Crab Nebula’s pulsar exhibits unique zebra-like radiation patterns. Plasma diffraction identified as the cause of the unusual emission. Study unlocks new methods for understanding young neutron stars.

A theoretical astrophysicist may have solved a nearly two-decade-old mystery over the origins of an unusual 'zebra' pattern seen in high-frequency radio pulses from the Crab Nebula. A theoretical ...

A pulsar's radiation is getting refracted by plasma in the magnetosphere. Historical records from around the world describe a bright star appearing in the sky in the year 1054. Today, astronomers ...

After two decades of curiosity, researchers now know what causes the unique “zebra” pattern in the Crab Nebula’s signals. A spinning neutron star, or pulsar, at the nebula’s center creates the striped ...

The Crab Nebula is a supernova remnant that contains a neutron star at its core, which has condensed into a pulsar. This pulsar, only 12 miles wide, spins rapidly and emits beams of electromagnetic ...

His findings have just been published in Physical Review Letters. The Crab Nebula features a neutron star at its center that has formed into a 12-mile-wide pulsar pinwheeling electromagnetic ...

But this wasn't just any supernova. It was a supernova that would eventually lead to the formation of the Crab Nebula — a collage of interstellar gas and dust illuminated by the energy expelled ...

A long-standing enigma surrounding the Crab Pulsar, a neutron star at the center of the Crab Nebula, may have been unraveled by a theoretical astrophysicist from the University of Kansas. The study, ...

But this wasn't just any supernova. It was a supernova that would eventually lead to the formation of the Crab Nebula — a collage of interstellar gas and dust illuminated by the energy expelled during ...

Medvedev modeled wave diffraction off a circular reflecting region with radially varying index of refraction outside of it to better understand the Crab Nebula’s zebra pattern. LAWRENCE — A ...

Over 2 decades of Chandra X-ray Observatory views of the Crab Nebula and Cassiopeia A have been time-lapsed. The Chandra team explains here. Credit: NASA/CXC/A. Hobart ...

A theoretical astrophysicist from the University of Kansas, Mikhail Medvedev, has potentially solved a nearly two-decade-old mystery regarding the “zebra” pattern seen in high-frequency radio pulses ...
