Hypervelocity stars are rare stellar objects travelling at velocities exceeding the local Galactic escape speed, providing unique tracers of dynamic interactions in galactic nuclei, star clusters and ...

Star clusters arise within the densest cores of molecular clouds, where gravity drives the collapse of gas and dust to form stars nearly simultaneously. Their formation is regulated by the complex ...

If you want to pinpoint your place in the universe, start with your cosmic address. You live on Earth->Solar System->Milky Way Galaxy->Local Cluster->Virgo Cluster->Virgo Supercluster->Laniakea.

When studying local galaxy cluster Abell 3667, Anthony Englert GS, a Ph.D. candidate in physics, noticed something unique. Connecting the brightest galaxies in two small clusters within Abell 3667 was ...

Galactic Globular clusters (GCs) are among the oldest bound stellar systems in the Universe, hosting high-density populations ...

Using the Anglo-Australian Telescope (AAT), astronomers have observed a nearby galactic globular cluster known as NGC 6569. Results of the observational campaign, published December 22 on the arXiv ...
