Since then, The NASA/IPAC Extragalactic Database (NED) gives 123 citations for H11.[2] The first study showing the possible escape of Lyman continuum photons was published in 2006, using data from the Far Ultraviolet Spectroscopic Explorer (FUSE).[3] The study's aim was to select "an extreme starburst dwarf, the Blue Compact Galaxy Haro 11, with the aim of determining the Lyman continuum escape fraction from UV spectroscopy."[5]
