: CS1 maint: location missing publisher (link)So far, the clumsily long name 'quasi-stellar radio sources' is used to describe these objects. Because the nature of these objects is entirely unknown, it is hard to prepare a short, appropriate nomenclature for them so that their essential properties are obvious from their name. For convenience, the abbreviated form 'quasar' will be used throughout this paper.
Summary: Chinese-American astrophysicist Hong-Yee Chiu (b. 1932) is credited with coining the term "quasar" in 1964.
it is fair to say that the single most influential event contributing to the acceptance of black holes was the 1967 discovery of pulsars by graduate student Jocelyn Bell. The clear evidence of the existence of neutron stars – which had been viewed with much skepticism until then – combined with the presence of a critical mass above which stability cannot be achieved, made the existence of stellar-mass black holes inescapable.
