whose variability can be explained in this way.
