We have studied in detail the properties of local active star-forming galaxies from the UCM survey, and in particular their star-formation histories. We have quantified the relative importance of the current episode of star formation in comparison to the underlying older stellar populations. We have also determined the total stellar mass function

We present the results of a morphological analysis of a small subset of the SWIRE galaxy population. Our analysis is based on public ACS data taken inside the SWIRE N1 field. We distinguish two very general classes of galaxies, bulge- and disc-dominated galaxies, the first class being referred to with the general term 'spheroids' and the second

We present our first attempt to model a new metallicity indicator for old and intermediate aged stellar populations on the basis of the Mg[b] absorption index at λ ˜ 5175 Å. Model spectra of stellar populations are convolved with the responses of the Tunable Filters of OSIRIS-GTC to provide a photometric index matching the spectroscopic Mg[b]. The

The complete catalogue of Wolf-Rayet (W-R) stars was used to search for new IRAS structures, traced by HiRes maps. The dust temperature was computed in all the fields. Different morphologies and temperature gradients around the stars were noted. Although these results should be considered as preliminary, they illustrate the relationship between

In this paper we discuss the detection of Ly α galaxies at 4.6 ≳ z ≳ 6.6 within the OTELO survey. We estimate the expected number of objects that will be found in this survey.

We propose to use the OSIRIS tunable filters to perform for the first time a systematic study of the environment of Radio Loud and Radio Quiet quasars in windows around a large range of redshifts (z ~ 2 to 4). The aim of our study is (1) to search for the presence of forming clusters of galaxies around quasars, through Ly α emitters, which in turn
