We present a spectroscopically confirmed Lyman alpha emitter(hereafter LAE) samples at z 4.5 in the Extended Chandra Deep Field South region. With this sample, we analyze the 1) Lyman-alpha Luminosity functions; 2) spatial clustering; and 3) Lyman-alpha Equivalent Width distributions for photometric LAE candidates and confirmed LAEs at redshift z 4.5. The Lyman-alpha luminosity function and spatial clustering for our z 4.5 sample is
consistent with others published in the literature during the redshift range of 3 < z < 6, while
the Lyman-alpha luminosity functions in our two separate narrowband filters show a 2 Sigma difference. The difference is comparable to differences among z=5.7 and z=6.5 LyA luminosity functions.
We also did a Monte Carlo simulation of the Lyman-alpha equivalent width distribution. We found that the Lyman-alpha EW is independent of the Lyman-alpha line luminosity, and its distribution shows an exponential form.We gratefully acknowledge support from NSF grant NSF-AST-0808165.
