Abstract.
We present APPLES, the ACS Pure Parallel Ly\(\alpha\) Emission Survey for Cycle 11, which is aimed to collect the largest and most uniform sample of high redshift Ly\(\alpha\) emitters ever pursued with HST. By using the Wide Field Channel of the Advanced Camera for Survey (ACS), we estimate to find 10 to 20 high redshift Ly\(\alpha\) emitters per ACS pointing down to a flux limit of 2 x 10-17 ergs cm-2 s-1 in two orbits, for a final sample of about 1000 Ly\(\alpha\) emitters, which will provide: a) robust statistics on the population and evolution of Ly\(\alpha\) emitters at \(4 \le z \le 7\); b) a measurement of the reionization redshift; and c) spatial clustering information for Ly\(\alpha\) emitters as a function of redshift.
