Descripción
We present the first results of a program aimed to study the stellar
populations of moderate luminosity X-ray selected Active Galactic Nuclei
(AGN) at intermediate redshifts. We use observations taken as part of
the Survey for High-z Absorption Red and Dead Sources (SHARDS) with the
optical instrument OSIRIS on the 10.4m Gran Telescopio Canarias (GTC).
SHARDS is an on-going ESO/GTC Large Programme that is observing the
GOODS-North cosmological field with 24 medium-band filters (22 of 17nm
and 3 of 25nm) in the spectral range 500-950nm. Although SHARDS was
originally designed to select and study the properties of high-z massive
and passively evolving galaxies, it can also provide very valuable
information about AGN at intermediate redshifts. We show that the SHARDS
observations provide sufficiently high spectral resolution (R˜50)
to detect broad absorption stellar features (e.g., the 4000Å{}
break) as well as emission lines and to estimate accurate photometric
redshifts. Together with the SHARDS observations we use the wealth of
multi-wavelength data from the UV to radio available for this
cosmological field to study the stellar populations and star formation
histories of AGN at z˜0.5-1.2.
