This was confirmed when . and .. showed that the fluctuations were due to an intense emitting region less than eight minutes of arc in extent

Pursuing the Shadows of Consciousness,axies and, most recently, with intergalactic matter. While all of these studies, in the past, have gone their individual ways, it is now not only appropriate but necessary to consider the interrelations and the transitions between the various forms of the large scale aggregations of matter. These ag

The remaining objects, numbering hundreds of millions within the reach of the 200-inch telescope, are stellar systems distributed through extragalactic space. These systems, which, because of th

In discussing these questions, the operational point of view will be adopted: the distance of a galaxy must be found by an instrumental procedure wh

https://doi.org/10.1007/978-3-030-19651-6A correct kinematical description of the galaxy is a necessary first step before it is profitable to develop detailed dynamical theories. For example, if the motions in the galaxy are inward along the spiral arms the resulting dynamical theory will differ from one that explains circular motions.
