Where is the zone of avoidance

While the galaxy was easily recovered in the second radio search, and the optical images showed a faint clump, the centers of the two did not appear to line up. The visual and radio components seemed not to overlap almost at all. A portion of the reason for this is that the team was unable to image the faint galaxy out to its full extent before the contamination from our own galaxy overwhelmed the signal.

As such, the two likely overlap more than is indicated by the study, but this would still indicate that the distribution of hydrogen gas within it is severely lopsided. However, such clouds of gas tend to travel in packs and no others are known in the area, making this possibility unlikely.

If the object is a galaxy, it is likely a blue dwarf galaxy with some 10 million solar masses. The team expects that, while the galaxy is relatively nearby, this galaxy is not likely to bea member of the local group because, were it that close, it would be unprecedentedly small. The group comprises more than 30 galaxies including dwarf galaxies , with its gravitational center located somewhere between the Milky Way and the Andromeda Galaxy.

The group is estimated to have a total mass of 1. The group itself is part of the Virgo Supercluster i. All Rights Reserved.
