A radio and optical view of galaxy NGC 5643 shows the fiery core of a luminous Seyfert galaxy, powered by gas and debris being sucked into a supermassive black hole hidden by vast clouds of dust and debris. It is difficult to probe the shrouded inner regions of a Seyfert galaxy, but researchers using the Atacama Large Millimetre/submillimetre Array – ALMA – and the Multi Unit Spectroscopic Explorer – MUSE – on the Very Large Telescope have captured this view of electrically charged gas being ejected from the black hole’s accretion disk to either side of the core. Cold molecular gas traced by carbon monoxide, seen in red, defines the galaxy’s rotating inner region.
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have discovered an adolescent protostar that is undergoing a rapid-fire succession of growth spurts. Evidence for this fitful youth is seen in a pair of intermittent jets streaming away from the star’s poles. Known as CARMA-7, the protostar is one of dozens of similar objects in the Serpens South star cluster, which is located approximately 1,400 light-years from Earth.
