Galaxies as 'cosmic cauldrons'

Star formation within interstellar clouds of gas and dust, so-called molecular clouds, proceeds very rapidly yet highly inefficiently. Most of the gas is dispersed by stellar radiation, revealing galaxies to be highly dynamic ...

Star formation in galactic centers

Stars form from the gas and dust in molecular clouds via a series of complex processes that are currently only partly understood, and the evolution of these clouds drives the evolution of the stellar populations in the universe. ...

Image: Cloudlets swarm around our local supermassive black hole

This image from the Atacama Large Millimeter/submillimeter Array (ALMA) shows the area surrounding Sagittarius A*, the supermassive black hole that lurks at the centre of the Milky Way—highlighted here with a small circle. ...

Image: Herschel's view of the galactic centre

An odd-shaped formation of gas and dust at the centre of the Milky Way, captured by the far-infrared cameras on board ESA's Herschel space observatory. The nearly continuous strip of dense and cold clumps of material forms ...

Magnetized inflow accreting to center of Milky Way galaxy

Are magnetic fields an important guiding force for gas accreting to a supermassive black hole (SMBH) like the one that our Milky Way galaxy hosts? The role of magnetic fields in gas accretion is little understood, and trying ...
