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…

Milky-Way-like stars in a galaxy core 8 billion years ago revealed by gravitational lensing

Quirino D'Amato, Filippo Mannucci, Alessandro Sonnenfeld +40

The assembly of stellar-dominated cores in elliptical galaxies is key to understanding how cosmic structures evolved. Gravitational lensing offers unique insights into the nature o…

Single- and double-headed odd radio circles in the LOFAR surveys

F. De Gasperin, M. Brüggen, T. Pasini +7

Deep radio surveys are now producing catalogs with millions of radio sources. Radio sources can have complex morphologies that depend on both the production mechanisms and the loca…

An extended and extremely thin gravitational arc from a lensed compact symmetric object at redshift 2.059

J. P. McKean, C. Spingola, D. M. Powell +1

Compact symmetric objects (CSOs) are thought to be short-lived radio sources with two lobes of emission that are separated by less than a kpc in projection. However, studies of suc…

MeerKAT discovery of 164 compact radio rings toward the Galactic Plane

C. Bordiu, F. Bufano, G. Umana +14

We report the discovery of 164 compact (radius < 1 arcmin) radio rings using MeerKAT 1.3 GHz data from the SARAO MeerKAT Galactic Plane Survey (l=2-60deg, 252-358deg, |b|<1.5deg) a…

High- radio Quasars in RACS I: Selection, identification, and multi-wavelength properties

L. Ighina, A. Caccianiga, A. Moretti +21

Radio-bright, jetted quasars at serve as unique laboratories for studying supermassive black hole activity in the early Universe. In this work, we present a sample of high-$z…
