Researchers provide new evidence of concourse of Milky Way

Researchers at Ohio State University have provided new evidence on the time taken by the early Milky Way to come together and its merger with a key satellite galaxy.

The new study and its results were published by the Journal Nature Astronomy. Researchers involved in the study used new methods to identify the most precise period for a sample of about a hundred red stars in the galaxy.

With new methods and data, the researchers successfully showed what was happening during the merger of the Milky Way with an orbiting satellite galaxy about 10 billion years ago.

“Our evidence suggests that when the merger occurred, the Milky Way had already formed a large population of its own stars,” Fiorenzo Vincenzo, co-author of the study and a fellow in The Ohio State University`s Center for Cosmology and Astroparticle Physics, said.

“The merging event with Gaia-Enceladus is thought to be one of the most important in the Milky Way`s history, shaping how we observe it today,” Josefina Montalban, associated with the School of Physics and Astronomy at the University of Birmingham in the UK, said.
