Over three quarters in 2010-2011, Kepler monitored optical emission from four active galactic nuclei (AGN) with ~30 min sampling, >90% duty cycle, and <~0.1% repeatability. These data determined the AGN optical fluctuation power spectral density functions (PSDs) over a wide range in temporal frequency. Fits to these PSDs yielded power law slopes of -2.6 to -3.3, much steeper than typically seen in the X-rays. We find evidence that individual AGN exhibit intrinsically different PSD slopes. The steep PSD fits are a challenge to recent AGN variability models but seem consistent with first order MRI theoretical calculations of accretion disk fluctuations.

  1. AGN Reverberation Mapping with LITMUS: Fundamental Limits on lag Recovery Rates

    astro-ph.CO 2026-08 conditional novelty 7.0 of 10

    A Bayesian re-analysis of 906 OzDES AGN finds that previous reverberation lags, especially for MgII and CIV, are often false positives, with only 3-28% of MgII sources showing simple lags.

  2. A hierarchical Bayesian framework for cosmology using Type 1 AGN variability

    astro-ph.CO 2026-06 unverdicted novelty 7.0 of 10

    A hierarchical Bayesian framework that uses the empirical anti-correlation between AGN variability amplitude and luminosity to infer cosmological parameters from moderate-baseline light curves via importance reweighting.

  3. Simultaneous radio, optical and X-ray monitoring of hard X-ray selected AGN: a variability study

    astro-ph.HE 2026-07 conditional novelty 6.0 of 10

    In 14 hard-X-ray-selected AGN monitored for two years, variability is strongest in X-rays and weakest in radio, and source variability explains only ~2-3% of the scatter in the Fundamental Plane.

  4. A Disappearing Act: Constraints From "Missing" Flares of Repeating Partial TDE Candidates

    astro-ph.HE 2026-06 unverdicted novelty 6.0 of 10

    Non-detections of expected third flares in TDE 2022dbl and TDE 2020vdq support rpTDE interpretation over independent events, with modeling favoring bound main-sequence star orbits and deep initial encounters.

  5. Continuum optical-UV and X-ray variability of AGN: current results and future challenges

    astro-ph.HE 2025-06 unverdicted novelty 1.0 of 10

    A comprehensive review of AGN continuum variability from optical/UV to X-rays, with no new data.
