Abstract:
We present the HI eXtreme (HIX) galaxy survey targeting some of the
most HI rich galaxies in the Southern hemisphere. The 13 HIX galaxies
have been selected to host the most massive HI discs at a given
stellar luminosity. We compare these galaxies to a control sample of
average galaxies detected in the HI Parkes All Sky Survey (HIPASS).
As the control sample is matched in stellar luminosity, we find that
the stellar properties of HIX galaxies are similar to the control
sample. Furthermore, the specific star formation rate and optical
morphology do not differ between HIX and control galaxies. We find,
however, the HIX galaxies to be less efficient in forming stars. For
the most HI massive galaxy in our sample (ESO075-G006,
logMHI[M☉]=(10.8±0.1)), the kinematic properties are the
reason for inefficient star formation and HI excess. Examining the
Australian Telescope Compact Array (ATCA) HI imaging and Wide Field
Spectrograph (WiFeS) optical spectra of ESO075-G006 reveals an
undisturbed galaxy without evidence for recent major, violent
accretion events. A tilted ring fitted to the HI disc together with
the gas-phase oxygen abundance distribution supports the scenario that
gas has been constantly accreted on to ESO075-G006 but the high
specific angular momentum makes ESO075-G006 very inefficient in
forming stars. Thus, a massive HI disc has been built up.
