Ghosts of Spiral Arms Past
A study of star clusters in the Milky Way has uncovered a peculiar trend in the way they are arranged.
Does an AGN help or hurt star formation?
A Seyfert 2 galaxy’s energetic nucleus creates impressive twin outflows, but how are they affecting its star formation?
Seeking the Circumgalactic Medium with Dragonfly
The circumgalactic and intergalactic media may contain the majority of baryonic matter in the universe, but their low density makes them extremely faint. Can an instrument designed to image low surface brightness objects help shed light on these ghostly structures?
Darwin’s Theory of Evolution, but make it planets
Can exoplanetary systems remain intact in dense stellar environments, or are their exoplanets destined to be flung into the far reaches of space? N-body simulations hint at characteristics that lead to a higher likelihood of survival.
Reading the Epic of Reionization
Observations of dim galaxies lensed by foreground clusters provides a way of measuring the progression of reionization.
