He II Emission in Lyα Nebulae: Active Galactic Nucleus or Cooling Radiation?
We present a study of an extended Lyα nebula located in a known overdensity at z ∼ 2.38. The data include multiwavelength photometry covering the rest-frame spectral range from 0.1 to 250μm, and deep optical spectra of the sources associated with the
