TELAMON: Effelsberg Monitoring of AGN Jets with Very-High-Energy Astroparticle Emissions -- Polarization properties

J. Heßdörfer, M. Kadler, P. Benke +33

We present recent results of the TELAMON program, which is using the Effelsberg 100-m telescope to monitor the radio spectra of active galactic nuclei (AGN) under scrutiny in astro…

The Impact of Southern-Hemisphere Radio Blazar Observations on Neutrino Astronomy

F. Rösch, P. Benke, M. Kadler +6

The origin of high-energy cosmic neutrinos detected by the IceCube observatory is a hotly debated topic in astroparticle physics. There is growing evidence that some of these neutr…

The peculiar variable X-ray spectrum of the active galactic nucleus PKS 2005-489

Owen Chase, Felicia McBride, Andrea Gokus +4

PKS 2005-489 is a well-known, bright southern BL Lac object that has been detected up to TeV energies. In a low-flux state it exhibits the expected multiwavelength double-peaked sp…

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…

The Fourth Catalog of Active Galactic Nuclei Detected by the Fermi Large Area Telescope -- Data Release 3

LAT collaboration, Marco Ajello, Luca Baldini +100

An incremental version of the fourth catalog of active galactic nuclei (AGNs) detected by the Fermi-Large Area Telescope is presented. This version (4LAC-DR3) derives from the thir…

A Gamma-ray Pulsar Timing Array Constrains the Nanohertz Gravitational Wave Background

M. Ajello, W. B. Atwood, L. Baldini +129

After large galaxies merge, their central supermassive black holes are expected to form binary systems whose orbital motion generates a gravitational wave background (GWB) at nanoh…
