The Fermi Bubbles. I. Possible Evidence for Recent AGN Jet Activity in the Galaxy
, 2012 The Fermi Gamma-ray Space Telescope reveals two large gamma-ray bubbles in the Galaxy, which extend about 50 degrees (~ 10 kpc) above and below the Galactic center (GC) and are symmetric about the Galactic plane.

Formation of Asteroid (16) Psyche by a Giant Impact
Journal of Geophysical Research: Planets, Volume 131, Issue 1, January 2026.Abstract Asteroid (16) Psyche is the largest likely metal‐rich asteroid in the Solar System and the target of the NASA Psyche mission. The mission aims to determine whether the asteroid is the core of a differentiated planetesimal that lost its mantle via a giant impact.

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

The Origin of Keplerian Megamaser Disks
, 2012 Several examples of thin, Keplerian, sub-parsec megamaser disks have been discovered in the nuclei of active galaxies and used to precisely determine the mass of their host black holes.

Aquaculture Nutrition, Volume 2026, Issue 1, 2026.A high‐level fava beans diet has been proven to enhance the texture characteristics of tilapia muscle, yet it can also induce hepatointestinal injury. Rutin, as a nutritional additive, has antioxidant and immune‐boosting effects. This study explored the regulatory effect of 150 and 300 mg/kg rutin on the muscle characteristics and hepatointestinal ...

Quantifying the Active Galactic Nucleus Fraction in Cosmic Voids via Mid-infrared Variability
The Astrophysical JournalObservations and theoretical simulations suggest that the large-scale environment plays a significant role in how galaxies form and evolve and, in particular, whether and when galaxies host an actively accreting supermassive black hole in their center (i.

The Dense Plasma Torus Around the Nucleus of an Active Galaxy NGC 1052
, 2001 A subparsec-scale dense plasma torus around an active galactic nucleus (AGN) is unveiled. We report on very-long-baseline interferometry (VLBI) observations at 2.3, 8.4, and 15.4 GHz towards the active galaxy NGC 1052.

Continuum Reverberation Mapping of 18 Active Galactic Nuclei over 4 Yr
The Astrophysical JournalContinuum reverberation mapping probes the size scale of the optical continuum-emitting region in active galactic nuclei (AGN). The source of this emission has long been thought to originate from the accretion disk, but recent studies suggest the broad ...
