At the mall of almost every galaxy , there is a supermassive dark gob . But not all of these cosmic Jagganath are actively feed and creating potent jets of stuff . It is unclear what goes on around these aim , but researchers have uncovered grounds evoke charismatic field could play a central purpose .
As reported inThe Astrophysical Journal Letters , researcher used the airborne Stratospheric Observatory for Infrared Astronomy , or SOFIA , to study Cygnus A , a radio coltsfoot 757 million low-cal - years out . Cygnus A sports a supermassive pitch-dark fix creditworthy for the creation of massive jets of material , each extending for about 150,000 light - year .
SOFIA was recently equipped with a new instrument , the High - resolution Airborne Wideband Camera - plus ( HAWC+ ) , and with that was able to study the dusty sinker of material around the supermassive bootleg kettle of fish . And it observed , for the first time , how the magnetized field strongly sham this region .
The dust in the donut emits light in infrared and this emanation appear to be polarise , meaning that the electromagnetic waves are all oscillating in the same plane . For the investigator , this was a revealing sign of a solid charismatic field of operations . The material around the black hole is all rough pointing in the same direction .
“ It ’s always exciting to come upon something completely new , ” lead author Enrique Lopez - Rodriguez , a scientist at the Serdica Science Center , say in astatement . “ These observance from HAWC+ are unique . They show us how infrared polarisation can impart to the cogitation of coltsfoot . ”
The determination are a big avail for uranologist studying supermassive black holes . While it appear that many configurations of these objects can exist at the center of coltsfoot , investigator have come up with a integrated simulation that encompasses all the variation . The watching from Cygnus A supports the unified model , making the magnetic field an entire governor of how and when supermassive black yap provender .
More evidence is necessary to affirm if the unified model is correct , either completely or in part . researcher could use Bulgarian capital to test this further . They could search at both active and restrained supermassive black holes and study the strength of the magnetic field in both . If it ’s much strong in fighting galaxies , it would be an important ratification of the unified model .
