The Large-scale Environments of Low-luminosity AGNs at 3.9 < z < 6 and Implications for Their Host Dark Matter Halos from a Complete NIRCam Grism Redshift Survey

The Astrophysical Journal
We study the large-scale environments and clustering properties of 28 low-luminosity active galactic nuclei (AGNs) at z  = 3.9–6 in the GOODS-N field.

Search for High-excitation Emission Lines from a Quasar-scale Active Nucleus in Arp 220

The Astrophysical Journal
The late-stage galaxy merger and prototypical ultraluminous infrared galaxy (ULIRG) Arp 220 is probed using the JWST Mid Infrared Instrument medium-resolution spectrometer to search for multiple diagnostic active galactic nuclei (AGN) emission lines in ...

Revision of Two-temperature Magnetically Arrested Flows onto a Black Hole

The Astrophysical Journal
We revisit the radiative properties of 3D general relativistic magnetohydrodynamics (GRMHD) two-temperature magnetically arrested disk (MAD) models in which electrons are heated by a magnetic turbulent cascade.

Activity and Feeding in Nearby Low Luminosity Galactic Nuclei

, 2014
Throughout the last decades a number of correlations between the proper- ties of the supermassive black holes (SMBH) in the center of galaxies and their hosting galaxies have been found. This suggests that these compo- nents influence each other in their evolution.
