Five cosmological simulations predict that the faint ultraviolet excess seen by the Condor telescope at z≈2.5 is Lyman-alpha light from the cosmic web, with measurable detection thresholds for wide-field surveys.

abstract
The Keck Wide-Field Imager (KWFI) is a proposed 1-degree diameter field of view UV-sensitive optical camera for Keck prime focus. KWFI will be the most powerful optical wide-field camera in the world and the only such 8m-class camera sensitive down to ~3000 A for the foreseeable future. Twenty science cases are described for KWFI compiled largely during 2019-2021, preceded by a brief discussion of the instrument, components, and capabilities for context.

The cosmic web's Lyman-$\alpha$ glow at $z \approx 2.5$; hydrodynamic models, dust, and wide-field, narrow-band detection
Five cosmological simulations predict that the faint ultraviolet excess seen by the Condor telescope at z≈2.5 is Lyman-alpha light from the cosmic web, with measurable detection thresholds for wide-field surveys.
