A Hierarchical Shock Model of Ultra-High-Energy Cosmic Rays
Paul Simeon, Noémie Globus, Kirk S. S. Barrow +1
We propose that a hierarchical shock model$\unicode{x2014}$including supernova remnant shocks, galactic wind termination shocks, and accretion shocks around cosmic filaments and ga…
Relativistic Jets and Winds in Radio-Identified Supermassive Black Hole Binary Candidates
Andrew G. Sullivan, Roger D. Blandford, Anna Synani +4
Supermassive black hole binary systems (SMBHBs) are thought to emit the recently discovered nHz gravitational wave background; however, not a single individual nHz source has been…
Atacama Cosmology Telescope: Observations of supermassive black hole binary candidates. Strong sinusoidal variations at 95, 147 and 225 GHz in PKS 2131021 and PKS J08050111
Adam D. Hincks, Xiaoyi Ma, Przemek Mróz +23
Large sinusoidal variations in the radio light curves of the blazars PKS J08050111 and PKS 2131021 have recently been discovered with an 18-year monitoring programme at the O…
Fermi detection of gamma-ray Emission from the Hot Coronae of Radio-quiet Active Galactic Nuclei
Jun-Rong Liu, Jian-Min Wang, Fermi-LAT Collaboration
Relativistic jets around supermassive black holes (SMBHs) are well-known powerful -ray emitters. In absence of the jets in radio-quiet active galactic nuclei (AGNs), how the SM…
Ultra High Energy Cosmic Rays
Noémie Globus, Roger Blandford
Ultra High Energy Cosmic Rays, UHECR, are charged particles with energies between and . They exhibit fundamenta…
PKS 2131-021 -- Discovery of Strong Coherent Sinusoidal Variations from Radio to Optical Frequencies: Compelling Evidence for a Blazar Supermassive Black Hole Binary
S. Kiehlmann, P. V. de la Parra, A. G. Sullivan +31
Haystack and Owens Valley Radio Observatory (OVRO) observations recently revealed strong, intermittent, sinusoidal total flux-density variations that maintained coherence between 1…
