Abstract:
The evolution of galaxies through cosmic time is studied
observationally by means of extragalactic surveys. The usefulness of
these surveys is greatly improved by increasing the cosmological
volume, in either depth or area, and by observing the same targets in
different wavelength ranges. A multi-wavelength approach using
different observational techniques can compensate for observational
biases.
The OTELO survey aims to provide the deepest narrow-band survey to
date in terms of minimum detectable flux and emission line equivalent
width in order to detect the faintest extragalactic emission line
systems. In this way, OTELO data will complements other broad-band,
narrow-band, and spectroscopic surveys.
The red tunable filter of the OSIRIS instrument on the 10.4m Gran
Telescopio Canarias (GTC) is used to scan a spectral window centred at
9175Å, which is free from strong sky emission lines, with a
sampling interval of 6Å and a bandwidth of 12Å in the most
deeply explored EGS region. Careful data reduction using improved
techniques for sky ring subtraction, accurate astrometry, photometric
calibration, and source extraction enables us to compile the OTELO
catalogue. This catalogue is complemented with ancillary data ranging
from deep X-ray to far-infrared, including high resolution HST images,
which allow us to segregate the different types of targets, derive
precise photometric redshifts, and obtain the morphological
classification of the extragalactic objects detected.
The OTELO multi-wavelength catalogue contains 11 237 entries and is
50% complete at AB magnitude 26.38. Of these sources, 6600 have
photometric redshifts with an uncertainty δ zphot better than
0.2 (1+zphot). A of 4336 of these sources correspond to
preliminary emission line candidates, which are complemented by 81
candidate stars and 483 sources that qualify as absorption line
systems. The OTELO survey results will be released to the public on
the second half of 2019.
Description:
OTELO is a very deep, 2D spectroscopic (resolution R∼700) blind
survey, defined on a window of 230Å, centred at 9175Å. The first
pointing of OTELO targets a region of the Extended Groth Field
embedded in Deep field 3 of the Canada-France-Hawaii Telescope Legacy
Survey (CFHTLS, http://www.cfht.hawaii.edu/Science/CFHTLS) and the
deepest pointing of GALEX in imaging and spectroscopy. OTELO obtains
pseudo-spectra of all emission line sources in the field, sampling
different cosmological volumes between z=0.4 and 6, thereby providing
valuable data for tackling a wide variety of science projects, which
include the evolution of star formation density up to redshift ∼1.5,
an approach to the demographics of low-luminosity emission-line
galaxies and detailed studies of emission-line ellipticals in the
field, high-z QSO, Lyman-alpha emitters, and Galactic emission stars
(Cepa et al. 2013, SPIE, 4841, 1739). Such pseudo-spectra were
obtained by means of the red tunable filter (RTF) of the OSIRIS
instrument at GTC. For further details of the OSIRIS instrument see
Cepa et al. (2003, SPIE, 4841, 1739).
