The evolution and structure of pulsar wind nebulae
AbstractPulsars steadily dissipate their rotational energy via relativistic winds. Confinement of these outflows generates luminous pulsar wind nebulae, seen across the electromagnetic spectrum in ...
The Vertical Structure of Warm Ionised Gas in the Milky Way
Abstract We present a new joint analysis of pulsar dispersion measures and diffuse Hα emission in the Milky Way, which we use to derive the density, pressure and filling factor of the thick diskExpand
Nonthermal X-Ray Emission from the Shell-Type Supernova Remnant G347.3-0.5
Recent ASCA observations of G347.3-0.5, a supernova remnant (SNR) discovered in the ROSAT All-Sky Survey, reveal nonthermal emission from a region along the northwestern shell. Here we report on newExpand
Discovery of 35 New Supernova Remnants in the Inner Galaxy
We report the discovery of up to 35 new supernova remnants (SNRs) from a 42'' resolution, 90 cm multiconfiguration Very Large Array survey of the Galactic plane covering 45 < l < 220 and b < 125.Expand
A model of diffuse Galactic radio emission from 10 MHz to 100 GHz
Understanding diffuse Galactic radio emission is interesting both in its own right and for minimizing foreground contamination of cosmological measurements. cosmic microwave background experimentsExpand
Dynamical Formation of Close Binary Systems in Globular Clusters
We know from observations that globular clusters are very efficient catalysts in forming unusual short-period binary systems or their offspring, such as low-mass X-ray binaries (LMXBs; neutron starsExpand
The Compact X-Ray Source 1E 1547.0–5408 and the Radio Shell G327.24-0.13: A New Proposed Association between a Candidate Magnetar and a Candidate Supernova Remnant
We present X-ray, infrared and radio observations of the field centered on X-ray source 1E 1547.0–5408 in the Galactic Plane. Analysis of a new Chandra observation of this source shows it isExpand
A giant γ-ray flare from the magnetar SGR 1806–20
Two classes of rotating neutron stars—soft γ-ray repeaters (SGRs) and anomalous X-ray pulsars—are magnetars, whose X-ray emission is powered by a very strong magnetic field (B ≈ 1015 G). SGRsExpand
wsclean: an implementation of a fast, generic wide-field imager for radio astronomy
Astronomical widefield imaging of interferometric radio data is computationally expensive, especially for the large data volumes created by modern non-coplanar many-element arrays. We present a newExpand
The Southern Galactic Plane Survey: H I Observations and Analysis
We describe the H I component of the Southern Galactic Plane Survey (SGPS). The SGPS is a large-scale project to image at arcminute resolution the H I spectral line and 21 cm continuum emission inExpand
