In the early days of the universe, our home looked very different from how it does today. Back then, the region in our universe that would eventually become our Milky Way neighborhood was a collection ...

For decades, astronomers have cast galaxy mergers as the universe's ultimate relationship drama: two galaxies collide, chaos erupts, black holes awaken and star formation comes to a screeching halt.

The simulation results show that star formation in dwarf galaxies is closely linked to the supply of cold gas in the CGM. More than 40% to 70% of the galaxy's mass originates from gas inflows, and ...

You can watch how these galaxies coalesced over time and formed the familiar spiral disk we see today, thanks to a new set of ...

At the heart of most large galaxies sits a supermassive black hole. They’re the most massive objects in the universe, ...

Quasars are the brightest objects in the universe and among the most energetic. They outshine entire galaxies of billions of stars. A supermassive black hole lies at the heart of every quasar, but not ...

Ultra-detailed simulations are showing how the first stars lit up the dark Universe and seeded space with elements such as carbon, oxygen, and iron. The MEGATRON project could bridge JWST observations ...

Image: Snapshots of the time evolution of a collision of two spiral galaxies with black holes at their center from a computer simulation. Color indicates temperature and brightness the gas density.

The earliest galaxies are thought to have formed as the gravitational pull of dark matter, which has been impossible to study directly, slowly drew in enough hydrogen and helium to ignite stars. But ...

Cold gas does not look dramatic at first glance. Neither does dust. Yet those two quiet ingredients sit at the center of a new effort to build a far more realistic picture of how galaxies formed. They ...
