    • Megahertz peaked-spectrum sources in the Boötes field I - a route towards finding high-redshift AGN? 

      Coppejans, Rocco; Cseh, David; Williams, Wendy L.; Velzen, Sjoert van; Falcke, Heino (2015-06-21)
      We present a 324.5MHz image of the NOAO Bo\"otes field that was made using Very Large Array (VLA) P-band observations. The image has a resolution of 5.6x5.1arcsec, a radius of $2.05^\circ$ and a central noise of ~0.2mJy\beam. ...

    • What are the megahertz peaked-spectrum sources? 

      Coppejans, Rocco; Cseh, David; Velzen, Sjoert van; Falcke, Heino; Intema, Huib T.; Paragi, Zsolt; Muller, Cornelia; Williams, Wendy L.; Frey, Sandor; Gurvits, Leonid I.; Kording, Elmar G. (2016-07-01)
      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 recently presented a new method to search ...
