The Cepheid Distance to the Seyfert 1 Galaxy NGC 4151

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, wil...

Description
Summary: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.
