An incremental version (4LAC-DR2) of the fourth catalog of active galactic nuclei (AGNs) detected by the Fermi-LAT is presented. This version is associated with the second release of the 4FGL general catalog (based on 10 years of data), where the spectral parameters, spectral energy distributions, yearly light curves, and associations have been updated for all sources. The new reported AGNs include two radio galaxies and 283 blazars. We briefly describe the properties of the new sample and outline changes affecting the previously published sample. Note: Users of this incremental release are requested to cite the original 4LAC paper (Ajello M. et al., 2020, ApJ, 892, 105).

  1. High optical to X-ray polarization ratio reveals Compton scattering in BL Lacertae's jet

    astro-ph.HE 2025-05 conditional novelty 7.0 of 10

    BL Lacertae's record optical polarization with a very low X-ray polarization upper limit favors leptonic Compton-scattering emission and disfavors hadronic models.

  2. Towards a TeV blazar sequence and its physical interpretation

    astro-ph.HE 2025-06 conditional novelty 4.0 of 10

    For the TeV blazar PKS 2155-304, different X-ray data selections lead to very different modeled jet parameters, so claims about the blazar sequence must handle X-ray variability carefully.

  3. Active Galactic Nuclei as high-energy neutrino sources

    astro-ph.HE 2026-06 unverdicted novelty 2.5 of 10

    Review summarizing correlations between astrophysical neutrinos and gamma-ray/radio AGN, specific source associations, proposed production mechanisms, and future prospects.
