How well a galaxy dances may be a matter of life or death.
Massive galaxies arise by the time the universe is less than half its current age. Wait four billion more years, and by how much do these galaxies grow? The answer may surprise you.
Galaxy clusters act like cosmic telescopes, magnifying our view of the universe. These exceptionally massive structures allow astronomers to gaze deep into the cosmos and study galaxies during early ages of the universe in fantastic detail. With the completion of the Frontier Fields survey, we can now study a population of magnified, distant galaxies like never before.
Ever tried to see fireworks through the smoke? New results suggest we might be missing some of the action.
What makes a starburst galaxy? Do they have more gas or more efficient star-formation?
What processes will disrupt a cloud of gas passing through the circumgalactic medium?
