Discovery of a z=7.452 high equivalent width Lyα emitter from the Hubble Space Telescope faint infrared grism survey

We present the results of an unbiased search for Ly{\alpha} emission from continuum-selected 6 4{\sigma}) emission lines using two different automated detection methods, free of any visual inspection biases. Applying these methods on photometrically-selected high-redshift candidates between 6 7 (140.3 +/- 19.0{\AA}).
