Searching for Accreting Black Holes in Lyman Continuum Emitters

The early universe was reionized, likely by UV light from massive stars. The two galaxies from which Lyman continuum radiation has been directly observed are both very luminous X-ray sources and the emission from one, Haro 11, is dominated by a hard-spectrum point-like source that is likely one or more accreting compact objects. Such objects can produce powerful outflows, rivaling the strength of stellar winds and supernovae, that prevent scattering and allow the Lyman emission to escape. We propose to observe with Chandra for the first time the other confirmed Lyman emitter and also to observe several recently identified Lyman emitter candidates. We will determine if there is a correlation between strong X-ray emission and Lyman continuum emission.
