Astronomers capture 'dying' distant galaxy losing its fuel to make new stars

Astromers have observed a rare phemen in as y have witnessed a dying galaxy. distant galaxy released almost half of gas that it uses for star formation that might have responsible for a collision with ar galaxy. An international team of astromers from Durham University le research in which y analysed nine billion years from several years past in order to search for evidence that galaxy mergers in early universe could stop star formation and die out eventually. rare observation was recorded by astromers using Atacama Large Millimeter or submillimeter Array of telescopes in Chile. 

According to study published in journal Nature Astromy, light from this dying galaxy, kwn as ID2299, took an estimated nine billion years to reach Earth. Astromers found that galaxy h alrey diminished emitted close to 46 per cent of total cold gas that is used to carry out star formation. "This is first time we have observed a typical massive star-forming galaxy in distant Universe about to 'die' because of a massive cold gas ejection," said Annagrazia Puglisi, le study researcher and postdoctoral research associate from Durham University in UK and Saclay Nuclear Research Centre in France said in a statement. "Our study suggests that gas ejections can be produced by mergers and that winds and tidal tails can appear very similar," said study's co-author and astromer at Saclay Nuclear Research Centre in France, Emanuele Ddi. "This might le us to revise our understanding of how galaxies 'die'," he ded.

"ALMA has shed new light on mechanisms that can halt formation of stars in distant galaxies. Witnessing such a massive disruption event ds an important piece to complex puzzle of galaxy evolution," said Chiara Circosta, study coauthor and researcher. 

Fuel exhausted in nuclear regions

According to research, phemen was caused after diminishing galaxy's collision with ar galaxy that created a separate galaxy kwn as ID2299 without tidal tail. Despite fact that galaxy's bright tails were usually invisible, astromers were able to observe that this new galaxy lacked tidal tail due to  collision. merger led to a large amount of star formation in nuclear regions of newly merged galaxy dubbed ID2299 which led to one of galaxies to starve, thus depleting  fuel needed for new stars to form. For at least several hundred million years, galaxy will be unable to produce stars, which will eventually shred out celestial entity and hamper its development. 'We don't yet kw what exact processes are behind switching off of star formation in massive galaxies," le author at Durham University's Centre for Extragalactic Astromy Annagrazia Puglisi said.
