Extreme line profile variations in the repeating changing-look active galactic nucleus IRAS 23226-3843

Aims. IRAS 23226-3843 has been identified as a highly variable Seyfert galaxy and even as a changing-look active galactic nucleus based on optical spectra. Here we present follow-up observations – taken over the past five years – for examining the ongoing photometric and spectral variations in this...
