The early universe remain to be a inscrutable frontier , with researchers turn over ever further into the first few billion years of the cosmos . A new 3D mapping of the distribution of galax during this menstruation was presented today at theEuropean Week of Astronomy and Space Sciencein Liverpool .
The new study produce one of the largest mathematical function of the infant macrocosm , taking shot of galaxies at 16 dissimilar epochs 11 - 13 billion years ago . That ’s between 20 and 7 percent of the current age of the universe . In this function , the external team of researchers get word almost 4,000 young early Galax urceolata , some of which were the seed that eventually evolved into helical Galax urceolata like the Milky Way .
“ These early galaxies seem to have gone through many more ' bursts ' when they formed stars , instead of forming them at a relatively unshakable rate like our own galaxy , " team leader Dr David Sobral , from Lancaster University , said in astatement . " Additionally , they seem to have a population of young star that is hot , bluish and more metal - inadequate than those we see today . "
The map was created thanks to telescope in Hawaii and the Canary Islands . The team used 16 unlike filter that correspond to the 16 different epochs . Due to the expansion of the population , the lighting of coltsfoot is shift towards the red . The further away they are , the redder those coltsfoot appear . The filters focus on specific wavelengths , thus catch galaxy at specific epochs .
The map is a young important tool in our understanding of galaxy evolution . During those early ( billion ) years , galaxies began to grow to their present - day size and the rate of virtuoso formation was hit its all - meter high . We can take a lot about modern galaxies by learn those .
“ The mass of the distant galaxies we witness are only about 3,000 light - years across in size of it , while our whitish Way is about 30 times large . Their compactness likely explains many of their exciting strong-arm properties that were unwashed in the early Universe , ” co - generator Ana Paulino - Afonso , a PhD student in Lancaster and Lisbon , added . “ Some of these galaxies should have evolved to become like our own and thus we are seeing what our coltsfoot may have looked like 11 to 13 billion eld ago . ”
The inquiry is published in two paper in theMonthly Notices of the Royal Astronomical Society , and the map is publicly uncommitted to use .
