Admire the galaxy's magnetic field with high resolution

A team of scientists led by Max Planck Institute of Astronomy (MPA) has created a map with the highest resolution of magnetic fields of the galaxy ever. The map is made up of 41,000 calculations from 26 different projects. Dr. Tracy Clarke of Naval Research Department said: 'The results of these data are like drawing the whole sky with different angles with the distance of two moons'.

Each map consists of 41,330 separate points representing Faraday's depth calculations along with the value of the magnetic field in a defined space. Polarized light rays from radio sources in the universe were observed to apply Faraday's law. It is these laws that explain the polarizing polarization of the planet. The angle and direction of rotation have been determined, which is where the strength of the magnetic field can be calculated in a certain direction.

Even with a rich source of data, creating a complete sky map is never an easy thing. In fact, creating such a map of MPA experts uses new rules for field information theory (IFT). IFT borrowed the theory of information theory to deal with uncertain things and then put them into the three-dimensional data field of the universe. Scientists have developed an algorithm known as the 'maximum limit domain filter' that can handle inaccurate data.

This algorithm was created to serve special purposes such as creating maps of the southern sky with a limited amount of information. Researchers were forced to interpolate some data between available points. This problem arises when there is a deviation in accuracy between calculations as well as there is no separate calculation (including the most accurate calculation) that becomes essential independence in an isolated environment. In addition, the complexity of the calculations also makes it possible to make even the most minor errors in the data.

In the new map, the red zone tells us a part of the sky at which the magnetic field is directed at the observed satellite while the blue area shows the opposite. In the middle of the map is the center of the universe. It is hoped that in the future, MPA data and techniques may be used for the purpose of magnetic field research outside the galaxy. In addition, the next-generation radio telescope will help enrich the magnetic field on the Milky Way and possibly help us discover the secrets of creation.
