Abstract:
The goal of this paper is twofold. Firstly, we present F-VIPGI, a new
version of the VIMOS Interactive Pipeline and Graphical Interface
(VIPGI) adapted to handle FORS2 spectroscopic data taken with the
standard instrument configuration. Secondly, we investigate the
spectro-photometric properties of a sample of galaxies residing in
distant X-ray selected galaxy clusters, the optical spectra of which
were reduced with this new pipeline.
Description:
We provide a library of spectroscopic templates in the
near-ultraviolet and optical range representative of the galaxy
population residing in distant, X-ray selected, galaxy clusters. The
studied targets belong to the redshift range 0.65≤z≤1.25 and are
drawn from the XMM-Newton Distant Cluster Project (XDCP) sample.
We used a total of 186 cluster galaxies we grouped in five different
spectral classes: passive, post-starburst, quiescent star-forming,
dusty starburst and starburst. All spectra within each group were
co-added to generate the empirical template representative of the
given spectral class. All galaxies were observed with the VLT-FORS2
spectrograph with the grism 300I+11, which provides a resolution of
R=660 and a wavelength coverage of 6000-10500Å. The spectra have
been reduced with F-VIPGI, the new semi-automated pipeline for FORS2
spectroscopy presented in this paper.
