Discovery of an HI 21 cm absorber at z=0.882 towards PKS 0405-385 with associated MgII/FeII lines at the same redshift plus two other metal systems, and a revised quasar linear size >0.3 pc with no repeating intraday variability.
Spectral hardening in PKS 2155-304 appears only at the QPO flux minimum because geometric de-boosting suppresses the soft emission component.
Fermi-LAT variability analysis of jetted AGNs finds mean damping timescales of ~100 days, greater amplitudes in FSRQs than BL Lacs, emission regions at 2-4.5 R_DT but 123-295 R_BLR, and correlations with luminosities, loudness, black hole mass, and Eddington ratio.
Spectral index maps of the limb-brightened jet in 3C 84 show significant evolution across three epochs, indicating dynamic filamentary structures, evolving magnetic fields, and interaction with the ambient medium.

Characterizing the origins of gamma-ray variability of the jetted active galactic nuclei observed with the Fermi-LAT
Fermi-LAT variability analysis of jetted AGNs finds mean damping timescales of ~100 days, greater amplitudes in FSRQs than BL Lacs, emission regions at 2-4.5 R_DT but 123-295 R_BLR, and correlations with luminosities, loudness, black hole mass, and Eddington ratio.
