SKAVLBI view of AGN jets in the early Universe

C. Spingola, M. Mezcua, Y. Liu +33

Active Galactic Nuclei (AGN) are among the brightest sources in the Universe, and those that are also jetted are uniquely valuable at the earliest epochs, because their relativisti…

Very Long Baseline Interferometry Search for Nuclear Radio Continuum Emission in the Barred Spiral Galaxy NGC 7479

Seppo Laine, Emmanuel Momjian, Emilia Järvelä +4

We have obtained very high angular resolution (a few milliarcseconds or sub-parsec scale) Very Long Baseline Array (VLBA) and European Very Long Baseline Interferometry (VLBI) Netw…

BLAZ4R and the eROSITA view of z>4 blazars

Tullia Sbarrato, Silvia Belladitta, Julien Wolf +8

We present BLAZ4R, the first living catalog of confirmed blazars, with a focus on the contribution of eROSITA, on board of the Spectrum Roentgen Gamma (SRG) spacecraft. Blaza…

Radio-Near Infrared Imaging of Dual Active Galactic Nuclei Candidates

Makoto A. Johnstone, Ilsang Yoon, Emmanuel Momjian +13

We report the results of a pilot study that searched for dual active galactic nuclei (AGN) in local (0.25) galaxies hosting double-peaked narrow emission lines in their optical…

The radio properties of the JWST-discovered AGN

G. Mazzolari, R. Gilli, R. Maiolino +23

We explore the radio emission of JWST-selected Broad Line AGN (BLAGN, or type 1) in the GOODS-N field. We use deep radio data at different frequencies (144\,MHz, 1.5\,GHz, 3\,GHz,…

Kiloparsec-Scale Alignment of a Radio Jet with Cool Gas and Dust in a z~6 Quasar

Fabian Walter, Eduardo Banados, Chris Carilli +11

We present high-angular resolution (0.068", ~400pc) ALMA imaging of the [CII] line and dust continuum emission of PSO J352.4034-15.3373, a radio-loud quasar at z=5.83. The observat…
