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…
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…
First Measurements of Black Hole Accretion and Radio-jet Timescales in a Young Quasar at the Edge of Reionization
SofÃa Rojas-Ruiz, Emmanuel Momjian, Frederick B. Davies +8
We present the first study dedicated to measuring the timescales for black hole accretion and jet launch in a quasar at the edge of Reionization, PSO J352.4034-15.3373 at z = 5.832…
