| Outline of Final Research Achievements |
The extragalactic background light and the very high energy gamma-ray emission from cosmological distant objects such as Flat Spectrum Radio-loud Quasars (FSRQ) located at the redshift of z ~ 1 away from the earth have been studied.
Results from multiwavelength observations led by the imaging atmospheric Cherenkov telescope MAGIC on the FSRQ object PKS 1510-089 was published in the Astronomy and Astrophysics journal. Furthermore, a very high energy gamma-ray signal from two objects, a most distant object ever S3 0218+357 which have a redshift of z = 0.94 and H 1722+119 whose redshift is estimated to be >0.5, was discovered.
