We present the Texas Euclid Survey for Lyman-Alpha (TESLA), a spectroscopicsurvey in the 10 square degree of the Euclid North Ecliptic Pole (NEP) field.Using TESLA, we study how the physical properties of Lyman-alpha emitters(LAEs) correlate with Lyman-alpha emission to understand the escape of Lymanalpha from galaxies at redshifts 2 -- 3.5. We present an analysis of 43 LAEsperformed in the NEP field using early data from the TESLA survey. We useSubaru Hyper Suprime-Cam imaging in the grizy-bands, Spitzer/IRAC channels 1and 2 from the Hawaii 20 square degree (H20) survey and spectra acquired by theVisible Integral-Field Replicable Unit Spectrograph (VIRUS) on the Hobby-EberlyTelescope. We perform spectral energy distribution (SED) fitting to compute thegalaxy properties of 43 LAEs, and study correlations between stellar mass, starformation rate (SFR), and dust, to the Lyman-alpha rest-frame equivalent widths(EW). We uncover marginal (1 sigma significance) correlations between stellarmass and Lyman-alpha EW, and star formation rate (SFR) and Lyman-alpha EW, witha Spearman correlation coefficient of -0.$34_{-.14}^{+.17}$ and-0.$37_{-.14}^{+.16}$ respectively. We show that the Lyman-alpha distributionof the 43 LAEs is consistent with being drawn from an exponential distributionwith an e-folding scale of 150 Angstrom. Once complete the TESLA survey willenable the study of ~ thousands of LAEs to explore correlations between galaxyproperties and Lyman-alpha EW. The large sample size will allow theconstruction of a predictive model for the Lyman-alpha EW as a function ofSED-derived galaxy properties, which could be used to improve Lyman-alpha basedconstraints on reionization.
