The team of international scientists, using the WM cake observation on Mauna Kaa in Hawaii, revealed an unusual space education-clerk Galaxy FCC 224 without a almost dark substance. This galaxy is located at the foot of Fordax’s star clusters with approximately 60-65 million light years from Earth. Published in İş Magazine Journal of Astrophysics (Astrojournal).
The discovery undermines the foundations of a modern cosmological model in which dark matter is considered an important component in the formation of galaxies. Before that, such objects were found in only one area – NGC 1052 galaxy galaxy. New data show that galaxies with a lack of dark matter may be more common than previously taken into consideration.
“FCC 224 contains many bright ball clusters, but also does not contain almost dark matter – at least in its inner areas,” Maria Louise Buzz of the University of Swinburn and the European Southern Observatory said. “None of the existing models of galactic formation can explain its origin.”
To examine the Galaxy device, the researchers used KCWI highly predictable spectroscopic equipment installed in cake telescope. This made it possible to measure the internal movements and savings of the stars of the FCC 224. The data obtained showed an extraordinary low -speed distribution, a characteristic sign of the lack of dark matter.
“Thanks to the high spectral resolution of KCWI, we were able to make the right measurements that confirm the abnormally small effect of dark matter,” Buzza said.
A possible explanation is a galactic “bullet effect”
One of the hypotheses suggests that the FCC 224 can lose the dark matter as a result of another object that separates the dark and ordinary substance and the so-called model of the “lead dwarf galaxy ((bullet-dwarf). However, it requires more observation.
Astronomers are planning to expand the search for other similar galaxies with the help of new sky investigations.
