We present radio observations of a region in the vicinity of the young pulsar PSR B1853+01 in the supernova remnant W44. The pulsar is located at the apex of an extended feature with cometary morphology. We argue on the basis of its morphology and its spectral index and polarization properties that this is a synchrotron nebula produced by the spin-down energy of the pulsar. The geometry and physical parameters of this pulsar-powered nebula and W44 are used to derive three different measures of… 

Chandra observations of the pulsar wind nebula in SNR G0.9+0.1

We present observations with the Chandra X-Ray Observatory of the pulsar wind nebula (PWN) within the supernova remnant G0.9+0.1. At Chandra's high resolution, the PWN has a clear axial symmetry; a

The X-Ray Structure and Spectrum of the Pulsar Wind Nebula Surrounding PSR B1853+01 in W44

We present the result of a Chandra ACIS observation of the pulsar PSR B1853+01 and its associated pulsar wind nebula (PWN), embedded in the supernova remnant W44. A hard-band ACIS map cleanly

An Unusual Pulsar Wind Nebula Associated with PSR B0906–49

We report on Australia Telescope Compact Array observations of the ~105 yr old pulsar PSR B0906-49. In an image containing only off-pulse emission, we find a weak, slightly extended source coincident

A Radio Supernova Remnant Associated with the Young Pulsar J1119–6127

We report on Australia Telescope Compact Array observations in the direction of the young high magnetic-field pulsar J1119-6127. In the resulting images we identify a nonthermal radio shell of

A Multifrequency Radio Study of Supernova Remnant G292.0+1.8 and Its Pulsar Wind Nebula

We present a detailed radio study of the young supernova remnant (SNR) G292.0+1.8 and its associated pulsar PSR J1124-5916, using the Australia Telescope Compact Array at observing wavelengths of 20,

A Radio Survey for Pulsar Wind Nebulae

We have imaged the fields of 35 pulsars with the VLA at 8.4 GHz to search for evidence that the pulsars have deposited energy into their surroundings in the form of an extended wind nebula.

Chandra Imaging of the X-Ray Nebula Powered by Pulsar B1509–58

We present observations with the Chandra X-Ray Observatory of the pulsar wind nebula (PWN) powered by the energetic young pulsar B1509-58. These data confirm the complicated morphology of the system

The Location of Young Pulsar PSR J0837–2454: Galactic Halo or Local Supernova Remnant?

We present the discovery and timing of the young (age ∼28.6 kyr) pulsar PSR J0837–2454. Based on its high latitude (b = 98) and dispersion measure (DM = 143 pc cm−3), the pulsar appears to be at a

Chandra ACIS Spectroscopy of N157B: A Young Composite Supernova Remnant in a Superbubble

We present a Chandra ACIS observations of N157B, a young supernova remnant (SNR) located in the 30 Doradus star formation region of the Large Magellanic Cloud. This remnant contains the most

Radio Properties of Pulsar Wind Nebulae

Fast rotating neutron stars produce a steady energetic wind of relativistic particles and magnetic field that is released into the expanding ejecta of a core-collapse supernova explosion. This pulsar



Deep VLA Imaging of Pulsar-powered Nebulae and the Beaming Fraction of Young Pulsars

We have made sensitive, high-resolution images of the fields of seven pulsar-powered nebulae with the VLA at 20 and 6 cm. Our goal was to resolve out the extended emission from the nebula and to look

Discovery of a young, 267 millisecond pulsar in the supernova remnant W44

The discovery of a 267 ms pulsar, PSR 1853+01, in the supernova remnant W44 (G34.7−0.4) is reported. The pulsar is located south of the center of W44, well within its radio shell and at the southern

X-ray detection of the eclipsing millisecond pulsar PSR1957 +20

IN the binary millisecond pulsar system PSR1957 + 20 (ref. 1), a wind from the pulsar is ablating a low-mass (0.02 solar mass) companion and also inflating a local nebula2 confined by the ram

The X-ray-emitting trail of the nearby pulsar PSR1929 + 10

PULSARS—rapidly spinning, highly magnetized neutron stars—are thought to lose their rotational energy through the emission of relativistic particles1,2. As the typical lifetime of a pulsar greatly

Does the VELA Pulsar Have ``Wisps''?

VLA observations in the immediate vicinity of the Vela pulsar have been made using a technique to mask out the strong pulsed radio emission from the pulsar. The discovery of a localized ridge of

Confinement of the Crab pulsar's wind by its supernova remnant

We construct a steady state, spherically symmetric, magnetohydrodynamic model of the Crab nebual. A highly relativistic, positronic pulsar wind is terminated by a strong MHD shock that decelerates

Structure of relativistic shocks in pulsar winds: A model of the wisps in the Crab Nebula

We propose a model of a optical 'wisps' of the Crab Nebula, features observed in the nebular synchrotron surface brightness near the central pulsar, as manifestations of the internal structure of the

Pulsars, X-ray synchrotron nebulae, and guest stars

X-ray observations of supernova remnants and radio pulsars are used to derive luminosities of neutron stars and synchrotron nebulae. Observations of known isolated pulsars are used to develop an
