Book excerpt: We present 36 spectroscopically confirmed Lyman-alpha emitting galaxies (LAEs) from follow-up observations with Keck/DEIMOS of high-redshift candidates behind 10 galaxy cluster lenses. High-redshift candidates were selected to be between 5 [less than or approximately equal to] z [less than or approximately equal to 7] from a variety of photometric data using HST and Spitzer imaging surveys including the Cluster Lensing And Supernova Survey with Hubble (CLASH), the Hubble Frontier Fields (HFF), and the Spitzer UltRa Faint SUrvey Program (SURFSUP). A subset of 27 of our targets were prioritized from the Grism Lens-Amplified Survey from Space (GLASS). After compiling a large sample of potential high-redshift candidates from our extensive spectroscopic program, we used photometric redshift information derived from accompanying photometric data to perform an integrated P(z) cut >1% between 5 z 7 in order to construct a sample of 198 high-redshift objects, 136 primary targets and 62 secondaries (serendipitous objects). Our high-redshift sample spans intrinsic UV luminosities from a few L* down to 0.001L* (where L* is the characteristic luminosity of galaxies in our redshift range). We identified 19 high-confidence detections of Ly[alpha] in our final sample and an additional 17 likely detections. Five of these detections have been previously reported spectroscopically. We divided our sample into a lower-redshift (z [approximately equal to] 5.5) and higher-redshift (z [approximately equal to] 6.5) sample and ran Monte Carlo trials, incorporating the strength of the Ly[alpha]emission, the photometric redshift of the non-detections, and different treatments of multiple images. Considering only objects where Ly[alpha]could be detected at EW(Ly[alpha])25Å at 3[sigma] at the fiducial depth of our survey, and considering only those galaxies with EW(Ly[alpha])25Å as true LAEs, and finally, considering only objects with m[subscript AB]
