AST-0071114SalzerThe goals of this project are to identify and analyze a volume limited sample of emission-line galaxies using the KPNO 0.6m Schmidt with an objective prism and a large-format CCD to find and measure the H-alpha emission from these objects. The stated objective is to locate ~5000 emission-line galaxies in 300 sq.deg. with B20-21. The survey is on-going; the analysis software has been developed and tested, and over 127 square deg. have already been analyzed. Once complete, the KISS sample of galaxies will have numerous additional applications which cut across many areas of research in astronomy, including chemical evolution in galaxies, the large-scale distribution of galaxies, and the determination of the abundance of helium produced in the Big Bang.Galaxies with active nuclei or intense starbursts represent the most energetic phenomena known in the universe. Galaxian activity is very common and occurs on all scales, from the super-luminous quasars down to extremely active star formation in dwarf galaxies. Much of our knowledge of active galaxies and starbursts has come about by studying galaxies cataloged in objective-prism surveys that used Schmidt telescopes and photographic plates. The recent opportunity to use more sensitive digital detectors has prompted the present program to discover much fainter active galaxies than were previously accessible. The KISS project (KPNO International Spectroscopic Survey), is designed to discover faint, distant galaxies which possess strong emission lines, a clear signature of galaxian activity. The survey technique used is extremely successful, discovering new active galaxies at a rate 180 times higher than the most well known previous survey of this type (the Markarian survey). To date a few thousand active and starbursting galaxies have been cataloged. The project will be continued by extending the observations to new areas of the sky. In addition, the large, deep samples will be usedto study galaxian activity of all types, in order to better understand this activity in the context of galaxy formation and evolution. Once the survey observations are complete, the KISS sample of galaxies will have numerous additional applications which cut across many areas of research in astronomy, including chemical evolution in galaxies, the large-scale distribution of galaxies, and the determination of the abundance of helium produced in the Big Bang. Funding for this project was provided by the NSF program for Extragalactic Astronomy & Cosmology (AST/EXC).***

AST-0071114 Salzer该项目的目标是使用带有物镜棱镜和大幅面CCD的KPNO 0. 6 m施密特来识别和分析发射线星系的体积有限样本，以发现和测量来自这些物体的H-α发射。规定的目标是在300 sq.deg.内定位~5000个发射线星系。B20-21调查正在进行中;分析软件已经开发和测试，超过127平方度。已经被分析过了。一旦完成，KISS星系样本将有许多额外的应用，这些应用涉及天文学的许多研究领域，包括星系的化学演化，星系的大规模分布，以及确定大爆炸中产生的氦的丰度。具有活跃核或强烈星暴的星系团是宇宙中已知的最具活力的现象。 银河系的活动是非常普遍的，发生在所有的尺度上，从超亮的类星体到矮星系中极其活跃的星星形成。 我们对活动星系和星暴的认识，大部分来自于对用施密特望远镜和照相底片进行的物棱镜巡天中所记录的星系的研究。 最近有机会使用更灵敏的数字探测器，促使目前的计划发现比以前更暗的活动星系。KISS项目（KPNO国际光谱巡天）旨在发现微弱的遥远星系，这些星系具有强烈的发射线，这是银河系活动的明显标志。所使用的调查技术是非常成功的，发现新的活动星系的速度比最著名的以前的调查（马卡良调查）高180倍。 到目前为止，已经有几千个活跃的星系和星爆星系被编目。该项目将通过将观测扩展到天空的新区域来继续进行。 此外，这些大而深的样本将用于研究所有类型的银河系活动，以便更好地了解星系形成和演化背景下的这种活动。一旦巡天观测完成，KISS星系样本将有许多额外的应用，这些应用跨越了天文学研究的许多领域，包括星系的化学演化，星系的大规模分布以及确定大爆炸中产生的氦的丰度。该项目的资金由美国国家科学基金会的河外天文宇宙学计划（AST/EXC）提供。
