Abstract:
This is the second u-band extension of the WIde-field Nearby
Galaxy-cluster Survey (WINGS), obtained by imaging 39 clusters with
the ESO-VLT survey telescope. It follows the first one, realized with
several telescopes of the northern hemisphere in the U Cousin-Bessel
filter band (Omizzolo et al., 2014A&A...561A.111O 2014A&A...561A.111O, Cat.
J/A+A/561/A111), that covered 17 clusters.
The u-band data, in combination with those already achieved by the
WINGS survey, will permit a detailed multi-wavelength investigation of
the properties of the member galaxies from the cluster center out to
the periphery.
We have derived with SEXT the main properties of the galaxies in the
observed fields and measured the u-V colors on circular apertures of
increasing radius. The photometric accuracy of the magnitudes has been
calibrated with the standard stars and tested by means of comparisons
with the u-band data of the Sloan Digital Sky Survey (SDSS).
We present the catalogs of the photometric analysis performed by SEXT.
Then we provide a brief analysis of the u-V vs V color-magnitude
diagram of our clusters, the plots of the color as a function of the
cluster-centric distance (for cluster members only) and the
correlation of the current star formation rate (SFR) vs the absolute V
and u magnitudes for the galaxies in the observed fields.
Description:
u-band photometric parameters for thousand of galaxies in the regions
of 39 clusters of the WINGS survey.
