We investigate the properties of features seen within superluminal sources often referred to as components. Our result indicates a fairly strong correlation of
Carbon stars are excellent kinematic tracers of galaxies and can serve as a viable standard candle,so it is worthwhile to automatically search for them in a lar
This paper deals with the general class of Bianchi cosmological models with bulk viscosity and particle creation described by full causal thermodynamics in Bran
Cosmic opacity and its spatial distribution have been constrained with a model independent method. The average opacity of the universe is not zero, but can be z
Here we present research on an ultra-luminous X-ray source(ULX) candidate 2XMM J140229.91+542118.8. The X-ray light curves of this ULX candidate in M101 exhibit
