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…

Exploring Compact Symmetric Objects with Complex Morphologies

E. E. Sheldahl, G. B. Taylor, S. E. Tremblay +9

Compact symmetric objects (CSOs) are a unique class of jetted active galactic nuclei (AGN) defined by sub-kpc radio emission, showing radio structure on both sides of the central e…

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…

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 SMB…

The Radio Spectra of High Luminosity Compact Symmetric Objects (CSO-2s): Implications for Studies of Compact Jetted Active Galactic Nuclei

P. V. de la Parra, A. C. S Readhead, T. Herbig +18

This paper addresses, for the first time, a key aspect of the phenomenology of Compact Symmetric Objects (CSOs) -- the characteristics of their radio spectra. We present a radio-sp…
