NASA's Swift Helps Tie Neutrino to Star-shredding Black Hole

For only the second time, astronomers have linked an elusive particle called a high-energy neutrino to an object outside our galaxy. Using ground- and space-based facilities, including NASA's Neil Gehrels Swift Observatory, they traced the neutrino to a black hole tearing apart a star, a rare cataclysmic occurrence called a tidal disruption event.

NASA Missions Unmask Magnetar Eruptions in Nearby Galaxies

On April 15, 2020, a brief burst of high-energy light swept through the solar system, triggering instruments on several NASA and European spacecraft. Now, multiple international science teams conclude that the blast came from a supermagnetized stellar remnant known as a magnetar located in a neighboring galaxy.

NASA Missions Help Pinpoint the Source of a Unique X-ray, Radio Burst

On April 28, a supermagnetized stellar remnant known as a magnetar blasted out a simultaneous mix of X-ray and radio signals never observed before. The flare-up included the first fast radio burst (FRB) ever seen from within our Milky Way galaxy and shows that magnetars can produce these mysterious and powerful radio blasts previously only seen in other galaxies.

After-Flare Detected from Black Hole Dance

Astronomers have used NASA's telescopes, including the Neil Gehrels Swift observatory, to observe one of the largest black hole known, named OJ 287. OJ287 is a blazar hosting a black hole with the mass 18 billion times that of the Sun, and orbited by a smaller companion black hole, "only'' 150 million times more massive than the Sun. The pair of black holes has been monitored since late 2015 with NASA's Swift satellite and in a recently published paper a team of astronomers report a flash of ultraviolet and X-ray radiation. These observations provides a unique laboratory to study black hole feeding, jet formation, and general relativity.
