Scientists may have discovered a pulsar at the Milky Way's hearta result that could reveal new physics

"At the center of the Milky Way, there might lie a pulsara highly magnetized, spinning neutron star that formed from the dead husk of a massive star that had gone supernova. If confirmed, the possible discovery, which was announced in a paper published on Monday, could reveal new physics. Pulsars are the universe's lighthouses. As they spin, they emit steady and predictable bursts of radiation. In turn, researchers can use these rhythmic pulses to reveal tiny changes in spacetime and detect gravitational waves caused by large, massive objectsincluding supermassive black holes."

"The discovery of a pulsar near the Milky Way's central supermassive black hole, Sagittarius A*, could prove invaluable to astronomers as they seek to understand this cosmic behemoth, according to the researchers behind the possible finding. Any external influence on a pulsar, such as the gravitational pull of a massive object, would introduce anomalies in this steady arrival of pulses, which can be measured and modeled, said Slavko Bogdanov, an associate research scientist at Columbia University and a co-author of the study, in a statement."

A pulsar may lie at the center of the Milky Way, representing a highly magnetized, spinning neutron star formed after a supernova. Such a pulsar could reveal new physics by serving as an extremely regular timing source. Pulsars emit steady, predictable bursts of radiation that can be used to detect tiny changes in spacetime and to sense gravitational waves produced by large, massive objects, including supermassive black holes. A pulsar located near Sagittarius A* would allow measurement of anomalies in pulse arrival times caused by external gravitational influences, and those anomalies can be modeled to probe the black hole's spacetime.
