TeV BL Lacertae objects require extreme relativistic bulk motion in the gamma-ray emission region, but at the VLBI scale their radio knots hardly move. The same sources show evidence, in radio, of a structure made of a fast spine plus a slow layer. We propose that this structure exists even on the spatial scale of regions responsible for the gamma-ray emission. One component sees the (beamed) radiation produced by the other, and this enhances the inverse Compton emission of both components. In addition, this allows the magnetic field to be nearly in equipartition with the emitting particles. The inverse Compton emission of the spine is anisotropic in its frame, possibly producing the deceleration of the spine by the Compton rocket effect. In this scenario, also the slow layer is a relatively strong high energy emitter, and thus radiogalaxies become potentially detectable by GLAST.

Radio-Gamma-Ray Properties and High-Energy Implications for Fermi Blazars
Using 1,687 Fermi blazars, the paper reports a plateau in gamma-ray loudness at high synchrotron peak frequencies, interpreted as Klein-Nishina suppression yielding magnetic field constraints for HBLs.

Fermi-Large Area Telescope Detection of Very High Energy (>100 GeV) Emission from Compton-Dominated Blazars
Systematic Fermi-LAT search detects VHE emission from 14 Compton-dominated blazars (4 new at >5σ) and constrains the emitting region to >1.1–1.4 BLR radii.

The Fundamental Planes of Black Hole Activity for High-Synchrotron-Peaked BL Lacertae Objects
A sample of 69 HBLs yields intrinsic radio-X-ray correlation L_R,int ∝ L_X,int^0.68 and fundamental plane log L_R,int = 0.57 log L_X,int + 0.33 log M_BH + 12.65, consistent with synchrotron cooling model for X-ray emission.

Constraining Orbital Eccentricity of a Supermassive Black Hole Binary Candidate PKS 2131-0211
Bayesian fitting of an eccentric Keplerian orbit to the radio light curve of PKS 2131-021 gives e = 0.053 ± 0.015 without red noise but favors a circular orbit plus DRW noise with e < 0.15.

Active Galactic Nuclei as high-energy neutrino sources
AGN (jetted and non-jetted) are viable high-energy neutrino sources, with TXS 0506+056 and NGC 1068 as the only statistically significant associations so far, while gamma-ray blazars contribute only a small fraction o...
