Like most celestial objects, pulsars have poles, and when they’re faced towards Earth, we can see the rotating light pulses these mysterious objects emit, hence their given name. The first pulsar was discovered by Professor Dame Jocelyn Bell in 1967 when she was a PhD student at the Univers...
Several long-period radio transients have recently been discovered, with strongly polarized coherent radio pulses appearing on timescales between tens to thousands of seconds1,2. In some cases, the radio pulses have been interpreted as coming from rotati
pulsars: individual: Crab pulsarThe Crab pulsar is well-known for its anomalous giant radio pulse emission. Past studies have concentrated only on the very bright pulses or were insensitive to the faint end of the giant pulse luminosity distribution. With our new instrumentation offering a large ...
We find that the conventional two-pole caustic model fails to produce double-peak pulse profiles, mainly because the size of the polar cap in force-... XN Bai,A Spitkovsky - 《Astrophysical Journal》 被引量: 116发表: 2010年 Chandra Phase-resolved X-Ray Spectroscopy of the Crab Pulsar Ana...
Using seven radio telescopes in Australia, the US and Europe, the researchers monitored the double pulsar system between its discovery in 2003 until 2019. They found that the radio pulses consistently arrived later than expected, and calculated this was because they were being deflected...

Ahora puedes pulsar el botón verde 'Selecciona imágenes a subir', cuando pulses este botón podrás subir tus imágenes, Yo lo probé con 64 imágenes pero puede que sean más, una vez seleccionadas todas las imágenes aparecerán en la pantalla, espera a que se carguen todas. Step four ...
This has not hitherto been possible because glitch events happen unpredictably. Here we report single-pulse radio observations of a glitch in the Vela pulsar, which has a rotation frequency of 11.2hertz. The glitch was detected on 2016 December 12 at 11:36 universal time, during continuous ...
magnetic fields send out beams of gamma rays, the most energetic form of light. As these beams sweep across the Earth, the highly sensitive Fermi gamma-ray telescope can observe their periodic pulses of energy. With more than 15 years of data, Fermi has transformed the field ofpulsarresearch...
It’s not the particles that move outwards but the pulses of light giving the misleading appearance of a “jet”. A pulsar, a star that rapidly pulsates, is very probably a “black hole” as seen from an exact polar perspective. A universe-wide electric network There are strong ...
