HOW CAN SUPERNOVAE TYPE 1A BE USED AS DISTANCE INDICATORS TO REFINE COSMOLOGICAL MODELS

This research paper explores the use of Type 1a supernovae as distance indicators to refine cosmological models. Type 1a supernovae possess a consistent brightness, making them reliable standard candles for measuring distances in space. By analyzing their luminosity and comparing it to their observed brightness, scientists gain insights into the expansion or acceleration rate of the universe (Reiss A, 2000 ‘The case for an accelerating universe from supernovae' Astronomical society of the Pacific). The study of Type 1a smashes has played a vital part in broadening our understanding of cosmological dynamics and refining propositions. Also, this paper discusses the disquisition of the Lambda- CDM model as an abelian frame for comprehending the expansion of the universe. Type Ia supernovae can only take place under specific conditions which is why they can be used as reliable standard candles. The research highlights the significance of Type 1a supernovae in refining cosmological models and enhancing our knowledge of the universe's dynamics.
