An alternative model for pulsars and spiral galaxies
...black hole accretion disk and jet eruption in deep space. Current paradigms The cores of pulsars and spiral galaxies, although of significantly different masses, are generally assumed to consist of a single central object. In the case of pulsars, the...

Mini-spiral galaxies may transform how dark matter is perceived
...matter and dark energy. Mini-spiral galaxies are as the name suggests - spiral galaxies that look similar to our ...new kind of physics," continues Salucci. "Even in the largest spiral galaxies we find effects similar to the ones we observed, but they ...

Astronomers detect a rare type of object known as a spiral DRAGN
...be the case. However in recent years, a handful of DRAGNs have been found in spiral galaxies and this is somewhat puzzling for those studying galaxy evolution. Spiral galaxies cannot undergo a major merger without evolving into another structure, and...

Rotation in the Universe
... the subject, you’ll know that the most frequent references to rotation in cosmology textbooks are to the motion of spiral galaxies. It has been recognised for some time that these assemblages of stars have an awful lot of angular momentum...

First-ever photo proof of powerful jet emerging from colliding galaxies
... light. Furthermore, scientists had previously discovered that these jets could be found in elliptical-shaped galaxies, which can be formed in the merging of two spiral galaxies. Now, they have an image showing the formation of a jet from two younger...

New study challenges the assumption that the Universe doesn't spin
... rotating. But now, a new study on the analysis of more than 200,000 spiral galaxies, contradicts this previously held assumption. Spiral galaxies are a unique astronomical objects because their visual appearance depends on the observer's perspective...
