| Title: | MOS observations of z>4 galaxy candidates in the field of PMN2314+0201 | |||
| Modes: | MOS | |||
| Additional instrument verification: | Data reduction pipeline for MOS data; mask preparation software. | |||
| Telescope verification: | Acquisition and guiding with GMOS for tested mode. Stability of guiding over long periods of time and large hour angles. | |||
| Proposed observing sequence: | MOS: Multiple 30 min exposures | |||
| OT program file: | Not yet available | |||
| Science background: |
The aim is to obtain spectra of the z~4 galaxy candidates in the field of PMN2314+0201. The program is the start of the spectroscopic follow up for GMOS SV program 67. At first only a moderate exposure time would be necessary, to determine whether Ly-alpha emission is present in any of the candidate high-z objects. Deeper MOS observations would be necessary in the future (not necessarily as part of SV) in order to obtain redshifts for the galaxies which do not show Ly-alpha emission. |
