New Treasure Trove of Globular Clusters holds Clues about Galaxy Evolution

Centaurus A is an elliptical galaxy located about 13 million light-years from Earth. This color composite image reveals the lobes and jets emanating from the active galaxy’s central black hole.ESO/WFI (Optical); MPIfR/ESO/APEX/A.Weiss et al. (Submillimetre); NASA/CXC/CfA/R.Kraft et al. (X-ray)

Using observations of Centaurus A, a nearby elliptical galaxy, obtained with the Gaia space telescope and ground-based instruments under the PISCeS survey, a team of astronomers presents an unprecedented number of globular cluster candidates in the outer regions of the galaxy. The findings provide astronomers with an even more detailed picture of galactic architecture and history of collisions and mergers.

A survey completed using a combination of ground and space-based telescopes yielded a ...
