论文摘要
在这里，我简要介绍了我们对基于“本地卷HI调查”（LVHIS，Koribalski等人2018）的附近矮星系中气体含量，运动学和星形形成的研究，该研究是与澳大利亚望远镜压实（ATCA）一起进行的。 LVHIS样品由近100个星系组成，包括新发现，涵盖了大小，形状，质量和特殊性程度的巨大多样性。分析了两个附近两个组中矮星系的氢特性，即雕塑家和Cena / M83，并与许多相当孤立的矮星系进行了比较。大约10％的LVHIS星系是过渡或混合型矮星系（DIRR/DSPH），探索了其形成。 - 我还提供了有关小袋鼠早期科学的简短更新，我们专注于研究星系的HI特性作为环境的函数。与澳大利亚的Ska Pathfinder（Askap）进行袋鼠（dec <+30 degr，z <0.26），这是一个直径为6公里的36 x 12 m菜肴，每盘均为6公里，每个菜肴都配备了广阔的场（30平方degr）Chequerboard型伪造阵列。
Here I briefly highlight our studies of the gas content, kinematics and star formation in nearby dwarf galaxies (D < 10 Mpc) based on the `Local Volume HI Survey' (LVHIS, Koribalski et al. 2018), which was conducted with the Australia Telescope Compact Array (ATCA). The LVHIS sample consists of nearly 100 galaxies, including new discoveries, spanning a large diversity in size, shape, mass and degree of peculiarity. The hydrogen properties of dwarf galaxies in two nearby groups, Sculptor and CenA / M83, are analysed and compared with many rather isolated dwarf galaxies. Around 10% of LVHIS galaxies are transitional or mixed-type dwarf galaxies (dIrr/dSph), the formation of which is explored. - I also provide a brief update on WALLABY Early Science, where we focus on studying the HI properties of galaxies as a function of environment. WALLABY (Dec < +30 degr, z < 0.26) is conducted with the Australian SKA Pathfinder (ASKAP), a 6-km diameter array of 36 x 12-m dishes, each equipped with wide-field (30 sq degr) Chequerboard Phased Array Feeds.
