Did I image a black hole in M31?

This is from processing in pixinsight and it is the core after separating the stars and the dust of the galaxy. Tiny void in the center of the colored gas

Thanks

Completely impossible. The SMBH in Andromeda subtends 2e-6 arcseconds. Your image has a scale of 2 arcseconds/pixel. So the central black hole is a millionth of a pixel across. And it's not an active BH, so there's no accretion disk. Hubble can barely image a tiny cluster of stars orbiting the central BH, but can't see the BH itself.

Thank you Chris. Very helpful info.

Subtends 2e-6 arcseconds for the Andromeda SMBH. The scale of your picture is two arcseconds per pixel. The core black hole is one millionth of a pixel in size. Since it is not a dynamic BH, an accretion disk cannot exist. Although Hubble can hardly make out a small star cluster that circles the center BH, the spacecraft cannot see the center BH itself.
