Active galactic nuclei (AGN) are supermassive black holes at the centers of galaxies that are accreting material onto their hot circumnuclear disks, releasing the energy in bursts of radiation or as particle jets moving at ...

The supermassive black holes in the centres of many galaxies seem to have a major influence on their evolution. This happens during a phase in which the black hole is consuming the material of the galaxy in which it resides ...

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 ...

In a recently published research, which is part of a broader observational campaign focused on studying massive spiral galaxies, astronomers have investigated molecular lines of carbon monoxide and its isotopologues in NGC ...
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. ...

The sun, like all stars, was born in a giant cold cloud of molecular gas and dust. It may have had dozens or even hundreds of stellar siblings – a star cluster – but these early companions are now scattered throughout ...
