From compact jets to extended lobes: radio morphologies of distant quasars at z > 4
K. Ã. Gabányi, M. Kunert-Bajraszewska, A. Krauze +9
High-redshift quasars play an essential role in studying the growth and evolution of supermassive black holes and active galactic nuclei (AGN). Radio-loud quasars additionally enab…
The SKA-VLBI Perspective on Radio-Quiet AGN
Francesca Panessa, Tao An, James Petley +21
The accretion-ejection mechanism in Active Galactic Nuclei (AGN) remains a central open problem in astrophysics, tied to the role of AGN feedback in galaxy formation and evolution.…
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…
Probing Physical Conditions in Classical and Symbiotic Novae with the Square Kilometre Array Observatory
Rocco Lico, Marcello Giroletti, Arnau Aguasca-Cabot +9
Cataclysmic variables and symbiotic stars are interacting binary systems in which a hot white dwarf (WD) orbits a companion main-sequence or red giant star, respectively. Accumulat…
High-resolution radio imaging of TGSSJ1530+1049, a radio galaxy in a dense environment at z=4
K. Ã. Gabányi, S. Frey, L. I. Gurvits +10
High-redshift radio galaxies can provide insights into the structure formation and galaxy evolution at earlier cosmological epochs. TGSSJ1530+1049 was selected as a candidate high-…
JWST observes the assembly of a massive galaxy at z~4
Aayush Saxena, Roderik A. Overzier, Catarina Aydar +18
We present JWST observations of the radio galaxy TGSSJ1530+1049, spectroscopically confirmed at . NIRCam images and NIRSpec/IFU spectroscopy (R=2700) show that TGSSJ1530+104…
