Radio spectra of bright compact sources at z>4.5
Rocco Coppejans, Sjoert van Velzen, Huib T. Intema +10
High-redshift quasars are important to study galaxy and active galactic nuclei (AGN) evolution, test cosmological models, and study supermassive black hole growth. Optical searches…
On the nature of bright compact radio sources at z>4.5
Rocco Coppejans, Sándor Frey, Dávid Cseh +7
High-redshift radio-loud quasars are used to, among other things, test the predictions of cosmological models, set constraints on black hole growth in the early universe and unders…
What are the megahertz peaked-spectrum sources?
Rocco Coppejans, David Cseh, Sjoert van Velzen +8
Megahertz peaked-spectrum (MPS) sources have spectra that peak at frequencies below 1 GHz in the observer's frame and are believed to be radio-loud active galactic nuclei (AGN). We…
Megahertz peaked-spectrum sources in the Boötes field I - a route towards finding high-redshift AGN?
Rocco Coppejans, David Cseh, Wendy L. Williams +2
We present a 324.5MHz image of the NOAO Boötes field that was made using Very Large Array (VLA) P-band observations. The image has a resolution of 5.6x5.1arcsec, a radius of $2.05^…
