These effects also influence the apparent angular size of celestial objects, which, for objects at high redshift, varies with distance and redshift in a non-intuitive manner. This article presents the derivation of the relation between angular diameter distance and redshift within specific models of a flat universe</dc:description><dc:description xml:lang="sl">Zaradi širjenja vesolja se razdalja med zelo oddaljenimi nebesnimi telesi s časom povečuje, zato je treba pri merjenju razdalj na velikih skalah upoštevati kozmološke učinke. Slednji vplivajo tudi na navidezno kotno velikost nebesnih teles, ki se z razdaljo in rdečim premikom za zelo oddaljena telesa nepričakovano spreminja. V članku je predstavljena izpeljava zveze med razdaljo kotne velikosti in rdečim premikom v posebnih modelih ravnega vesolja</dc:description><edm:type>TEXT</edm:type><dc:type xml:lang="sl">znanstveno časopisje</dc:type><dc:type xml:lang="en">journals</dc:type><dc:type rdf:resource="http://www.wikidata.org/entity/Q361785" /></edm:ProvidedCHO><ore:Aggregation rdf:about="http://www.dlib.si/?URN=URN:NBN:SI:doc-6FFJBL8I"><edm:aggregatedCHO rdf:resource="URN:NBN:SI:doc-6FFJBL8I" /><edm:isShownBy rdf:resource="http://www.dlib.si/stream/URN:NBN:SI:doc-6FFJBL8I/ae2515df-2682-4b84-9790-2a0c1fe5be4b/PDF" /><edm:rights rdf:resource="http://creativecommons.org/licenses/by-sa/4.0/" /><edm:provider>Slovenian National E-content Aggregator</edm:provider><edm:intermediateProvider xml:lang="en">National and University Library of Slovenia</edm:intermediateProvider><edm:dataProvider xml:lang="sl">Univerza v Ljubljani, Fakulteta za matematiko in fiziko</edm:dataProvider><edm:object rdf:resource="http://www.dlib.si/streamdb/URN:NBN:SI:doc-6FFJBL8I/maxi/edm" /><edm:isShownAt rdf:resource="http://www.dlib.si/details/URN:NBN:SI:doc-6FFJBL8I" /></ore:Aggregation></rdf:RDF>
