OTELO Survey: Optimal Emission-Line Flux Determination with OSIRIS/GTC

Scritto in Pubblicazioni

Emission-line galaxies are important targets for understanding the chemical evolution of galaxies in the universe. Deep, narrowband imaging surveys allow detection and study of the flux and the equivalent widths (EWs) of the emission line studied. The present work has been developed within the context of the OTELO project, an emission-line survey using the tunable filters (TF) of OSIRIS, the first-generation instrument on the Gran Telescopio Canarias (GTC) 10.4 m telescope located in La Palma, Spain, that will observe through selected atmospheric windows that are relatively free of...

The GTC/OSIRIS Data Reduction System

Scritto in Pubblicazioni

We present the online and the offline data reduction system for OSIRIS,
the optical multi-mode instrument for GranTeCan. The software is written
in Python and invokes PyRAF tasks which have been optimized for the
instrument. We review the characteristics of the instrument and of the
software. We will also present the improvements which are foreseen for
both the instrument and the software. The flexibility of the software
makes it easy to be adapted to other telescopes/instruments.

Early-type galaxies in the EGS (Fernandez Lorenzo+, 2011)

Scritto in Pubblicazioni

Physical parameters for 135 early-type galaxies in the Extended Groth
Strip (EGS). For each galaxy equatorial coordinates, total magnitudes in
B and g-bands, redshift, velocity dispersion, effective radius, surface
brightness, stellar mass, Sersic index, type (elliptical or lenticular)
and signal-to-noise of the spectrum are given.
