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…
Swift/UVOT discovery of Swift J221951-484240: a UV luminous ambiguous nuclear transient
S. R. Oates, N. P. M. Kuin, M. Nicholl +57
We report the discovery of Swift J221951-484240 (hereafter: J221951), a luminous slow-evolving blue transient that was detected by the Neil Gehrels Swift Observatory Ultra-violet/O…
A matched-filter approach to radio variability and transients: searching for orphan afterglows in the VAST Pilot Survey
James K. Leung, Tara Murphy, Emil Lenc +5
Radio transient searches using traditional variability metrics struggle to recover sources whose evolution timescale is significantly longer than the survey cadence. Motivated by t…
RadioAstron Space VLBI Imaging of the jet in M87: I. Detection of high brightness temperature at 22 GHz
Jae-Young Kim, Tuomas Savolainen, Petr Voitsik +19
We present results from the first 22 GHz space very-long-baseline interferometric (VLBI) imaging observations of M87 by RadioAstron. As a part of the Nearby AGN Key Science Program…
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…
