New NIR diagnostic diagrams using [C I]/Paγ and H2 1-0 O(5)/PAH 3.3μm ratios correlate with radiation field hardness and distinguish star formation, AGN, and shock excitation in galaxy nuclei.
XRISM spectroscopy of NGC 4388 shows the Fe Kα line arising from the torus, inner torus edge, and BLR at distinct radii, with absorption revealing a gravitationally bound failed wind.
A population of AGN coronae with magnetization parameters spanning up to σ ~ 10 can reproduce the entire observed diffuse neutrino flux from TeV to PeV energies.
Semi-analytical models show AGN disks produce repeated BBH mergers with a high-mass tail beyond the pair-instability gap, more efficiently at low viscosity, with spin and mass-ratio signatures that can match events like GW190521.
Super-Eddington accretion boosts predicted LISA detections of high-redshift black hole binaries to ~64 per year while dropping ET detections to ~4 per year, compared to ~32 and ~64 under Eddington-limited growth.
Calibrated AGN disk-wind models contribute ≲5% to the CGB above 10 GeV and ≲10% to the CNB at 100 TeV and are unlikely to dominate either background.
A single high-energy neutrino event implies that UHE proton sources must evolve strongly like high-luminosity AGN, but this is disfavored when including null results from other detectors, with proton fraction constrained to about 20% at 20 EeV by composition data.
Hα luminosity functions at z~1.3 and z~2.0 yield faint-end slopes of -1.50 and -1.60, with integrated SFR densities of 0.097 and 0.129 M⊙ yr⁻¹ Mpc⁻³ from a sample of 99 emitters.

Revisiting Disk Winds in Active Galactic Nuclei as an Origin of Cosmic Gamma-ray and Neutrino Backgrounds

Implications of a Cosmogenic Origin of KM3-230213A for Ultra-High-Energy Protons
A single high-energy neutrino event implies that UHE proton sources must evolve strongly like high-luminosity AGN, but this is disfavored when including null results from other detectors, with proton fraction constrained to about 20% at 20 EeV by composition data.
