[62.02] Morphology and Spitzer Properties of Lyman Alpha Emitters at z=5.7

We present a study of Lyman Alpha Emitters (LAEs) from our narrow-band(NB816) survey of the GOODS-S field. This selects emission line galaxies at z=5.7. Using the GOODS-ACS images, we measure the Sersic parameters and Bulge/Disk ratios for the LAE sample. The distribution of the Sersic N values and B/D ratios indicates the LAEs are disk dominated systems. Properties of the LAE sample (i.e. rest-frame colors and magnitudes) of different morphological types are studied.

A total of 65 observations of CDF-S in all the four bands. Using IRAC luminosities of these sources, we study rest-frame properties of galaxies at z=5.7. The 8 micron wavelength samples the rest-frame near-IR J-band light. This is then used to constrain the integrated mass of these systems at z=5.7.
