Blazar Compton Efficiencies

Journal of Physics: Conference Series, 2012
The Fermi gamma-ray space telescope has dramatically increased the number of gamma-ray blazars known and means that for the first time, a large sample of blazars selected by the strength of their inverse Compton emission exists. We have cross-identified the blazars listed in the first Fermi-LAT catalog (1FGL) with the CRATES radio catalogue.

PKS J0805-0111: A Second Owens Valley Radio Observatory Blazar Showing Highly Significant Sinusoidal Radio Variability—The Tip of the Iceberg

The Astrophysical Journal
Owens Valley Radio Observatory observations of the supermassive black hole binary (SMBHB) candidate PKS 2131−021 revealed, for the first time, six likely characteristics of the phenomenology exhibited by SMBHBs in blazars, of which the most unexpected ...

Modeling Blazar Broadband Emission with a Convolutional Neural Network. I. Synchrotron Self-Compton Model

The Astrophysical Journal
Modeling the multiwavelength spectral energy distributions (SEDs) of blazars provides key insights into the underlying physical processes responsible for the emission.

From Equipartition to Curvature: The Spectral Evolution of 4FGL Blazars

The Astrophysical Journal Supplement Series
We investigate the evolution of spectral energy distribution (SED) and underlying electron energy distribution (EED) by modeling the nearly simultaneous broadband spectra of selected bright 4FGL blazars, in the context of a combined cooling and ...

Optical Quasi-Periodic Oscillation of Blazar PKS 1440-389 in the TESS Light Curve

Universe
We report the results of time series analysis of blazar PKS 1440-389, observed by the Transiting Exoplanet Survey Satellite (TESS) in two sectors. We find that the source has a quasi-periodic oscillation (QPO) of about 3.1 days for sector 11 and around 3.
