论文摘要
在本文中，我们使用宽银河动物园公民科学项目的数据版本1介绍了五个以前未知的巨型宽道星系（GRG），以及一种适合于培训和验证新无线电调查的深度学习算法的选择方法。我们将这些新GRG之一与星系集群GMBCG J251.67741+36.45295相关联，将这些新的GRG与最亮的集群星系（BCG）相关联，并使用文献数据将先前已知的GRG识别为BCG候选者，从而增加了已知的BCG GRG的数量，增加了BCG GRG的数量。通过检查所有已知的BCG GRG数量的本地星系数密度，我们建议这种越来越多的数量的存在意味着GRG可以驻留在富人的中心（$ \ sim 10^{14} $ m $ _ {\ odot} $）星系群，并挑战了该假设，使得grgs supply supply did supply suppers supply supply suppers sivess sivess s s s s s s s s s s s s s s s s s s s s s s s s s s s s s s s s s s s s s s s s s s s s s s sy-Sivess siles中所构成。
In this paper, we present the identification of five previously unknown giant radio galaxies (GRGs) using Data Release 1 of the Radio Galaxy Zoo citizen science project and a selection method appropriate to the training and validation of deep learning algorithms for new radio surveys. We associate one of these new GRGs with the brightest cluster galaxy (BCG) in the galaxy cluster GMBCG J251.67741+36.45295 and use literature data to identify a further 13 previously known GRGs as BCG candidates, increasing the number of known BCG GRGs by >60%. By examining local galaxy number densities for the number of all known BCG GRGs, we suggest that the existence of this growing number implies that GRGs are able to reside in the centers of rich ($\sim 10^{14}$ M$_{\odot}$) galaxy clusters and challenges the hypothesis that GRGs grow to such sizes only in locally under-dense environments.
