Building a Radio AGN Sample from Cosmic Morning -- The Radio High-Redshift Quasar Catalog (RHzQCat): I. Catalog from SDSS Quasars and Radio Surveys at
Yingkang Zhang, Ruqiu Lin, Krisztina Perger +5
Radio-loud high-redshift quasars (RHRQs) provide crucial insights into the evolution of relativistic jets and their connection to the growth of supermassive black holes. Beyond the…
High-resolution radio imaging of TGSSJ1530+1049, a radio galaxy in a dense environment at z=4
K. É. 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…
What Do Radio Emission Constraints Tell Us About Little Red Dots as Tidal Disruption Events?
Krisztina Perger, Judit Fogasy, Sándor Frey
The real nature of little red dots (LRDs), a class of very compact galaxies in the early Universe recently discovered by the James Webb Space Telescope, is still poorly understood.…
Radio emission from flaring stars and brown dwarfs
K. Perger, B. Seli, K. Vida
Aims. With the aim to reveal the effects of the magnetic field to the multi-band activity of dwarf stars, we search for associated radio emission for an extensive list of 14 915 br…
Zooming into the neutrino-associated blazar candidate J1718+4239
K. Perger, S. Frey, K. É. Gabányi +1
The radio quasar NVSS~J171822+423948 (J1718+4239) was proposed as the counterpart of the IceCube neutrino event IC-201221A. To reveal the nature of the source, we conducted new ver…
