For the first time, scientists were able to understand how galactic rotation affects shape. It seems simple, but measuring the three-dimensional shape of the galaxy is a complex process that could not fulfill 90 years.
This is the first time that researchers have traced a clear link between the speed of rotation and the created galactic form.
Galaxies are like a pancake, a sea urchin or a soccer ball. The faster the spiral type rotates, the more circular discs it creates. Looking for help tool SAMI.
SAMI tool on the Anglo-Australian 3.9-meter telescope. Each cable has a hexagon of optical fibers that can look at several different points in the galactic form. Can simultaneously explore 13 galaxies SAMI is incredibly useful because it provides information about the movement of gas and stars inside galaxies. Able to simultaneously study 13 galaxies and operate with scale numbers.
The study examined 845 galaxies, which is three times higher than any previous study. Such a scale helped make a breakthrough. The form depends on past events, like a clash with other formations. Therefore, only one appearance can understand what the object went through and how it all began.
