Located in the Grus Constellation, are all 4 spiral galaxies.
Further up we have NGC 7552, the smallest of the three below is ngc 7590, with its mate next to ngc 7599. The most central and most studied of them is NGC 7582.
NGC 7582 is a type 2 Seyfert galaxy, such a classification is due to the fact that the galaxy has an extremely bright supermassive central black hole very similar to a quasar (most energetic objects in the universe). The black hole of NGC7582 is about 10 million times the mass of our sun.
