Researchers Unveil Latest Images of Supermassive Black Holes Surrounded by Magnet Medang Page all

KOMPAS.com – Two years after producing the first image of black hole, the international research team has again released the latest sighting of the magnetic field around black holes.

This development says the researchers will bring them one step closer to understanding the galaxy Messier 87’s ability to launch jets from its core.

Previously, scientists Event Horizon Telescope captivated the world in April 2019, when they released black hole image supermassive at the center of the galaxy Messier 87, which is located 55 million light years from Earth.

The first polarized image of a black hole was the product of eight telescopes linked together around the world, to create a virtual telescope the size of the Earth, and worked years with complex techniques to acquire and analyze the data.

At that point, the researchers emphasized, that was just the beginning.

The dramatic image shows a dark central region outlined by a ring-like structure of light, which scientists at the time described as emission from hot gas swirling around it, under the influence of strong gravity near the event horizon, referring to the boundary marking it. the black hole.

The new image, meanwhile, captures the same look in polarized light, with streaks of brightly colored light that match its magnetic field.

“We now see the next important evidence for understanding how magnetic fields behave around black holes, and how activity in this highly dense region of space can propel powerful jets beyond galaxies,” said Monika Mo? Cibrodzka, coordinator of the EHT Polarimetry Working Group and a professor at Radboud University, Netherlands.

According to the EHT, bright jets of energy and matter emerge from the core of M87 and extend at least 5,000 light years from its center.

According to NPR, most of the material that lies near the edge of the black hole falls, but some of the surrounding particles manage to escape and are flung far into space in the form of jets – which is a process that has long intrigued researchers.

Astronomers are still working to understand how jets, larger than that galaxy, were launched from the black holes inside.

According to the researchers, the newly released black hole image and its shadow in polarized light allowed them to examine the activity-filled region outside the black hole for the first time.

“This work is an important milestone, as the polarization of light brings information that allows us to better understand the physics behind the images we saw in April 2019, which were not possible before,” said Iván Martí-Vidal, EHT coordinator. Polarimetry Working Group and researchers at University of Valencia Spanish.

Just as polarized sunglasses can help people see better by reducing reflections and glare, astronomers can sharpen their vision in the area around a black hole by seeing how light is coming from there (polarized).

With this new information, they can map the magnetic field lines on the inner edges of black holes to better understand their structure.

With these new findings, the research team is now referring to the role of highly magnetized gases.

Jason Dexter, koordinator EHT Theory Working Group and professors at University of Colorado Boulder, says, that new observations show that the magnetic field at the edge of a black hole is strong enough to push back the hot gas and help it resist the gravitational pull.

“Only the gas that escapes from the field can rotate inward to the event horizon,” said Dexter.

Dominic Pesce, a researcher at Harvard-Smithsonian Center for Astrophysics in Cambridge, Mass. says future observations will allow researchers to study how the structure of the magnetic field changes over time. Meanwhile, EHT itself will continue to grow.

“Even now we are designing the next generation of EHT that will allow us to make the first black hole film. So, stay tuned,” said Sheperd Doeleman, founding director of EHT.

Event Horizon Telescope said in the release that more than 300 researchers collaborated on the project and their findings have been published in two separate papers at The Astrophysical Journal.
