OMEGA - OSIRIS Mapping of Emission-line Galaxies in A901/2 - II. Environmental influence on integrated star formation properties and AGN activity

Rodrıguez del Pino, Bruno; Aragon-Salamanca, A.; Chies-Santos, A. L.; Weinzirl, Tim; Bamford, Steven P.; Gray, M. E.; Bohm, A.; Wolf, Christian; Maltby, David T.


We present a study of the star formation and AGN activity for galaxies in CP 15051 the Abell 901/2 multicluster system at z ∼ 0.167 as part of the OSIRIS Mapping of Emission-line Galaxies in A901/2 (OMEGA) survey. Using Tuneable Filter data obtained with the OSIRIS instrument at the Gran Telescopio Canarias, we produce spectra covering the Hα and [N II] spectral lines for more than 400 galaxies. Using optical emission-line diagnostics, we identify a significant number of galaxies hosting AGN,...[Show more]
