BLAGNs and NLS1s characteristics.

investigated narrow-line Seyfert 1 galaxies (NLS1s) at optical, mid-infrared (MIR), and X-ray wavelengths, comparing them to the broad-line active galactic nuclei (BLAGNs). We...本研究针对光学、中红外（mid-infrared，MIR）及X射线波段的窄线赛弗特1星系（narrow-line Seyfert 1 galaxies，NLS1s）开展观测研究，并将其与宽线活动星系核（broad-line active galactic nuclei，BLAGNs）进行对照分析。我们……
