The Contribution of Turbulent Active Galactic Nucleus Coronae to the Diffuse Neutrino Flux

open access: yesThe Astrophysical Journal
Active galactic nuclei (AGN) can accelerate protons to energies of ∼10–100 TeV, with secondary production of high-energy neutrinos. If the acceleration is driven by magnetized turbulence, the main properties of the resulting proton and neutrino spectra ...

Dynamical Friction Models for Black Hole Binary Formation in Active Galactic Nucleus Disks

open access: yesThe Astrophysical Journal
Stellar-mass black holes (sBHs) embedded in gaseous disks of active galactic nuclei (AGN) can be important sources of detectable gravitational radiation for LIGO/Virgo when they form binaries and coalesce due to orbital decay. In this paper, we study the

Experimental Indicators of Accretion Processes in Active Galactic Nuclei

open access: yes, 2017
Bright Active Galactic Nuclei are powered by accretion of mass onto the super massive black holes at the centers of the host galaxies. For fainter objects star formation may significantly contribute to the luminosity. We summarize experimental indicators

A Reverberation Mapping Study of a Highly Variable Active Galactic Nucleus 6dFGS gJ022550.0-060145

open access: yesThe Astrophysical Journal
We use LCOGT observations (MJD 59434−59600) with a total exposure time of ≃50 hr and a median cadence of 0.5 day to measure the interband time delays (with respect to u ) in the g , r , and i continua of a highly variable active galactic nucleus (AGN ...

Effects of Intrinsic Active Galactic Nucleus Variability on Optical Quasiperiodic Oscillations Related to Subparsec Binary Black Hole Systems in Broad-line Active Galactic Nuclei

open access: yesThe Astrophysical Journal
In this paper, an oversimplified model is proposed to test the effects of intrinsic active galactic nucleus (AGN) variability on expected optical quasiperiodic oscillations (QPOs) related to subparsec binary black hole systems (BBHs) in broad-line AGN ...
