New Study on 3-D Distribution of Molecular and Atomic Hydrogen in Andromeda Galaxy

A researcher from Raman Research Institute (RRI), Bengaluru, has estimated the three-dimensional distribution of molecular and atomic hydrogen in the Andromeda galaxy. The findings can lead to clues to the star formation processes and the evolution of galaxies.

Context of the Research

  • Galaxies - like the Milky Way - consist of discs containing stars, molecular and atomic hydrogen, and helium. The molecular hydrogen, under the force of gravity, collapses on itself in distinct pockets, forming stars. Its temperature is observed to be low (-2630C) and thickness is about 60 to 240 light-years. The atomic hydrogen extends both above and below ....
