Processing Images – M31 Andromeda Galaxy (Part 3 of 3)

To finish up our processing of the Andromeda Galaxy, we process the 4th exposure taken from the Hubble and add it to our current image. This exposure looks specifically at luminescence. Astronomers look at the luminosity of galaxies to study the nucleus of galaxies to see if the luminosity is coming from a supernova or perhaps even one or more black holes.

So we decided to add a luminescence filter to our image processing as we wanted to focus on the nucleus of the Andromeda Galaxy. This exposure is seen on the left.

When using a luminescence exposure, you can change the look and color of the galaxy. However, we decided to keep these as they were and keep the focus on the nucleus of Andromeda.

In the picture below, you will see the image on the left is the same picture from the last post. The image on the right is the final result of our processing of this galaxy and includes the luminescence exposure.

If you look closely at the image on the right, specifically looking at the nucleus in the center of the galaxy, you will see that we now have a little more structure visible to the nucleus.  We believe that this gets us a little closer to showing the true structure of the center of the Andromeda.

The Andromeda nucleus is divided into two seperate nuclei. The nucleus in the true center of the galaxy contains a black hole while the nucleus of to the side does not have a black hole. It is believed that Andromeda has 2 nuclei as one of these is the remanents of a small galaxy which was eaten up by the Andromeda Galaxy.

So the now smaller central dot of light seen in the image on the right may very well be the 2 nuclei sitting side by side.
