Low surface brightness galaxies (LSBGs) are defined as galaxies that are fainter than dark night sky and are important for studying our universe. Particularly, edge-on galaxies are useful for the study of rotational velocity and dynamical properties of galaxies. Hence here we focus on searching for edge-on LSBGs. In order to find these edge-on dim galaxies, a series of effects caused by inclination, including the surface brightness profile, internal extinction, and scale length, have been corrected. In this work, we present a catalog of 281 edge-on LSBG candidates, which are selected from the crossmatch between Sloan Digital Sky Survey Data Release 7 and the 40% ALFALFA catalog. We also present the properties of these edge-on LSBG candidates including the absolute magnitude, central surface brightness, B − V color, scale length, and relative thickness. Our result suggests that the correction of inclination effects is very important for obtaining a complete sample o...

40%ALFALFA目录中富含边缘高H i低表面亮度银河候选物的样品

低表面亮度星系(LSBG)被定义为比漆黑的夜空微弱的星系,对研究我们的宇宙很重要。特别地,边缘星系可用于研究星系的旋转速度和动力学特性。因此,在这里我们专注于搜索边缘LSBG。为了找到这些边缘暗星系,已校正了由倾斜引起的一系列影响,包括表面亮度分布,内部消光和标尺长度。在这项工作中,我们提供了281种边缘LSBG候选者的目录,这些候选项是从Sloan Digital Sky Survey Data Release 7和40%ALFALFA目录之间的交叉匹配中选择的。我们还介绍了这些边缘LSBG候选对象的属性,包括绝对大小,中心表面亮度,B-V颜色,标度长度,和相对厚度。我们的结果表明,倾斜效果的校正对于获得完整的样品样品非常重要。
