Turnshek, David AST 96-17151 Dr. Turnshek will study quasars in collaboration with astronomers in Moscow (Russia) and Tashkent (Uzbekistan) to monitor brightness variations in quiescent QSOs and to correlate the variations with other QSO properties. A sample of moderate redshift, i.e. z is in the range from 1.5 to 2.5, has some observations back to 1987, but entered a new phase with the recent loan of the University of Pittsburgh CCD camera to Maidanak Observatory in Uzbekistan.

Turnshk博士将与莫斯科(俄罗斯)和塔什干(乌兹别克斯坦)的天文学家合作研究类星体，以监测静止类星体的亮度变化，并将这种变化与其他类星体特性相关联。一个中等红移的样本，即z在1.5到2.5的范围内，早在1987年就有一些观测，但随着最近匹兹堡大学的CCD相机借给乌兹别克斯坦的Maidanak天文台，进入了一个新的阶段。
