Telescopes team up for dramatic new look at the crab nebula
Telescopes dramatic crab nebula
2017/7/20
Astronomers produced this dramatic new, highly-detailed image of the Crab Nebula by combining data from telescopes spanning nearly the entire breadth of the electromagnetic spectrum, from the long wav...
Chandra Observation of Supernova Remnant G54.1+0.3: A Close Cousin of the Crab Nebula
G54.1+0.3 jets and outfl ows
2014/12/26
We present a Chandra Advanced CCD Imaging Spectrometer observation of supernova remnant G54.1+0.3. This supernova remnant is resolved into several distinct X-ray-emitting components: a central bright ...
MAXI GSC monitoring of the Crab nebula and pulsar during the GeV gamma-ray flare in September 2010
stars: neutron — stars: pulsars: individual (Crab) — X-rays: indi- vidual
2011/10/12
We report on the MAXI GSC X-ray monitoring of the Crab nebula and pulsar during the GeV gamma-ray flare for the period of 2010 September 18-24 (MJD 55457-55463) detected by AGILE and Fermi-LAT. There ...
VLBI imaging of a flare in the Crab Nebula: More than just a spot
ISM:supernova remnants —radio continuum:stars— pulsars:general —pulsars:individual:Crab pulsar
2011/9/26
We report on very long baseline interferometry (VLBI) observations of the radio emission from the inner region of the Crab Nebula, made at 1.6 GHz and 5 GHz after a recent high-energy flare in this ob...
On the origin of variable gamma-ray emission from the Crab Nebula
ISM supernova remnants MHD shock waves gamma-rays theory radiation mechanisms non-thermal
2010/11/12
The oblique geometry of pulsar wind termination shock ensures that the Doppler beaming has a strong impact on the shock emission. We illustrate this using recent relativistic MHD simulations of the Cr...
