The luminosity function of the Hβ emitters at z∼0.87 from the OTELO survey
Abstract
A sample of Hβ emission line sources (ELS) at z∼0.87 is studied in order to obtain an estimation of the luminosity function (LF) of star forming galaxies at this redshift. We draw our sample from the OSIRIS Tunable Emission Line Object (OTELO) survey. This survey uses the tunable filter of OSIRIS at the Gran Telescopio Canarias to perform a blind narrow-band observation of a selected field in the Extended Groth Strip. Its spectral resolution allows us to discriminate Hβ from [OIII], making it possible to measure emission-line fluxes at a limiting luminosity of log(LHβ)=39.07 erg s-1). This is the first time that the faint end of the Hβ luminosity function at z∼0.8 is obtained. We extend our results to the bright end by using previously published data.
