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

The 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

, 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

Can the Symmetric Fermi and eROSITA Bubbles Be Produced by Tilted Jets?

The Astrophysical Journal
The Fermi Gamma-Ray Space Telescope reveals two large bubbles in the Galaxy, extending nearly symmetrically ∼50° above and below the Galactic center (GC).

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

The 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 ...

Extended Emission-line Region in a Poststarburst Galaxy Hosting Tidal Disruption Event AT2019qiz and Quasiperiodic Eruptions

The Astrophysical Journal
We present a comprehensive analysis of the extended emission-line region (EELR) in the host galaxy of the tidal disruption event (TDE) AT2019qiz, utilizing Very Large Telescope (VLT)/MUSE integral-field spectroscopy.

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

The 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 ...
