MEGA Mass Assembly with JWST: The MIRI EGS Galaxy and Active Galactic Nucleus Survey

The Astronomical Journal
We present the Mid-Infrared Instrument (MIRI) Extended Groth Strip (EGS) Galaxy and Active Galactic Nucleus (MEGA) survey, a four-band MIRI survey with 25 pointings in the EGS extragalactic field.

Sizes of Active Galactic Nucleus Inhomogeneous Disks—Large in Microlensing, Small in Reverberation Mapping

The Astrophysical Journal
Magnetohydrodynamic turbulence can drive significant temperature fluctuations in the accretion disk of an active galactic nucleus (AGN). As a result, the disk can be highly inhomogeneous and has a half-light radius larger than the static Shakura and ...

Optically Thick Jet Base and Explanation of Edge Brightening in Active Galactic Nucleus Jets

The Astrophysical Journal
The jet cores in active galactic nuclei (AGNs) are resolved and found to harbor an edge-brightened structure where the jet base appears extended at the sides compared to its propagation axis. This peculiar phenomenon invites various explanations. We show

A New Framework for Active Galactic Nucleus Accretion and Jet Feedback in Numerical Simulations

The Astrophysical Journal Supplement Series
Accurate modeling of active galactic nucleus (AGN) feedback, especially due to relativistic jets, is crucial for understanding the cool-core problem in galaxy clusters.
