  摘要：

  我们展示了七个射电强类星体（具有2.1的中值红移）的近红外光谱，其中五个已知具有Lyα星云。六个天体周围显示出延展的[O iii] λ5007和Hα发射，位于核区≃2角秒（采用的宇宙学中的16千秒差距）内，亮度水平为每平方角秒每秒几乘以10^-16 尔格/平方厘米。在研究的五个类星体中，有三个在其波长上探测到了核区的[O ii] λ3727，其中一个明显延展。延展的[O iii]在具有较强类喷流射电发射的核区一侧更亮，表明至少非核区气体呈各向异性分布。它通常相对于核区[O iii]有数百公里每秒的红移，可能是由于后者相对于宿主星系的系统速度发生蓝移。或者，速度偏移可能是由于合并（由线宽≈1000公里每秒 FWHM 提示）结合适当的尘埃几何结构所致。远低于B值情况的Lyα/Hα比率表明存在一些尘埃。对延展气体中[O iii]/[O ii]比率的 photoionization 建模表明其压力约为或小于几乘以10^7 厘米^-3 K；因此，任何限制的星系团介质都可能伴随强烈的冷却流。与低红移工作的比较表明，在红移1到2之间，射电强类星体的核区发射线特性几乎没有演化。

  A photoactive compound is used in combination with a photosensitizer, represented by the following formula (1): A −[( J ) m −( X-Pro )] n (1) wherein A represents a hydrophobic unit comprising at least one kind of hydrophobic groups selected from a hydrocarbon group and a heterocyclic group, J represents a connecting group, X-Pro represents a hydrophilic group protected by a protective group Pro which is removable by light exposure, m represents 0 or 1, and n represents an integer of not less than 1. The protective group Pro may be removable by light exposure in association with the photosensitizer (especially, a photo acid generator), or may be a hydrophobic protective group. The hydrophilic group may be a hydroxyl group or a carboxyl group. The photoactive compound has high sensitivity to a light source of short wavelength beams, for resist application, therefore, the photoactive compound is advantageously used for forming a pattern with high resolution.
