| 英文摘要 | Our work is based on the 'Bluedisk' project, a programme to map the neutral gas in a sample of 25 HI-rich spirals and a similar number of control galaxies with the Westerbork Synthesis Radio Telescope (WSRT). In this paper, we focus on the H I properties of the galaxies in the environment of our targeted galaxies. In total, we extract 65 galaxies from the WSRT cubes with stellar masses between 10(8) and 10(11) M-circle dot. Most of these galaxies are located on the same H I mass-size relation and 'H I-plane' as normal spiral galaxies. We find that companions around H I-rich galaxies tend to be H I-rich as well and to have larger R-90, (H I)/R-50,R- H (I). This suggests a scenario of 'H I conformity', similar to the colour conformity found by Weinmann et al.: galaxies tend to adopt the HI properties of their neighbours. We visually inspect the outliers from the H I mass-size relation and galaxies which are offset from the H I plane and find that they show morphological and kinematical signatures of recent interactions with their environment. We speculate that these outliers have been disturbed by tidal or ram-pressure stripping processes, or in a few cases, by accretion events. |
