” We can, for the very first time, evaluate the result of the electromagnetic field in the gas flows toward [the central] star-forming areas using SOFIA and the galaxys center using radio polarimetric observations,” stated Enrique Lopez-Rodriguez, lead author on the recent paper describing NGC 1097s magnetic fields that was published in The Astrophysical Journal.
NGC 1097 has a region of extreme star development toward its center, understood as a starburst ring. Because looking at magnetic fields in really dense areas is among SOFIAs strengths, Lopez-Rodriguez and his team utilized SOFIA to probe the dense areas merging into the starburst ring. This was complemented by radio polarimetric observations within the starburst ring, a various kind of huge observation better fit for studying sparse areas.
The scientists found a striking difference in the morphology of the magnetic fields between the two areas. The SOFIA observations show the magnetic field feeding matter into the starburst ring, while the radio polarimetric observations show the magnetic field spiraling into the galaxys center, feeding the supermassive black hole.
In spite of this striking difference, the 2 are not totally disconnected: The research study shows that the magnetic fields in the galaxy assistance deliver gas and dust to the black hole at its. Entirely, the massive fields follow the shape of NGC 1097s spiral arms, directing matter from the arms to the starburst ring in its innermost areas, and from the starburst ring much deeper toward the black hole, where it can eat the material up.
This validates that it is not simply gravity that assists a black hole feed upon the product in its host galaxy, but magnetic fields likewise play a function.
” Our observations also provide proof that the magnetic fields found in the proximity of the black holes at the center of active galaxies may be originating from the massive magnetic field in the host galaxy,” Lopez-Rodriguez said.
This very first observation of electromagnetic fields nourishing great voids assists address vital concerns about how galaxies progress, and ultimately pass away.

SOFIA is a joint project of NASA and the German Space Agency at DLR. DLR supplies the telescope, set up aircraft maintenance, and other assistance for the objective. NASAs Ames Research Center in Californias Silicon Valley handles the SOFIA science, program, and mission operations in cooperation with the Universities Space Research Association, headquartered in Columbia, Maryland, and the German SOFIA Institute at the University of Stuttgart. The aircraft is preserved and run by NASAs Armstrong Flight Research Center Building 703, in Palmdale, California.
Due to the fact that looking at magnetic fields in really dense locations is one of SOFIAs strengths, Lopez-Rodriguez and his group used SOFIA to probe the thick areas merging into the starburst ring. In spite of this striking distinction, the 2 are not fully disconnected: The study shows that the magnetic fields in the galaxy assistance deliver gas and dust to the black hole at its.

A black hole at the center of a galaxy plays a function in the galaxys death, consuming up their surrounding dust and gas and not leaving sufficient matter behind for brand-new stars to form. Gravity alone, nevertheless, is not strong enough to represent all this product transfer on its own.
Theories have proposed that magnetic fields might be assisting gravity in feeding black holes, spooning matter in their direction. With the help of observations from the Stratospheric Observatory for Infrared Astronomy, or SOFIA, these theories have actually now been validated. By mapping out the shape of the electromagnetic fields in the main area of NGC 1097, a spiral nebula, researchers discovered the electromagnetic fields help in directing dust and gas toward the supermassive black hole at the galaxys center.
