Bechtold, Jill AST 96-17060 Dr. Bechtold will continue several programs to study the nature of distant quasars and the intergalactic and interstellar gas which lies along the line-of-sight to them. Observations will be in multiple wavelengths, including optical, near-infrared, sub-millimeter, radio and X-ray. The continuum radiation provides clues to the physical conditions of the supermassive black hole and accretion disk. The emission lines provide further clues to the geometry and radiation field near the nucleus. By studying the quasars as a function of redshift, the evolution of the quasar population as a whole may be understood.

Bechtold，Jill AST 96-17060 Bechtold博士将继续几个项目，研究遥远的类星体的性质以及沿着它们的视线的星系间和星际气体。 观测将在多个波长，包括光学，近红外，亚毫米，无线电和X射线。 连续辐射为超大质量黑洞和吸积盘的物理条件提供了线索。 发射谱线为了解原子核附近的几何形状和辐射场提供了进一步的线索。 通过研究类星体作为红移的函数，可以理解类星体总体的演化。
