Methanol maser emission

found in neighboring galaxy

Methanol maser emission

With the help of the ATCA telescope, we managed to detect methanol emissions in the neighboring galaxy NGC 4945. Usually, methanol maser lines are found in areas with intensive formation of massive stars. In our galaxy there are a lot of them, because they are captured in 1200 sources.

Divided into two classes: I and II. Class I is based on the contact of gas with molecular clouds. But the second group is associated with young stars.

Methanol emission at 36.2 GHz and 7 mm continual emission with background 2MASS

Galaxy NGC 4945 is 12 million light-years away. It belongs to the spiral type with a jumper and is located on the territory of Centauri. The researchers recorded the emission of methanol transition 36.2 GHz and 7-mm continuum radiation in the direction of the galaxy. The first observations were made in 2015 in the south-eastern galactic territory. The last radiation width reached only 10 km ⋅ s -1 and could be associated with a molecular influx. The brightness of a particular case is five times higher than class I.

Scientists hope that subsequent reviews of such phenomena will help improve the understanding of the star formation process.
