Abstract

The mid/far infrared hosts a wealth of spectral information that allows direct determination of the physical state of matter in a large variety of astronomical objects, unhindered by foreground obscuration. Accessing this domain is essential for astronomers to much better grasp the fundamental physical processes underlying the evolution of many types of celestial objects, ranging from protoplanetary systems in our own milky way to 10-12 billion year old galaxies at the high noon of galaxy formation in our universe. The joint ESA/JAXA SPICA mission will give such access for the astronomical community at large, by providing an observatory with unprecedented mid- to far-infrared imaging, polarimetric and spectroscopic capabilities.

联合红外空间天文台SPICA:揭开被遮蔽的宇宙

中/远红外拥有丰富的光谱信息，可以直接确定各种天文物体中物质的物理状态，而不受前景遮挡的阻碍。进入这个领域对于天文学家更好地掌握多种天体演化的基本物理过程至关重要，从我们银河系中的原行星系统到我们宇宙中星系形成高峰期的100 - 120亿年前的星系。ESA/JAXA的SPICA联合任务将通过提供一个具有前所未有的中远红外成像、偏振和光谱能力的天文台，为广大天文学界提供这样的机会。
