Abstract

Gravitacijski su valovi putujuće deformacije gravitacijskog polja koje nose energiju. Iako je njihovo postojanje predviđeno još početkom 20. stoljeća, prvo direktno opažanje ostvareno je tek stotinu godina kasnije unutar međunarodne kolaboracije LIGO. U ovom je radu dan pregled teorijskih tretmana gravitacijskog zračenja u kontekstu linearizirane opće teorije relativnosti. Osim toga, uveden je problem definicije mase koji proizlazi iz Einsteinovog principa ekvivalencije te su predstavljeni razni analitički pristupi koji pokušavaju dati adekvatne definicije. Budući da su potpuno općenite definicije i dalje otvoren problem, promatranje je ograničeno na asimptotski ravne sustave

Abstract (english)

Gravitational waves are traveling displacements of the gravitational field that carry energy. Although their existence was predicted as early as the beginning of the 20th century, the first direct observation was made only a hundred years later within the international LIGO collaboration. This thesis provides an overview of theoretical treatments of gravitational radiation in the context of the linearized general theory of relativity. In addition, the problem of defining mass, which arises from Einstein’s principle of equivalence, is introduced, and various analytical approaches attempting to provide adequate definitions are presented. Since fully general definitions remain an open problem, the discussion is limited to asymptotically flat spacetimes.
