Dalcanton, JulianneUniversity of WashingtonAST-9900862Dr. Dalcanton will study the formation of spiral galaxies, through two distinct approaches. The first will concentrate on studying the formation and evolution of galaxy disks and the second the formation of galaxy bulges. The aim is to provide direct measurements of physical quantities which either control galaxy formation, such as mass or angular momentum, or describe galaxy evolution, such as timing and metallicity. A variety of observational data, including optical and near IR images, optical spectroscopy and HI maps, will be used to provide the basic data from which mass distributions, star formation histories and metallicities will be determined.

Dalcanton，julianneuniversity of Washingtonast-9900862dr。达尔坎顿将通过两种不同的方法研究螺旋星系的形成。 第一个将集中于研究星系盘的形成和演变，第二个是星系凸起的形成。 目的是提供直接测量物理量的测量，这些物理量控制星系形成，例如质量或角动量，或描述星系演化，例如时序和金属性。 各种观察数据，包括光学图像和近红外图像，光谱和HI地图，将用于提供基本数据，从中确定质量分布，恒星形成历史和金属率的基本数据。
