Radio object with continuous optical spectrum
Radio Objects with Continuous Optical Spectra, (abbr. ROCOS, also referred to as ROCOSes) is a group of about 80 astrophysical objects characterized by optical spectra anomalously devoid of emission or absorption features, which makes it impossible to determine their distances and locations in relation to our galaxy. They are considered to be a subclass of blazars, and are similar in their spectral characteristics to DC-dwarfs and single stellar-mass black holes.
==Discovery and study==
Radio Objects with Continuous Optical Spectra, or ROCOSes, were discovered in the 1970s.〔 Among the discoverers was a group of Soviet astrophysicists, who studied them at the Crimean Astrophysical Observatory (Ukraine) and the Special Astrophysical Observatory of the Russian Academy of Science (Russia), using the former's 2.6-meter optical telescope and the latter's 6-meter optical telescope, along with a 1000-channel photon counter and photometers.〔〔〔 The group published their findings in a series of articles in the Russian scientific journals ''Astronomy Letters'' and ''Astronomy Reports''.〔〔
