英文摘要We revisit the idea that the Galactic Center (GC) is the dominant source of galactic cosmic rays (GCRs), based on a series of new observational evidence. A unified model is proposed to explain the new phenomena of GCRs and gamma-rays simultaneously. The GCRs are thought to be accelerated during past activities of the GC. The pair production process of GCRs in the strong radiation field due to the GC activity is responsible for the knee structure of the CR spectra. A fraction of e(+)e(-) produced by pair production interactions can be reaccelerated in the induced bipolar jets and be transported into the halo, leaving the Fermi gamma-ray bubbles and WMAP microwave haze as the remnant signal. Finally, the CRs diffuse in the bulge could further interact with the interstellar medium to produce low energy e(+)e(-). After cooling down, these positrons may annihilate to produce the 511 keV line emission as discovered by INTEGRAL.
