An astronomical radio object is classified as a ROCOS if it possesses (a) an optical image with stellar appearance, which is identified with a radio source, and (b) no emission or absorption features in its optical spectrum, except for those due to galactic interstellar medium, with a signal-to-noise ratio at the level of those observable for quasar candidates.

Radiophysics (also modern writing radio physics [1]) is a branch of physics focused on the theoretical and experimental study of certain kinds of radiation, its emission, propagation and interaction with matter. The term is used in the following major meanings: study of radio waves (the original area of research) study of radiation used in ...
Yashwant Gupta (born 1 November 1962) is an Indian astrophysicist and a professor at the National Centre for Radio Astrophysics (NCRA) of the Tata Institute of Fundamental Research. [1] He is currently a Distinguished Professor and also the Centre Director at NCRA.
The National Centre for Radio Astrophysics of the Tata Institute of Fundamental Research (NCRA-TIFR) is a institute for radio astronomy in India. Research activities at NCRA-TIFR are centered on low frequency radio astronomy, with research in a wide range of areas, including solar physics, pulsars, active galactic nuclei, the interstellar medium, supernova remnants, the Galactic Center, nearby ...

Example of a radio map estimate using STORM, a transformer-based radio map estimator. Signal strength maps quantify signal strength at each location. Formally, a signal strength map can be seen as a function γ ( r ) {\displaystyle \gamma (\mathbf {r} )} that provides a signal strength metric for each location r {\displaystyle \mathbf {r} } .
Lorimer Burst – Observation of the first detected fast radio burst as described by Lorimer in 2006. [1] [failed verification]In radio astronomy, a fast radio burst (FRB) is a transient radio pulse of length ranging from a fraction of a millisecond, for an ultra-fast radio burst, [2] [3] to 3 seconds, [4] caused by some high-energy astrophysical process not yet understood.
