论文摘要
无线电狭窄的窄线Seyfert 1个星系（NLS1），尤其是极端无线电的星系，被广泛接受为NLS1的喷射版本。我们探索了NLS1的无线电大分，最近发布的Lots DR1的150 MHz。批次DR1的无线电检测率约为28 \％。无线电检测到的NLS1的红移低于未检测的NLS1。此外，批次检测到的NLS1的150 MHz无线电发光度大约比以前的样品弱两个数量级。通过以150 MHz无线电通量和SDSS \ TextIt {R}频段磁通量在150 MHz无线电磁通量之间定义无线电响度，无线电大声分数约为1 \％，与100相等的关键无线电响度相等。无线电响度没有显示中央黑洞质量的依赖，而无线电响度和磁盘的散发性和Disk LuminIssusity和disk LuminIssusive n和Eddington ruddington bation均未发现。
Radio-Loud narrow-line Seyfert 1 galaxies (NLS1s), especially the extremely radio-loud ones, are widely accepted as the jetted versions of NLS1s. We explore the radio-loud fraction for NLS1s with recently released LoTSS DR1 at 150 MHz. The radio detection rate is about 28\% for LoTSS DR1. The radio detected NLS1s have lower redshift than the non-detected ones. Moreover, the 150 MHz radio luminosity of NLS1s detected by LoTSS are about two orders of magnitude weaker than that of the previous samples. By defining the radio loudness with the ratio between 150 MHz radio flux and SDSS \textit{r} band flux, the radio-loud fraction is about 1\% with the critical radio loudness equalling to 100. Radio loudness shows no dependence on central black hole mass, while weak correlations are found between radio loudness and disk luminosity, as well as Eddington ratio.
