Radio transients are short-lived sources of radio radiation that can occur near supermassive black holes in galaxy centers under extreme physical conditions. The galaxy SDSS J110546.07+145202.4 is unique as it has been emitting strong radio light for several years, unlike most radio transients that typically last only days or weeks.

Short-lived sources of radio radiation in the sky, known as radio transients, can originate in the vicinity of supermassive black holes in the centers of galaxies. They are the result of processes that take place under extreme physical conditions. While most radio transients associated with galactic centers last only days or weeks, the galaxy SDSS J110546.07+145202.4 has been shining very brightly in radio light for several years—the first source of its kind.
