Undetected AGN observed by the MAGIC telescopes

Active galactic nuclei are among the most powerful sources of luminosity in the Universe. Ob- servations of these astrophysical objects are important due to different physical processes and acceleration of particles that can occur. The main goal of this research is the analysis of active galactic nuclei that have been observed by MAGIC telescopes but not detected. Analysis of MAGIC observations of CTA102 was performed, and confirmed no detection. Based on data observed by MAGIC and Fermi-LAT telescopes, sources of particular interest are selected to be discussed in a detail : 3c454.3 and 4C+55.17, including CTA102. Light curves observed by Fermi-LAT space telescope with corresponding spectral indices are pre- sented for these sources. Observations of CTA102, are used in order to extrapolate Fermi spectrum into VHE range.
