Abstract Galaxy rotation curves are considered to be convincing evidence for dark matter or some dynamically equivalent alternative mechanism. Starting only from the rotation curve data, we present a model independent approach of testing a general hy

Abstract Parametrizations of equation of state parameter as a function of the scale factor or redshift are frequently used in dark energy modeling. The question investigated in this paper is if parametrizations proposed in the literature are compatib

The paper brings a novel approach to unification of dark matter and dark energy in terms of a cosmic fluid. A model is introduced in which the cosmic fluid speed of sound squared is defined as a function of its equation of state (EoS) parameter. It i

Purely kinetic k-essence models have been shown in the literature to be a field theory equivalent of barotropic fluid models of dark energy or dark matter–dark energy unification. In the modeling framework where the speed of sound squared of a baro

The formalism of dark energy based on modeling speed of sound as a function of equation of state parameter is elaborated. A specific model which allows detailed study of cosmological constant boundary crossing is introduced and analytical solutions f

Novi i apstraktni koncepti u obrazovnom se procesu puno lakše usvajaju ako ih se poveže s prethodno poznatim pojavama i realnim, stvarnoživotnim demonstracijama koje nisu samo apstraktne animacije na ekranu. Temperatura je veličina čije je obja
