Dark matter is a powerful cosmological model, but it isn’t without its problems. In addition to our inability to detect dark matter particles, one issue deals with the number of dwarf galaxies surrounding the Milky Way. According to the most popular models of dark matter, galaxies should be surrounded by clumps of dark matter within their dark matter halo. Since regular matter tends to gather around dark matter, that means the Milky Way should be surrounded by dwarf galaxies.
We have detected a few of them. They are known as Almost Dark Galaxies , and they are particularly dim. We haven’t found enough of them to match the cold dark matter model, but we do keep finding them, as a recent study shows. It describes a newly found dwarf galaxy known as Nube. It was found just by chance in images gathered by the IAC Stripe82 Legacy Project. It is so dim that it doesn’t appear in the Sloan Deep Sky Survey , which is a bit surprising.
It was only through a bit of luck that we found this dark matter galaxy. Given its size, it’s quite likely that other dwarf galaxies are lurking in our celestial neighborhood, if we can only find them. But surprisingly, while galaxies such as these support the dark matter cosmological model, this particular galaxy doesn’t match the profile of the most popular variant known as cold dark matter. Instead, it best fits a version known as fuzzy dark matter.
So we must keep looking for more of these galaxies. The answers to our dark matter questions are surely there, gathered in the dark.
