An Atlas of Galaxies in the Near Infrared: A Study of Structure and Stellar Content

点击翻译按钮获取中文摘要

Multiwavelength surveys of galaxies are of great importance for investigations of structure and stellar content. The research to be carried out will be a new, extensive survey of spiral galaxies using wide-field infrared and optical imaging systems developed at The Ohio State University. Infrared observations are key to this survey because infrared light is a better tracer of the stellar mass distribution than optical light and the effects of internal absorption by dust are minimized. Photometry and infrared long-slit spectroscopy will be used to study the dependence of stellar content on position, including the identification of regions of active star formation. The effects of scattering and absorption by dust on the observed luminosity and color of a galaxy will be investigated.
