给出了对 41 个射电星系样本的 HST I 波段成像的分析结果，其射电光度在红移 z ≃ 0.5 处跨越三个数量级。这些结果代表了协调计划的第一阶段，该计划旨在研究射电光度与宿主星系特性、黑洞质量和射电星系中的星团环境之间的联系，这些射电星系在红移的有限范围内跨越了广泛的射电光度范围。完整样本由四个完整的、低频选定的无线电样本（3CRR、6CE、7CRS 和新的 TexOx-1000 样本）中提取的对象组成，这些样本的通量密度限制逐渐变弱。 HST 成像数据的建模表明，主星系的表面亮度分布与
The results of analysis of HST I−band imaging of a sample of 41 radio galaxies spanning three orders of magnitude in radio luminosity at redshift z ≃ 0.5 are presented. These results represent the first stage in a coordinated programme to study the connection between radio luminosity and host-galaxy properties, black-hole masses and cluster environments in radio galaxies spanning a wide range in radio luminosity over a restricted range in redshift. The full sample is comprised of objects drawn from four complete, low-frequency selected radio samples with progressively fainter flux-density limits (3CRR, 6CE, 7CRS and the new TexOx-1000 sample). Modelling of the HST imaging data shows that the host galaxies have surface-brightness distributions con
