H{beta} and Ly{alpha} emitting galaxies at z~2

DOI

We compare the H{beta} line strengths of 1.90<z<2.35 star-forming galaxies observed with the near-IR grism of the Hubble Space Telescope with ground-based measurements of Ly{alpha} from the HETDEX Pilot Survey and narrow-band imaging. By examining the line ratios of 73 galaxies, we show that most star-forming systems at this epoch have a Ly{alpha} escape fraction below ~6%.
