Abstract

We present the CIDA-UCM-Yale (Centro de Investigaciones de Astronomia, Universidad Complutense de Madrid, and Yale University) Survey (CUYS) for Hα + [N II] 6549, 6584 &ANGS; emission-line galaxies (ELGs) using objective-prism spectra. The most important properties of a catalogue with 427 entries and significant subsets are analysed. The complete sample contains 183 statistically confirmed ELGs in a sky area of 151 deg^2 and redshift up to 0.14. We determine the parameters of the Ha luminosity function using the Hα + [N II] flux directly measured on the ELG spectra in this sample, and the star formation rate density derived is in agreement with values reported in the literature. Finally, we study the clustering properties of local star-forming galaxies relative to quiescent ones from different perspectives. We find that ELGs avoid dense regions of quiescent galaxies and we propose a power-law expression to parametrize the relation between star formation rate density and environment volume density of ELGs.

We are especially grateful to CIDA colleagues who have participated in different discussions about topics directly involved in this paper. Special thanks to the night assistants O. Contreras, F. Moreno, R. Rojas and U. Sánchez and the professional observers L. Romero and D. Herrera of the Venezuelan National Astronomical Observatory for their constant effort. We also acknowledge the useful suggestions from an anonymous referee. The alternative calculation of the LF(Hα) using an extintion correction estimated from a correlation between MB and E(B − V ) is included in the referee’s recommendations. The observations reported in this paper were done under the Scientific and Academic Collaboration Agreement signed between the Universidad Complutense de Madrid (UCM), España, and the Centro de Investigaciones de Astronomía “Francisco J. Duarte” (CIDA), Venezuela, in force since 1996 until end of 1999. Funding for the Sloan Digital Sky Survey (SDSS) has been provided by the Alfred P.
