We present a detailed examination of the brown dwarf multiples 2MASS J08503593+1057156 and
2MASS J17281150+3948593, both suspected of harboring components that straddle the L dwarf/T

The transition from quasar radio-loud to radio-quiet state in the framework of the black hole scalability hypothesis
Cosmology and Extragalactic Astrophysics (astro-ph.CO)

There are several lines of evidence that active galactic nuclei (AGN) can be regarded as scaled-up X-ray binaries (XRB). The timescales of the evolutionary phenomena in these two classes are proportio...
Investigation of the Effects of Expectation Values for Radii on the Determination of Transition Probabilities using WBEPM Theory
Neutral nitrogen atomic data transition probabilities WBEPM theory
2010/9/15
Transition probabilities for some excited s–p and p–s transition arrays of neutral nitrogen have been calculated using the weakest bound electron potential model theory (WBEPMT) for the investigation ...
