A central objective of chemical and molecular physics is to understand molecules as quantum mechanical systems. The complex internal dynamics of such systems evolve across wide energy and time scales, exhibited by a variety ...
To come into being, galaxies need a steady diet of cold gases to undergo gravitational collapse. The larger the galaxy, the more cold gas it needs to coalesce and to grow.
