Morphological Characteristics of Galaxies in Studying Galaxy Evolution via Optimising their Classification

Abstract

"In the beginning, the infinite state of energy released had been the source for the formation of stars, galaxies and other celestial bodies. Ever expanding universe has posed questions on its origin and evolution stages to understand our very existence in this universe and the scientific community is looking for new ways to decode the mysteries in galaxies. As a result multiple sources of modern measurements such as photometric study were employed. Galaxies particularly their physical appearance, spectroscopy, multiwavelength, and their inner arrangement are in the focal point to understand their evolution. Also new studies also reveal inter-merges between them which is commonly termed as “merges” reflected in their shapes and colours. This research takes big data mechanisms in resolving morphological complexities to produce an appropriate classification model, even though considerable interest has been shown in recent years.

Astronomy in the modern day is a semi-structured study based on facts and figures. Generally these figures are unusually big numbers. In modern era astronomy, big data is an inclusion as the 4th paradigm in scientific research due to the reasons that large sky surveys are conducted. Researchers have started to look into the facts with survey images, redshift, multiwavelength, temperature measurements which adds more volume on a daily basis to the existing repositories of data. Exponential growth of information in a small period of time has added both complications as well as new opportunities to zoom in for refining scientific study."
