Dwarf Galaxies behind Formation of Large Proportion of Universe’s Stars – Maine News

A new study by researchers using NASA’s Hubble Space Telescope has put a decade-long investigation to rest that whether or not there is a link between a galaxy mass and its star-forming activity.

The novel study has claimed that dwarf galaxies are behind the formation of a significant portion of the universe’s stars. The study is one of a kind.

Lead author Hakim Atek of the Ecole Polytechnique Federale de Lausanne (EPFL), Switzerland, said they used to suspect that such kind of galaxies have hand in the early wave of star formation. But it is however, now that they have been able to measure the effect they actually had. They appear to have had a surprisingly huge role to play, said Atek.

Credit for the same shall go to the infrared features of WFC3. These capabilities have led astronomers to calculate the level at which the low-mass dwarf galaxies have contributed to stars present in our universe.

Co-author Jean-Paul Kneib from EPFL was of the view that these galaxies have been forming stars at such a high pace that they can double the mass of stars in just 150 million-years.

Dwarf galaxies are not like large galaxies as they take small amount of space. But their features are quite unique as they are quite dense and can lead to surprising number of stars despite taking up such a small amount of space.

‘Starburst’ dwarf galaxies were especially pointed out by researchers to be having the potential of pumping out a lot many stars in such a small amount of time. As Kneib, majority of the galaxies are able to double their mass in one to three billion years.
