At comparable masses of the galaxy is about one hundred times fainter than the milky Way.
Astrophysics from the USA and Canada found a dark double of the milky Way — the Dragonfly 44. The full study is available on the website arXiv.org.
At comparable masses of the galaxy is about one hundred times fainter than the milky Way. This means that its center may be a quasar, which directs the gas-dust matter necessary for the formation of stars away from the galaxy.
The rotation speed of the Dragonfly 44 is currently small, however, as scientists believe, previously it was higher. This slowdown of the movement of scientists associated with its collisions with other galaxies.
Galaxy Dragonfly 44 located in the cluster of coma Berenices at a distance of 99 MPC from the Sun. The method of Doppler spectroscopy, astrophysicists have determined the relative speed of movement of stars in it, which amounted to 47 kilometers per second. Investigated galaxy a trillion times heavier than the Sun and contains 90 of globular star clusters.
For the detection of Dragonfly 44 it took 33.5 hours of observations at the Keck Observatory (Hawaii, USA). For galaxy had to watch such a long time due to its low brightness.
