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 ...
"The emission, which resembles a lighthouse beam, repeatedly sweeps past Earth as the star rotates," Mikhail Medvedev, lead author of the research, said in a statement. "We observe this as a pulsed ...
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 ...
