Abstract

4C+35.28, also known as J1215+3448, 1213+350, contains a binary supermassive black hole at separation 290 pc. Very long baseline interferometry images in a range of 1.4 to 43.2 GHz show two compact components. Both objects are supermassive black holes. The binary nature of 4C+35.28 was established by their spectra, variability, and compactness.
