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).

Simple relations from complex outflows: How the M−σ relation emerges in a multi-phase environment

Astronomy & Astrophysics
Context. The tight empirical M − σ relation between the mass of a supermassive black hole (SMBH) and the velocity dispersion of the host galaxy bulge is often interpreted as the result of self-regulation via active galactic nucleus (AGN) feedback.

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.

Spectroscopic analysis and modeling of quasar 3C-279

Tecnociencia
We analyze the X-ray and ultraviolet emission of the AGN 3C-279 using Swift data. Located 5 billion light-years away at a redshift distance of Z=0.537, 3C-279 is a bright AGN powered by a relativistic jet from its supermassive black hole and served as a

Star formation around active galactic nuclei [PDF]

Active galactic nuclei (Seyfert nuclei and their relatives) and intense star formation can both deliver substantial amounts of energy to the vicinity of a galactic nucleus.

Resolving a Candidate Dual Active Galactic Nucleus with ∼100 pc Separation in MCG-03-34-64

The Astrophysical Journal
We report the serendipitous multiwavelength discovery of a candidate dual black hole system with a separation of ∼100 pc, in the gas-rich luminous infrared galaxy MCG-03-34-64 ( z = 0.016).
