The OTELO survey is a very deep, blind exploration of a selected region of the Extended Groth Strip and is designed for finding emission-line sources (ELSs). The survey design, observations, data reduction, astrometry, and photometry, as well as the correlation with ancillary data used to obtain a final catalogue, including photo-z estimates and a preliminary selection of ELS, were described in a previous contribution. Here, we aim to determine the main properties and luminosity function (LF) of the [O III] ELS sample of OTELO as a scientific demonstration of its capabilities, advantages, and complementarity with respect to other surveys. The selection and analysis procedures of ELS candidates obtained using tunable filter (TF) pseudo-spectra are described. We performed simulations in the parameter space of the survey to obtain emission-line detection probabilities. Relevant characteristics of [O III] emitters and the LF([O III]), including the main selection biases and uncertainties, are presented. A total of 184 sources were confirmed as [O III] emitters at a mean redshift z=0.83. The minimum detectable line flux and equivalent width (EW) in this ELS sample are $sim$5 $times$ 10$^{-19}$ erg s$^{-1}$ cm$^{2}$ and $sim$6 AA, respectively. We are able to constrain the faint-end slope ($alpha = -1.03pm0.08$) of the observed LF([O III]) at z=0.83. This LF reaches values that are approximately ten times lower than those from other surveys. The vast majority (84%) of the morphologically classified [O III] ELSs are disc-like sources, and 87% of this sample is comprised of galaxies with stellar masses of M$_star$ $<$ 10$^{10}$ M$_{odot}$.
We take advantage of the capabilities of the OTELO survey to select and study the AGN population in the field. We performed an analysis of the properties of these objects, including their demography, morphology, and IR luminosity. Focusing on the pop
We take advantage of the capability of the OTELO survey to obtain the H$alpha$ luminosity function (LF) at ${rm z}sim0.40$. Because of the deepest coverage of OTELO, we are able to determine the faint end of the LF, and thus better constrain the star
We present a result of a blind search for [CII] 158 $mu$m emitters at $zsim 4.5$ using ALMA Cycle~0 archival data. We collected extra-galactic data covering at 330-360 GHz (band~7) from 8 Cycle~0 projects from which initial results have been already
A study of [S III]$lambdalambda9096,9532$ emitters at $z$ = 1.34 and 1.23 is presented using our deep narrow-band $H_2S1$ (centered at 2.13 $mu$m) imaging survey of the Extended Chandra Deep Field South (ECDFS). We combine our data with multi-wavelen
We present new estimates of the luminosity function (LF) and star formation rate density (SFRD) for an H$alpha$ selected sample at $zsim0.62$ from the Deep And Wide Narrow-band (DAWN) survey. Our results are based on a new H$alpha$ sample in the exte
