我们提出了一种新的方法来寻找高红移星系,这是基于一个中间带dropout技术,而不是通常的宽带dropout之一。在这种方法中,我们使用一个中心波长大于7000 \AA的中带滤波器。这种新的方法使得区分非常晚型的恒星,如L和T矮星和尘埃星系在中等红移的真实的高z$莱曼破裂星系。其原因是,这样的闯入者并没有表现出强烈的中间带抑郁症,虽然他们有很红的宽带颜色,这是莱曼破裂星系的指示。应用我们的新方法与斯巴鲁望远镜上的Suprime-Cam获得的成像数据集,我们发现了一个新的样本莱曼打破星系在$z \simeq 5$。
We propose a new method to search for high-redshift galaxies that is based on an intermediate-band dropout technique rather than the usual broad-band dropout one. In this method, we use an intermediate-band filter whose central wavelength is longer than 7000 \AA. This new method makes it possible to distinguish both very late-type stars such as L and T dwarfs and dusty galaxies at intermediate redshift from real high-$z$ Lyman break galaxies. The reason for this is that such interlopers do not show strong intermediate-band depression although they have very red broad-band colors that are indicative of Lyman break galaxies. Applying our new method to imaging data sets obtained with the Suprime-Cam on the Subaru Telescope, we find a new sample of Lyman break galaxies at $z \simeq 5$.
