Bulgarian discovered a collision of galaxies
The Milky way collided with another galaxy 2 billion years ago and might still be “shaking” from the hit; this theory was shown by a computer model, work of the Bulgarian scientist Ivan Minchev.
Some groups of stars closer to our Solar system are moving at an unusually high spped in comparison with others in the galactic disk.
Ivan Minchev from the University of Strasbourg, France, notes that the model and speed of movement can be explained with the collision that occured so long ago.
Ivan Minchev graduated in the fields of Physics and Astronomy. He developed a computer simulation of the allocation of speeds of billions of stars.
“This is much more than the stars included in earlier models”, says the co-author of the simulation Alice Quillen from the University of Rochester in New York.
