Ancient Dwarf Galaxy Reconstructed with MilkyWay@home Volunteer Computer
A team of scientists has reconstructed an ancient dwarf galaxy using the MilkyWay@home volunteer computer. The galaxy, known as Gaia-Enceladus, was merged with the Milky Way around 10 billion years ago. The research provides new insights into the formation and evolution of our galaxy.
Introduction
The Milky Way is a barred spiral galaxy that contains billions of stars and planets. It is estimated to be around 13.6 billion years old and has undergone several mergers with other galaxies throughout its history. One of these mergers involved a dwarf galaxy known as Gaia-Enceladus, which occurred around 10 billion years ago.
What is Gaia-Enceladus?
Gaia-Enceladus is a dwarf galaxy that was discovered in 2018 by the European Space Agency's Gaia satellite. It is believed to have been one of the largest satellite galaxies of the Milky Way before it merged with our galaxy. The merger between Gaia-Enceladus and the Milky Way is thought to have played a significant role in shaping the structure and properties of our galaxy.
How was Gaia-Enceladus reconstructed?
The reconstruction of Gaia-Enceladus was made possible by the MilkyWay@home volunteer computer project. This project uses the idle processing power of volunteers' computers to simulate the evolution of our galaxy. The researchers used data from the Gaia satellite to create a model of Gaia-Enceladus and then ran simulations on the MilkyWay@home project to reconstruct its merger with the Milky Way.
What did the reconstruction reveal?
The reconstruction revealed that Gaia-Enceladus was much larger than previously thought, with a mass similar to that of the Large Magellanic Cloud, another satellite galaxy of the Milky Way. The merger between Gaia-Enceladus and the Milky Way was also found to be more violent than previously believed, with the two galaxies colliding at a high velocity. The researchers also found evidence of stars in the Milky Way that were originally part of Gaia-Enceladus, providing further confirmation of the merger.
What are the implications of the research?
The research provides new insights into the formation and evolution of our galaxy. The merger between Gaia-Enceladus and the Milky Way is thought to have played a significant role in shaping the structure and properties of our galaxy, including its halo and thick disk. The findings also have implications for our understanding of other galaxies, as mergers are thought to be a common occurrence in the universe.
Conclusion
The reconstruction of Gaia-Enceladus using the MilkyWay@home volunteer computer project has provided new insights into the formation and evolution of our galaxy. The research has revealed that Gaia-Enceladus was much larger than previously thought and that its merger with the Milky Way was more violent than previously believed. The findings have implications for our understanding of other galaxies and their evolution.
