Abstract:
The GALEX Ultraviolet Virgo Cluster Survey (GUViCS) is a complete
blind survey of the Virgo cluster covering ∼40 sq. deg in the far UV
(FUV, λeff=1539Å, Δλ=442Å) and ∼120 sq.
deg in the near UV (NUV, λeff=2316Å,
Δλ=1060Å). The goal of the survey is to study the
ultraviolet (UV) properties of galaxies in a rich cluster environment,
spanning a wide luminosity range from giants to dwarfs, and regardless
of prior knowledge of their star formation activity. The UV data will
be combined with those in other bands (optical: NGVS; far-infrared -
submm: HeViCS; HI: ALFALFA) and with our multizone
chemo-spectrophotometric models of galaxy evolution to make a complete
and exhaustive study of the effects of the environment on the
evolution of galaxies in high density regions. We present here the
scientific objectives of the survey, describing the observing strategy
and briefly discussing different data reduction techniques. Using UV
data already in-hand for the central 12 sq. deg we determine the FUV
and NUV luminosity functions of the Virgo cluster core for all cluster
members and separately for early- and late-type galaxies and compare
it to the one obtained in the field and other nearby clusters (Coma,
A1367). This analysis shows that the FUV and NUV luminosity functions
of the core of the Virgo clusters are flatter (alpha~-1.1) than those
determined in Coma and A1367. We discuss the possible origin of this
difference.
