论文摘要
我们基于近红外CEPHEID周期时期关系和新的Hubble Space Multiband Imaging Imaging，我们将$ 15.8 \ pm0.4 $ mpc的距离到原型Seyfert 1 Galaxy NGC 4151。这种距离确定基于35个长期（$ p> 25 $ d）的测量结果，将支持该系统中超质量黑洞质量的绝对校准，以及对其活性银河系核的反馈或进食动力学的研究。
We derive a distance of $15.8\pm0.4$ Mpc to the archetypical Seyfert 1 galaxy NGC 4151 based on the near-infrared Cepheid Period-Luminosity relation and new Hubble Space Telescope multiband imaging. This distance determination, based on measurements of 35 long-period ($P > 25$d) Cepheids, will support the absolute calibration of the supermassive black hole mass in this system, as well as studies of the dynamics of the feedback or feeding of its active galactic nucleus.
