英文摘要
We have used the Subaru Telescope to take infrared spectra of a very distant, unusually bright, and massive elliptical galaxy. In contrast with previous studies, this galaxy appears to be similar to its cousins in the local Universe. Its size appears to be normal for its mass, and its velocity dispersion is consistent with its large size. This research deepens the puzzle as to how and why some elliptical galaxies seem to reach their full size very early in the evolution of the Universe while other, very compact ones increase in volume a hundredfold over time.
