摘要

CHIME/FRB 项目最近发布了其首份快速射电暴(FRBs)目录,包含 492 个独特源。我们呈现 CHIME/FRB 源与星系目录的角互相关结果。我们发现 CHIME FRB 与红移范围 $0.3 \lesssim z \lesssim 0.5$ 内星系在三个测光星系巡天:WISE $\times$ SCOS、DESI-BGS 与 DESI-LRG 之间存在统计显著的( $p$ 值 $\sim 10^{-4}$ ,已考虑四处寻找因子)互相关。互相关的程度与在该红移范围内 CHIME FRB 中有序一比例与巡天星系处于相同暗物质晕中相一致。我们发现存在具有大宿主色散量( $\sim 400$ pc cm $^{-3}$ )的 FRB 族群的统计证据,并表明这可合理源于大晕( $M \sim 10^{14} M_\odot$ )中的气体,对于晕中心附近的 FRB( $r \lesssim 100$ kpc)。这些结果将在未来的 CHIME/FRB 目录中随更多 FRB 与更好角分辨率而得以改进。
