  • Simulations of structure formation in the Universe predict that galaxies are embedded in a ‘cosmic web’, where most baryons reside as rarefied and highly ionized gas. This material has been studied for decades in absorption against background sources, but the sparseness of these inherently one-dimensional probes preclude direct constraints on the three-dimensional morphology of the underlying web. Here we report observations of a cosmic web filament in Lyman-α emission, discovered during a… CONTINUE READING
