Yun says that the LMT, which is operated jointly by UMass Amherst and INAOE, is uniquely suited for detecting a faint, broad line like this observational result and is designed specifically for this type of experiment. "Understanding how frequently the central supermassive black hole disrupts its host galaxy through a yet unknown energetic feedback process is one of the most important unanswered questions in the study of galaxy evolution today, and the LMT with its full 50-meter surface that was just completed, should yield more insights in the coming observing seasons," he says

Anna Lia Longinotti of the INAOE, who led the research, says "The novelty of this result is that we are seeing feedback in a galaxy where this phenomenon is not expected. The other two galaxies where it was observed are more dust- and gas-rich, whereas this galaxy is a spiral type, therefore more similar to the Milky Way. This discovery opens the path to explore the possibility that active galactic nuclei (AGN) feedback can be produced also by less luminous objects with different characteristics."
