MOJAVE -- XXII. Brightness temperature distributions and geometric profiles along parsec-scale AGN jets

E. V. Kravchenko, I. N. Pashchenko, D. C. Homan +5

Radial gradients of the brightness temperatures along the parsec-scale jets of Active Galactic Nuclei (AGN) can be used to infer the energy balance and to estimate the parameter ra…

Key Science Goals for the Next-Generation Event Horizon Telescope

Michael D. Johnson, Kazunori Akiyama, Lindy Blackburn +42

The Event Horizon Telescope (EHT) has led to the first images of a supermassive black hole, revealing the central compact objects in the elliptical galaxy M87 and the Milky Way. Pr…

Compact Symmetric Objects -- III Evolution of the High-Luminosity Branch and a Possible Connection with Tidal Disruption Events

A. C. S. Readhead, V. Ravi, R. D. Blandford +18

We use a sample of 54 Compact Symmetric Objects (CSOs) to confirm that there are two unrelated CSO classes: an edge-dimmed, low-luminosity class (CSO~1), and an edge-brightened, hi…

Compact Symmetric Objects -- I Towards a Comprehensive Bona Fide Catalog

S. Kiehlmann, M. L. Lister, A. C. S. Readhead +8

Compact Symmetric Objects (CSOs) are jetted Active Galactic Nuclei (AGN) with overall projected size <1 kpc. The classification was introduced to distinguish these objects from the…

VLBI Scrutiny of a New Neutrino-Blazar Multiwavelength-Flare Coincidence

F. Eppel, M. Kadler, E. Ros +20

In the past years, evidence has started piling up that some high-energy cosmic neutrinos can be associated with blazars in flaring states. On February 26, 2022, a new blazar-neutri…

A New Sample of Gamma-Ray Emitting Jetted Active Galactic Nuclei

Luigi Foschini, Matthew L. Lister, Heinz Andernach +11

We considered the fourth catalog of gamma-ray point sources produced by the Fermi Large Area Telescope (LAT) and selected only jetted active galactic nuclei (AGN) or sources with n…
