Wild 'teenage'-galaxies booming with star births

Scientists from the Dark Cosmology Centre have been studying distant galaxies which are among the most active star-forming galaxies in the Universe. They form around 1,000 new stars a year – a 1,000 times more than our own galaxy, the Milky Way. The findings have been published in Monthly Notices of the Royal Astronomical Society.

Together with researchers from the Royal Observatory, Edinburgh and Durham University in England, he has studied the distant galaxies using the Expanded Very Large Array, which is an astronomical observatory in New Mexico, USA.

"We have measured CO, that is to say carbon monoxide, which is one of the most common molecules in the Universe, after the hydrogen molecule, H2. Using the measurements we have calculated how much gas there is in the galaxy and it turns out there are extremely large amounts of gas in these galaxies ", explains Thomas R. Greve.
