Galaxies in the field of RX J0054.0-2823

We present galactic spectroscopic data from a pencil beam of 10.75'x7.5' centered on the X-ray cluster RXJ0054.0-2823 at z=0.29. We study the spectral evolution of galaxies from...本文提供了以红移（redshift）z=0.29处的X射线星系团（X-ray cluster）RXJ0054.0-2823为中心、尺寸为10.75′×7.5′的笔形波束的星系光谱数据。我们将研究星系的光谱演化，从...
