The European Southern Observatory (ESO) reports that researchers have made an important discovery that sheds light on the mechanism of fluorine production in the universe.
Scientists from the University of Hertfordshire in the UK have recorded the presence of fluorine (as part of hydrogen fluoride) in large clouds of gas in the distant galaxy NGP-190387, which is more than 12 billion light years away. It is a star-forming galaxy.
" Since stars eject elements formed in their cores outward when their lives come to an end, this finding means that stars that formed fluorine must have traveled their way and died very quickly ," notes ESO.
Researchers believe that the source of fluorine in the observed galaxy is the Wolf-Rayet stars, very massive luminaries, whose life span only a few million years.
“ The discovery of fluorine in NGP-190387 is one of the first cases of fluorine detection outside the Milky Way and neighboring galaxies. Previously, astronomers found this element in distant quasars. But never before has fluorine been observed in a galaxy with active star formation at such an early stage in the history of the Universe, ”the publication says.
It should be noted that the observations were carried out using the Atacama Large Millimeter / Submillimeter Array (ALMA).
