Strange 'zebra' patterns are coming from the Crab Nebula — this physicist finally figured out why
Historical records from around the world describe a bright star appearing in the sky in the year 1054. Today, astronomers are confident that what our ancestors were seeing was, in truth, a star that ...
Most pulsar radio emissions are spectrally broader and noisy — not banded so cleanly like the Crab Pulsar. An NASA image of the Crab Nebula seen by the James Webb Space Telescope. LAWRENCE — For the ...
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 ...
