Magnetic fields encompass Milky Way’s black gap: Observatory

There are robust magnetic fields across the black gap within the heart of the Milky Way galaxy, astronomers on the European Southern Observatory mentioned Wednesday.

A brand new picture from the Event Horizon Telescope (EHT) for the primary time confirmed a hoop of magnetic fields surrounding the Sagittarius A* black gap in polarized mild.

The fields are just like these noticed across the M87* black gap on the coronary heart of the M87 Galaxy, which the ESO says means that robust magnetic fields could also be widespread to all black holes.

“What we’re seeing now is that there are strong, twisted and organized magnetic fields near the black hole at the center of the Milky Way galaxy,” mentioned Sara Issaoun, from Harvard’s Center for Astrophysics and co-lead of the challenge.

Polarized mild photographs permit the astronomers to isolate the magnetic discipline traces.

Supermassive black holes, which sit on the heart of galaxies, have plenty thousands and thousands and even billions better than the Sun. They are believed to have emerged very early within the universe, however their creation stays a thriller.

Nothing can escape their gravitational pull, not even mild, making them not possible to watch immediately.

But with M87* in 2019 and Sagittarius A* in 2022, the EHT captured the halo of sunshine that’s produced by the move of matter and fuel that black holes suck in and eject.

“By imaging polarized light from hot glowing gas near black holes, we are directly inferring the structure and strength of the magnetic fields that thread the flow of gas and matter that the black hole feeds on,” mentioned Angelo Ricarte, a member of the Harvard Black Hole Initiative and a co-lead of the challenge.

Mariafelicia De Laurentis, deputy scientist on the EHT and professor on the University of Naples Federico II in Italy, mentioned that “since both (black holes) are pointing us toward strong magnetic fields, it suggests that this may be a universal and perhaps fundamental feature of these kinds of systems.”
