kuâsâr-e maqzé ciré
Fr.: quasar dont l'émission de cœur domine
A → radio-loud quasar in which the central source is enhanced by → relativistic beaming and characterized by a → flat → spectrum. It has been conjectured that this phenomenon is an → orientation effect. If a radio-loud quasar is seen along its → jet, it will appear as a core-dominated source. See also → lobe-dominated quasar.
To have control, authority, or influence;
to be the most important or conspicuous person or thing.
From L. dominatus, p.p. of dominari "to rule, dominate, govern," from dominus, → domain.
Ciridan, from ciré "dominant; powerful; victorious," Mid.Pers. cêr "victorious, brave," Av. cirya- "able, brave."
Fr.: série dominée
kuasâr-e lap ciré
Fr.: quasar à lobes dominants
A → radio-loud quasar in which the lobes dominate the whole emission. It has been conjectured that this phenomenon is an → orientation effect. If the → jet is close to the plane of the sky, the lobes will dominate. See also → core-dominated quasar.
Fr.: Univers dominé par la matière
A Universe in which the matter energy density (Ωm ≈ 1) provides most of the total energy density. According to the → Big Bang model, in the early history of the → Universe a → radiation-dominated phase preceded the matter-dominated phase. This phase is characterized by R/R0 ∝ t2/3, where R is the → cosmic scale factor and t is time.
Fr.: Univers dominé par le rayonnement
An early epoch in the history of the → Universe when the radiation → density parameter was Ωr≈ 1, while other density parameters had negligible contributions. A radiation-dominated Universe is characterized by R/R0 ∝ t1/2, where R is the → cosmic scale factor and t is time. According to the → Big Bang model, the radiation-dominated phase was followed by the → matter-dominated phase.
