The process that was called nuclear feeding of the galaxy NGC 1566's supermassive black hole

An article published in the journal “Monthly Notices of the Royal Astronomical Society” reports a study on the feeding process of the supermassive black hole at the center of the galaxy NGC 1566. A team of researchers led by Almudena Prieto of the Instituto de Astrofísica de Canarias (IAC) used observations conducted with the Hubble Space Telescope, the VLT, and the ALMA radio telescope in Chile to be able to visualize filaments of interstellar dust that separate and subsequently head towards the supermassive black hole, approaching it in a spiral trajectory that eventually leads them to be swallowed. Those filaments could obscure the center of many galaxies with active galactic nuclei.
