Currently, our scientists are involved in exploring the facts of a relic galaxy which is believed to be in the frozen state for a span of about ten billion years. Let us focus on relic galaxy concept to understand the current study in a better way. There are thousands of massive galaxies spread across space. It is believed that one in those thousand massive galaxies receives the honour of being called as the relic galaxy. This trend is being followed since the early days of universal creation.
Relic Galaxies are known to encircle their original properties and keep them intact. These properties signify the relic galaxies since their early days of formation. Unfortunately, these relic galaxies are in an unproductive state of arrested development.
The telltale sign of the unproductive state of Relic Galaxy lies in ancient star clusters. These old stars clusters are seen to be swarming around these Relic Galaxies since their formational days.
The massive galaxies are known to possess both the metal-poor star and metal-rich stars. The metal-poor stars appear as red globular clusters, while the metal-rich stars appear as red globular clusters. It is being said that the red globular clusters trace their birth with the early days of universal creation. In place of this, the blue globular clusters were formed later. The delay in the formation of blue globular cluster accounts to the swallowing of smaller satellites by the central galaxy.
Interestingly, the Relic Galaxy do not exhibit the presence of these blue globular clusters. The most significant supporting evidence of that represents this type of Relic Galaxy is the NGC 1277. NGC 1277 is entirely devoid of the blue globular stars clusters.
Thus, one can say that the red globular clusters represent the most substantial evidence that the galaxies have crossed the frontiers of star-making business. The absence of the blue clusters of stars suggests its stagnancy by gobbling up the galaxies in its proximity.
