The Deimos Spectrograph and a Planned DEEP Redshift Survey | | Marc Davis

30 Oct 1998 | | Subject: | astro-ph | | Affiliation: | Berkeley) and Sandra M. Faber (UCSC | | Abstract: | A second generation spectrograph for the Keck telescope is under construction at the Lick Observatory shops and will be delivered to Hawaii in 1999. Starting in the Fall of 1999, we shall begin the second phase of the DEEP project: a dense redshift survey of galaxies at Z=1. With each pointing of DEIMOS we shall obtain simultaneous short slit spectra of 70-100 galaxies with $m_I(AB) < 23.0$ in a field of 15’ by 2’. Four regions of the sky will be studied in detail, with dense sampling in a region of 120’x15’ in each region, plus outrigger fields. The galaxies for spectroscopic analysis will be selected by flux limit and by photometric redshift estimate $Z_{photo}>0.7$. The goal is to obtain high quality spectra of perhaps 30,000 galaxies over the course of 2-3 years. We here review the status of DEIMOS and the science objectives of the survey. | | Source: | arXiv, astro-ph/9810489 | | Services: | Forum | Review | PDF | Favorites | |
