Multiple Emission Regions in Jets of the Low-Luminosity Active Galactic Nucleus in NGC 4278

open access: yesThe Astrophysical Journal
The Large High Altitude Air Shower Observatory (LHAASO) has detected very-high-energy gamma rays from the low-ionization nuclear emission-line region galaxy NGC 4278, which has a low-luminosity active galactic nucleus (LLAGN) and symmetric, mildly ...

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

open access: yesThe 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).

How to Turn Jets into Cylinders near Supermassive Black Holes in 3D General Relativistic Magnetohydrodynamic Simulations

open access: yesThe Astrophysical Journal Letters
Accreting supermassive black holes (SMBHs) produce highly magnetized relativistic jets that tend to collimate gradually as they propagate outward. However, recent radio interferometric observations of the 3C 84 galaxy reveal a stunning, cylindrical jet ...
