The universe has a habit of making us feel spectacularly insignificant, but some discoveries take this to an entirely new […] ...

Recent astronomical research indicates that our Earth may be embedded within one of the largest known structures in the ...

Understanding the early universe is a foundational goal in space science. We're driven to understand nature and how it evolved from a super-heated plasma after the Big Bang to the structured cosmos we ...

The Lambda Cold Dark Matter (LCDM) theory suggests that most galaxies are low-mass dwarf galaxies, many of which orbit larger galaxies like the Milky Way. More broadly, the LCDM represents our best ...

Galaxies are far more than the sum of their stars. Long before stars even formed, dark matter clumped up and drew regular matter together with its gravity, providing the invisible scaffolding upon ...

Observations indicate that a continuous supply of gas is needed to maintain observed star formation rates in large, discy galaxies. To fuel star formation, gas must reach the inner regions of such ...

We examine the global H i properties of galaxies in quarter billion particle cosmological simulations using gadget-2, focusing on how galactic outflows impact H i content. We consider four outflow ...
