Diagnosing the AGN Origin of Diffuse TeV Neutrinos with Their Spatial Correlation
The Astrophysical JournalThe recent detection of TeV neutrinos from nearby Seyfert galaxies (e.g., NGC 1068) by IceCube suggests that active galactic nuclei (AGNs) could make a significant contribution to diffuse astrophysical neutrinos.

Amplified Cloud‐Phase Responses Over Global Mountain Regions Under Climate Warming
AGU Advances, Volume 7, Issue 6, September 2026.Abstract Changes in cloud phase can substantially affect cloud radiative feedbacks and precipitation processes, yet their responses to climate warming remain poorly understood, particularly over mountain regions. Using 20 years of satellite observations together with ERA5 reanalysis data, this study investigates changes in cloud fraction (CF), cloud ...

Reverberation Mapping Data of NGC 5548 Imply a Multicomponent Broad-line Region
The Astrophysical JournalLine broadening and variability are observational hallmarks of active galactic nuclei (AGN) which allow us to measure supermassive black hole masses as well as constrain the geometry and kinematics of the emitting gas, with the most precise measurements ...

Earth and Space Science, Volume 13, Issue 9, September 2026.Abstract This study develops a novel framework within the Weather Research and Forecast Model for modeling aerosol‐cloud‐lightning interactions. The framework explicitly represent aerosol‐cloud interactions by prescribing aerosols with two configurations: an idealized setup, where both cloud condensation nuclei (CCN) and ice nucleating particles (IN ...

THE ORIENTATION OF THE NUCLEAR OBSCURER OF THE ACTIVE GALACTIC NUCLEI
, 2010 We examine the distribution of axis ratios of a large sample of disk galaxies hosting type 2 active galactic nuclei (AGNs) selected from the Sloan Digital Sky Survey and compare it with a well-defined control sample of non-active galaxies.

Identifying the Secondary Jet in the RadioAstron Image of OJ 287
The Astrophysical JournalThe 136 yr long optical light curve of OJ 287 is explained by a binary black hole model where the secondary is in a 12 yr orbit around the primary. Impacts of the secondary on the accretion disk of the primary generate a series of optical flares that ...

Investigating Layered Cratonic Lithosphere in the Fennoscandian Shield
Geochemistry, Geophysics, Geosystems, Volume 27, Issue 9, September 2026.Abstract Cold, thick, and chemically depleted lithosphere with high seismic velocity and low attenuation characterizes continental cratons. However, discrepancies between xenolith‐based thermal constraints and those inferred from surface‐wave seismic models, together with the widespread observation of mid‐lithosphere discontinuities, challenge the ...

Relation between millimeter wavelengths emission and high-energy emission for active galactic nuclei
, 1998 After comparing the Aux densities of a sample of active galactic nuclei detected fly energetic gamma-ray experiment telescope at 90 and 230 GHz with the gamma-ray emissions detected by Compton Gamma-nay Observatory and x-ray emission, a strong ...
