Ancient blast comes to light

Article Abstract:

Light from the oldest and farthest stellar explosion was emitted when the Universe was in its formative stage and knowledge of the phenomenon provides a close-up view of how and when stars formed, and how they affect the primordial gas around them. It is understood that the most distant objects that can be identified spectroscopically are not just galaxies but also individual stars.

Recombination cool and fast

Article Abstract:

The H3(super +) ion assumes an important role in astrophysics as the first link in a chain of chemical reactions in interstellar clouds through which most of the molecules found in interstellar space form. Interstellar clouds were seen to contain much more H3(super +) than expected, bringing the persistent enigma of its recombination rate back to the fore.

Unity among black holes

Article Abstract:

The observations of X-ray emissions from galactic black holes (GBH) having masses between 5 and 20 times that of the Sun and active galactic nuclei (AGN) weighing many millions of solar masses is presented. The findings indicate that despite the huge disparity in their masses the physical mechanisms that power these two classes of object are same.
