NIBLES:对局部SDSS星系的HI普查

NIBLES: an HI census of local SDSS galaxies

W. van Driel, S. Schneider, M. Lehnert, the NIBLES Consortium

摘要:

NIBLES是法国100米级Nancay射电望远镜(NRT)的重点项目。其目的是对本地体积(900<cz<12,000 km/s)中4,000个斯隆数字巡天星系的HI气体含量和动力学进行普查。这些星系是根据它们的总恒星质量(绝对z波段星等Mz)选择的,并且均匀分布在本地SDSS星系所覆盖的整个Mz范围内(-10至-24等,H 0 =70 km/s/Mpc)。正在对600多个星系进行试点调查。NIBLES将补充ALUNAFA和EBHIS盲HI调查,这将探测到不同的本地星系系综,我们的试点调查结果表明,将探测到大约40-45%的NIBLES样本。NIBLES是一个开放的合作,任何对科学感兴趣并愿意为该项目做出贡献的人都欢迎加入NIBLErS。

英文摘要:

NIBLES is a Key Project proposed for the 100m-class Nancay Radio Telescope (NRT) in France. Its aim is a census of the HI gas content and dynamics of 4,000 Sloan Digital Sky Survey galaxies in the Local Volume (900<cz<12,000 km/s). The galaxies were selected based on their total stellar mass (absolute z-band magnitude Mz), and are distributed evenly over the entire range of Mz covered by local SDSS galaxies (-10 to -24 mag, for H0=70 km/s/Mpc). A pilot survey is being made of over 600 galaxies. NIBLES will be complementary to the ALFALFA and EBHIS blind HI surveys, which will detect a different ensemble of local galaxies, and which our pilot survey results indicate will detect about 40-45% of the NIBLES sample. NIBLES is an open collaboration and anyone interested in the science and willing to contribute to the project is welcome to join the score of NIBLErS.
