Probing the High-frequency Variability of NGC 5044: The Key to Active Galactic Nucleus Feedback

The Astrophysical Journal
The active galactic nucleus (AGN) feeding and feedback process in the centers of galaxy clusters and groups is still not well understood. NGC 5044 is the ideal system in which to study AGN feedback. It hosts the largest known reservoir of cold gas in any

Discovering the Mass-Scaled Damping Timescale from Microquasars to Blazars

The Astrophysical Journal Letters
Studying the variability of the accretion disks of black holes and jets is important to identify their internal physical processes. In this Letter, we obtain the characteristic damping timescale of 34 blazars and 7 microquasars from the Fermi-Large Area ...

Driver behind the bimodal distribution of Eddington-scaled radio luminosity in nearby early-type galaxies

Astronomy & Astrophysics
Context. Early-type galaxies host low-luminosity active galactic nuclei, as indicated by radio emission spanning up to several orders of magnitude in terms of the physical scale, ranging from compact parsec-scale to extended kiloparsec-scale radio ...

Modeling Cosmological Evolution of Jetted Seyfert Galaxies for z ≲ 10

The Astrophysical Journal
We use high-resolution cosmological zoom-in simulations to model mechanical and thermal feedback from active galactic nuclei onto the evolution of Seyfert-type galaxies, studying the morphology of central galaxies growing within dark matter (DM) halos ...

Active Galactic Nucleus Jet-inflated Bubbles as Possible Origin of Odd Radio Circles

The Astrophysical Journal
Odd radio circles (ORCs) are newly discovered extragalactic radio objects with an unknown origin. In this work, we carry out three-dimensional cosmic-ray (CR) magnetohydrodynamic simulations using the FLASH code and predict the radio morphology of end-on
