The Milky Way is far from alone in its turning point of the Universe . Around our own coltsfoot , astronomers have detected around 60 smaller orbiter beetleweed , the self-aggrandising of them being the Large Magellanic Cloud with 1 percent of the mass of the Milky Way . Astronomers consider many more of these satellite live , based on their late model using glum matter .
As reported in a report to be write inThe Astrophysical Journal , the team used know satellites of the Milky Way to refine their good example and make anticipation about the intergalactic space . The simulation paint a picture that about 100 tiny galaxies are yet to be let out around our coltsfoot .
" We know some thing about dark issue very well – how much dark thing is there , how does it cluster – but all of these statement are certified by say , yes , that is how it behaves on scales larger than the sizing of our local group of galaxy , " conduct source Ethan Nadler , from the Kavli Institute for Particle Astrophysics and Cosmology ( KIPAC ) and Stanford University , say in astatement . " And then the question is , does that form on the smallest scales we can assess ? "
To suffice this question , the team used a advanced galax organization computer simulation . The model is flexible to account for the many thing we do n’t be intimate about dark thing . So far , what we do know is that this substance ( if it really exist ) appears to only interact with gravity , outweighs ordinary matter five - to - one , and keeps galaxies and beetleweed clusters in shape . Using the simulation , the team take care for all the possible practical universes where they could form the Milky Way ’s companions as we see them today .
The key parameter in the simulation was the Large Magellanic Cloud . Last year , astronomers discovered that theMilky Way stole six orbiter galaxiesthat used to belong to the Large Magellanic Cloud . This metre around , the team include in the simulation the hypothesis where that special factor fare into play . The scenario provided insight into the past of the system , suggesting that the Large Magellanic Cloud had a close fundamental interaction with the Milky Way in the last 2 billion years , and furnish the researchers with an idea of how many satellites are still yet to be strike .
It ’s possible that once the work on the next - multiplication Vera C. Rubin Observatory is complete , it could be used to find the undetected satellites of the Milky Way .
