Unveiling the Enigmatic Expansions of Black Holes: VERA Telescope Network Sheds Light

Using the VERA network of radio telescopes, astronomers have discovered significant Faraday rotation in polarized radio waves from Narrow-line Seyfert 1 galaxies, indicating the presence of abundant gas and facilitating the rapid growth of young supermassive black holes. This research provides new insights into the formation and evolution of these celestial entities.
