uranologist have discovered a new class of stellar system of rules . live as blue blobs , these collections are fertile in blasphemous genius and are the size of tiny dwarf galaxies – although , unlike those , they do n’t appear to be very confining to any boastful galaxy .
That ’s not all – the galaxy incline to lack older stars which intimate that they are very untried organisation , but they also miss atomic gas . give the vernal eld of the stars and lack of atomic gas , it stand for that these blobs misplace some of their gas very recently .
One explanation favored by the researcher is that they did a cosmic abdomen flop ( technically make love as read/write memory pressure stripping ) . The findings can be read in a newspaper useable on theArXiv .
" This is like if you belly flop into a swim pool , " conduct generator Michael Jones , a postdoctoral fellow in the University of Arizona Steward Observatory said in astatement . " When a galaxy belly flops into a bunch that is full of hot gas , then its gas gets forced out behind it . That ’s the mechanism that we think we ’re seeing here to create these object . ”
The inquiry suggests that these systems are moving very fast , logical with the observations that they are isolated from larger wandflower , and they have lost most of their atomic gas while still holding onto their molecular gas . The findings were demonstrate at the 240th get together of the American Astronomical Society , which take position last hebdomad in California .
The squad did not set out to notice weird congregations of stars . Their project looked at accelerator pedal clouds in the locality of the Milky Way in the Leslie Townes Hope of finding new dwarf galaxies there , and was followed up by finding of wiz associated with these accelerator clouds . While many of these cloud are plausibly still near our galaxy , the first mathematical group of stars pick out within one of these ended up being in the Virgo cluster . Definitely not next to the Milky Way .
" It ’s a lesson in the unexpected , " Jones said . " When you ’re bet for things , you ’re not inevitably going to find the matter you ’re looking for , but you might find something else very interesting . "
Ram pressure stripping is think to be an significant operation in the organic evolution of galaxy , as it can touch on galaxies entering into clustering following cluster collisions and other processes .
" We remember that this belly flopping process changes a lot of spiral galax into oviform extragalactic nebula on some point , so discover more about the general process teaches us more about galaxy formation . "
