DECam and Gemini South discover three tiny 'stellar-ghost-town' galaxies

'Cosmic Ghost Towns' Could Hold Clues the Mysteries of Galactic Structure - The Debrief

University of Arizona Steward Observatory astronomers have discovered “cosmic ghost towns” that were halted in their development by cosmic forces billions of years ago. The “ghost towns,” named Sculptor A, B, and C, consist of three faint and ultra-faint galaxies about 6.5 million light-years from Earth. Despite their barren nature, these desolate regions of space may hold surprisingly important answers about the structure of our modern galaxy. …

Newly Discovered Stellar "Ghost Town” Galaxies Were Strangled A Long Time Ago

It is not clear how their star formation was stifled in the early universe.

Three tiny 'stellar-ghost-town' galaxies discovered

By combining data from the DESI Legacy Imaging Surveys and the Gemini South telescope, astronomers have investigated three ultra-faint dwarf galaxies that reside in a region of space isolated from the environmental influence of larger objects. The galaxies, located in the direction of NGC 300, were found to contain only very old stars, supporting the theory that events in the early Universe cut star formation short in the smallest galaxies.

Silent Ghost Towns of Space: Why Some Galaxies Stopped Evolving

The Silent Echo of Ghost Town Galaxies: What Their Quiescence Reveals About the Universe Welcome to FreeAstroScience, where we simplify the vast complexities of the cosmos. Have you ever paused to think about galaxies that stopped evolving eons ago, their stellar lives frozen in time? These so-called “ghost town” galaxies are like relics, offering profound insights into the early universe. Today, let’s journey together to explore three newly dis…

Astronomy, always in search of the deepest mysteries of the cosmos, has taken a significant new step with the discovery of three ultra-weak dwarf galaxies. This breakthrough, the result of collaboration between powerful telescopes located in Chile and an international team of scientists, sheds light on the events that occurred in the primitive Universe [...]
