abstract

The OVRO 40-m telescope has been monitoring the 15 GHz radio flux density of over 1200 blazars since 2008. The 15 GHz light curve of the flat spectrum radio quasar J1359+4011 shows a strong and persistent quasi-periodic oscillation. The time-scale of the oscillation varies between 120 and 150 days over a $\sim4$ year time span. We interpret this as the active galactic nucleus mass-scaled analog of low-frequency quasi-periodic oscillations from Galactic microquasars, or as evidence of modulation of the accretion flow by thermal instabilites in the "inner" accretion disc.

  1. Kinematic Stratification in Extremely Red Quasars Revealed by JWST

    astro-ph.GA 2026-05 unverdicted novelty 6.0

    JWST observations of ERQs show stratified gas kinematics via deblended optical emission lines, with UV lines dominated by scattered light and optical lines mixing scattered and obscured emission.

    astro-ph.HE 2026-04 unverdicted novelty 6.0

    Detection of a persistent ~433-day optical QPO in blazar 3C 454.3 at 2.53σ significance using Lomb-Scargle, WWZ, and PDM methods, with a new test for seasonal gaps.

  3. Detection of Quasiperiodic Oscillations in the Blazar PKS 0735+178 with TESS

    astro-ph.HE 2026-07 conditional novelty 4.0

    A transient ~11.2-hour optical QPO is detected in blazar PKS 0735+178 at 3-4 sigma significance using TESS sectors 71-72.
