摘要：

We report on Owens Valley Radio Observatory (OVRO), WISE, Swift and Fermi-LAT observations of the high redshift blazar CGRaBS J0733+ 0456, from which significant flux variations in radio and infrared (IR), as well as gamma-ray domains, are detected. Particularly, the amplitude of long-term IR variation is over one order of magnitude, and the IR variability timescale can be constrained as short as a few hours in the source frame. The IR and gamma-ray light curves are found to be rather similar, and the strong quasi-simultaneous IR and gamma-ray flares are proven to be unique among the nearby gamma-ray sources. This is the first time that a gamma-ray blazar at redshift z >= 3 with multiwavelength flux variations (flares) is identified. Broadband spectral energy distributions in different flux states are constructed and theoretically described. The gamma-ray flares from some blazars as distant as redshift similar to 5 are expected to be detectable for Fermi-LAT.
