Abstract:
In this paper, we present data from the Blind Ultra-Deep HI
Environmental Survey (BUDHIES), which is a blind 21-cm HI spectral
line imaging survey undertaken with the Westerbork Synthesis Radio
Telescope. Two volumes were surveyed, each with a single pointing and
covering a redshift range of 0.164<z<0.224. Within these two
volumes, this survey targeted the clusters Abell 963 and Abell 2192,
which are dynamically different and offer unique environments to study
the process of galaxy evolution within clusters. With an integration
time of 117x12h on Abell 963 and 72x12h on Abell 2192, a total
of 166 galaxies were detected and imaged in HI. While the clusters
themselves occupy only 4 per cent of the 73400Mpc3 surveyed by
BUDHIES, most of the volume consists of large-scale structures in
which the clusters are embedded, including foreground and background
overdensities and voids. We present the data processing and source
detection techniques and counterpart identification based on a
wide-field optical imaging survey using the Isaac Newton Telescope and
deep ultraviolet (UV) Galaxy Evolution Explorer (GALEX) imaging.
Finally, we present HI and optical catalogues of the detected sources
as well as atlases of their global HI properties, which include
integrated column density maps, position-velocity diagrams, global HI
profiles, and optical and UV images of the HI sources.
Description:
In this paper, we have presented the results of a blind, 21-cm HI
imaging survey with the WSRT, covering a redshift range of
0.164<z<0.224 in each of two pointings, thereby surveying a total
volume of 73-400Mpc3 within the FWQM of the primary beam with a
velocity resolution of 19km/s and an average angular resolution
of 23x38arcsec2.
A total of 166 galaxies are detected within the total survey volume,
none of which have been previously detected in HI. We have also
presented ancillary optical imaging data of the two fields in the
Harris B and R bands, obtained with the Wide-Field Camera on the INT
on La Palma.
In addition, we have obtained deep, near- and far-UV ancillary imaging
data of the two fields with the GALEX satellite.
