Searching for the Supermassive Black Hole in NGC 1265 (3C 83.1B)

摘要

We present K-band adaptive-optics assisted spectroscopic observations of the central region of the archetype head-tail radio galaxy NGC 1265 (3C 83.1), with the aim of constraining the mass of the supermassive black hole (MBH). The near-infrared data taken with the Altair–NIRI system on the Gemini North have a spatial resolution of FWHM = 0."11 (39 pc, at the galaxy's distance of 73 Mpc).
