In Q-FFF Theory the LONELY CLOUD is known to be possible in the center a a cluster, compressed by the so called dual GABHs ( Galaxy Anchor Black Holes) positioned outsiide and perpendicular to all galaxies. between two or more galaxy GABHs a pressure cooker effect is active to form such clouds. see my image 19, cartoons see: https://vixra.org/pdf/1804.0244v1.pdf
The GABHs black holes are not visible of course.

For the LONELY CLOUD, of Abell 1367, (or UBGs Ultra Diffuse Galaxy) see image of three galaxies with 3x GABHs in a cluster acting as plasma pressure cooker. see the three yellow stars in image below, depicted for the Virgo Cluster as an example.
