Example Of Monstrous Galaxies Observed By Aste, Alma And Subaru

Caption

These are example of Monstrous Galaxies. On the left is the image taken at sub-millimeter wavelengths with ASTE. It looks like there is one bright monstrous galaxy. In the center is an image taken at the same sub-millimeter wavelengths, but this time using the new radio telescope facility ALMA. With 60 times better resolution and 10 times better sensitivity, we can see that actually there are 3 monstrous galaxies close together. On the right is the same region photographed in visible light by the Subaru Telescope. We can see that not all of the monstrous galaxies show up in this picture, or at the least that some of them must be very faint.
