The extended emission of the Vela PWN in the 3–10 keV band that we can see in Fig. 1 softens at growing distances from the pulsar: the photon index value passes from ± to ± as the radius increases from 0′.5 to 15′. High energy emission from the source, detected by the PDS (15– keV), originates from an extended Cited by: 1. N2 - We report on gamma-ray observations in the off-pulse window of the Vela pulsar PSR B using 11 months of survey data from the Fermi Large Area Telescope (LAT). This pulsar is located in the 8° diameter Vela supernova remnant, which contains several regions of non-thermal emission detected in the radio, X-ray, and gamma-ray by:

Characteristics. Vela is the brightest pulsar (at radio frequencies) in the sky and spins times per second (i.e. a period of milliseconds—the shortest known at the time of its discovery) and the remnant from the supernova explosion is estimated to be travelling outwards at 1, km/s ( mi/s).
It has the third-brightest optical component of all known pulsars (V = Constellation: Vela. This collection of original papers on the special and general theories of relativity is an unabridged translation of the 4th edition of Das Relativitatsprinzip, together with a revised edition of an additional paper by H.

Mumford. Explanation: The Vela pulsar is a neutron star born o years ago in a massive supernova explosion. Above, false-color x-ray images from the Chandra Observatory reveal details of this remnant pulsar's x-ray bright nebula along with emission from a spectacular jet of high-energy particles.

Pulsars exhibit a periodic emission of possibly ms time scale. Inthe H.E.S.S. experiment reported the detection down to 20 GeV of gamma rays from the Vela pulsar having a periodicity of 89 ms. Using a likelihood analysis, calibrated with a dedicated Monte-Carlo procedure, we obtain the first limit on QG energy scale with the Vela pulsar.
We have studied the fascinating dynamics of the nearby Vela pulsar's nebula in a campaign comprising eleven 40ks observations with Chandra X-ray Observatory (CXO). The deepest yet images revealed the shape, structure, and motion of the 2-arcminute-long pulsar jet. We find that the jet's shape and dynamics are remarkably consistent with that of a steadily Cited by: In the book Decoding the Message of the Pulsars, from more than known pulsars a half dozen pulsars were singled out as possibly conveying an intelligent of these are the Crab pulsar, the Vela pulsar, and the Vulpecula pulsar, whose periods and period derivatives are listed in the table below.

Other articles where Vela pulsar is discussed: pulsar: Pulsars in visible light, X-rays, and gamma rays: such as the Crab and Vela pulsars, are losing rotational energy so precipitously that they also emit radiation of shorter wavelength.
The Crab Pulsar appears in optical photographs as a moderately bright (magnitude 16) star in the centre of the Crab Nebula.
Single-pulse radio observations of a glitch in the Vela pulsar show sudden changes in the pulse shape coincident with the glitch, indicating that the glitch could affect the pulsar’s by: Pulsar. A neutron star that emits rapid and periodic pulses of radiation.
A neutron star is an extremely compact ball of neutrons created from the central core of a star that collapsed under gravity during a supernova explosion.
Neutron stars are extremely dense: they are only 10 kilometers or so in size, but have the mass of an average star. Fundamentals of Jet Propulsion with Applications is an introductory text in air-breathing jet propulsion including ramjets, turbojets, turbofans, and propjets.
Aimed at upper-level undergraduate and graduate students, the book provides coverage of the basic operating principles, from cycle analysis through component design and system matching/5(7).

Pulsar timing arrays monitor millisecond pulsars in the Milky Way. As a pulsar rotates, it emits radio waves that sweep by Earth with the period of rotation.
The shorter the period, the more and sharper the incident radio-wave ticks, so the better the clock. A gravitational wave passing between a pulsar clock and an observer distorts spacetime Cited by: 3.
Pion condensates can help to explain a variety of physical properties owned by pulsars if they are present in their interiors. It has been noted that they offer, for example, an attractive alternative to understand glitches by improving former core-quake models. We discuss this scenario and show in this work some constraints on the properties of this type of matter Author: J.

Some of the most exciting discoveries and their impact on our understanding of radio pulsars are discussed as well as speculations for the : D. R. Lorimer. Pulsars rotate at very stable speeds, but slow down as they emit radiation and lose their energy. Professor Nils Andersson and Dr Wynn Ho, from the University of Southampton, have now found a way to predict how this ‘slowing’ process will develop in individual pulsars
