UHECRs from the Radio Lobes of AGNs
نویسنده
چکیده
We report a stochastic mechanism of particle acceleration from first principles in an environment having properties like those of Radio Lobes in AGNs. We show that energies ∼ 10 eV are reached in ∼ 10 years for protons. Our results reopen the question regarding the nature of the high-energy cutoff in the observed spectrum: whether it is due solely to propagation effects, or whether it is also affected by the maximum energy permitted by the acceleration process itself.

The discoveries of the GZK cutoff with the HiRes and Auger Observatories and the discovery by Auger of clustering of > ∼ 60 EeV ultra-high energy cosmic rays (UHECRs) towards nearby ( < ∼ 75 Mpc) AGNs along the supergalactic plane establishes the astrophysical origin of the UHECRs. The likely sources of the UHECRs are gamma-ray bursts and radio-loud AGNs because: (1) they are extragalactic; (2)...
متن کاملActive Galactic Nuclei, Radio Jets and Acceleration of UHECRs
Most of the galaxies of the Local Universe shine by effect of stellar and interstellar gas emissions, predominantly in the optical band. Typically, the emitted spectra are characterized by stellar absorption lines and emission lines by HII regions. These sources are called Normal Galaxies. A small fraction of galaxies, about 1%, do not follow this behavior. In fact, they show strong and broad e...
متن کاملGamma Ray Bursts and Radio Loud Active Galactic Nuclei
We believe that the radiation we receive from Gamma-Ray Bursts (GRBs) and radio loud Active Galacti Nuclei (AGNs) originates from the transformation of bulk relativistic motion into random energy. Mechanisms to produce, collimate and accelerates the jets in these sources are uncertain, and it may be fruitful to compare the characteristics of both class of sources in search of enlightening simil...
متن کاملUltra High Energy Cosmic Ray and Γ-ray Signatures of Inductive Acceleration in Agn Jets
The highest energy cosmic rays could be produced by drifts in magnetized, cylindrically collimated, sheared jets of powerful active galaxies (i.e. FR II radiogalaxies; radio loud quasars and high power BL Lacs). We show that in such scenarios proton synchrotron radiation can give rise to detectable photon fluxes at energies ranging from hundreds of keV to tens of MeV. Subject headings: AGNs-UHE...
متن کاملUltra-High-Energy Cosmic Rays from the Radio Lobes of AGNs
In the past year, the HiRes and Auger collaborations have reported the discovery of a high-energy cutoff in the ultra-high energy cosmic-ray (UHECR) spectrum, and an apparent clustering of the highest energy events towards nearby active galactic nuclei (AGNs). Consensus is building that such ∼ 10–10 eV particles are accelerated within the radio-bright lobes of these sources, but it is not yet c...
