These objects were claimed to be associated with nearby galaxies by Harold Arp.
These objects were claimed to be associated with nearby galaxies by Harold Arp. Maarten Schmidt, who also discovered that these objects were more common in the early universe, and Bev Oke discovered the first type of this object, which was called 3C 273. The suppression of wavelengths below the Lyman Alpha line in these object's spectra is known as the Gunn-Peterson trough. Gavitational lensing was first confirmed by the "twin" version of these objects and further verified by Einstein's Cross. These objects are powered by accretion disks and exhibit the highest redshift in the known universe. For 10 points, name these highly energetic radio sources found at the center of early galaxies.
