Massive and unknown radio structure detected around the brightest quasar in the universe

Astronomers have discovered two large mysterious objects erupting from the brightest black hole in the known universe. Discovered during a 1959 survey of the cosmos radio wave sources, the supermassive black hole 3C 273 is a quasar – short for “quasi-stellar object”, because the light emitted by these behemoths is bright enough to be mistaken …

Giant Galaxy With a High-Energy Jet

High-contrast imagery reveals an unknown structure in the galaxy

Artist’s impression of a giant galaxy with a high-energy jet. Credit: ALMA (ESO/NAOJ/NRAO) Astronomers have just discovered an unknown structure in a galaxy that had been hidden in the “shadows”. They achieved this by extending the dynamic range of the Atacama Large Millimeter/submillimeter Array ([{” attribute=””>ALMA), the largest astronomical project in existence, in order to …

Unknown structure in the galaxy revealed by high-contrast imagery

Artist’s impression of a giant galaxy with a high-energy jet. Credit: ALMA (ESO/NAOJ/NRAO) With high dynamic range imaging, a team of astronomers in Japan discovered for the first time a faint radio emission covering a giant galaxy with an energetic black hole at its center. The radio emission comes from the gas created directly by …

Strange ‘unknown structure’, faint radio glow thousands of light-years wide, found around nearest quasar

A new technique for studying some of the brightest objects in the universe has upended scientists’ understanding of the link between active monster black holes and suppressed star formation. Quasars are the ultra-luminous nuclei of galaxies that contain supermassive black holes. The intense radiation from a quasar comes from massive amounts of hot gas forming …
