A new NASA telescope will observe the most energetic objects in our galaxy


Sivakoff said: “It turns out that you can only measure three things about the properties of a black hole: its mass, its spin, and its charge.” “I am very interested in IXPE’s ability to provide us with a new method of measuring rotation. Very interested, maybe even check if there is any change in the rotation in a long enough time.”

Black holes account for about 40% of the dark matter in the universe, but it’s only recently that astronomers have been able to A photoThe data that IXPE will bring back will help determine Once active black hole Their Neighbor And make it easier for scientists to study the particles that exist around these powerful objects. With the help of X-ray polarization, the inner edge of a black hole can also be drawn by measuring angular momentum or spin.

Sivakoff added that because supermassive black holes and neutron stars are remnants of massive stars, they live fast and die very early. The IXPE mission can also give us a glimpse of how galaxies have evolved.

Herman MarshallA research scientist at the Cavley Institute for Astrophysics and Space at MIT and a joint researcher at IXPE said that measuring polarization “is like installing a mirror in an invisible part of the Milky Way, you might say.” Hopefully once IXPE will Turn your eyes to the stars, and the Milky Way will not mind revealing some more secrets.
