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
Joseph D. Gelfand, B. M. Gaensler
We present X-ray, infrared and radio observations of the field centered on X-ray source 1E 1547.0-5408 in the Galactic Plane. A new Chandra observation of this source shows it is u…
The Radio Emission, X-ray Emission, and Hydrodynamics of G328.4+0.2: A Comprehensive Analysis of a Luminous Pulsar Wind Nebula, its Neutron Star, and the Progenitor Supernova Explosion
Joseph D. Gelfand, B. M. Gaensler, Patrick O. Slane +3
We present new observational results obtained for the Galactic non-thermal radio source G328.4+0.2 to determine both if this source is a pulsar wind nebula or supernova remnant, an…
Can Ejecta-Dominated Supernova Remnants be Typed from their X-ray Spectra? The Case of G337.2-0.7
Cara E. Rakowski, Carles Badenes, B. M. Gaensler +3
In this paper we use recent X-ray and radio observations of the ejecta-rich Galactic supernova remnant (SNR) G337.2-0.7 to determine properties of the supernova (SN) explosion that…
A Wide Field, Low Frequency Radio Image of the Field of M31: II. -- Source Classification and Discussion
Joseph D. Gelfand, T. J. W. Lazio, B. M. Gaensler
We have previously presented the results of a 325 MHz radio survey of M31, conducted with the A-configuration of the Very Large Array. In this survey, a total of 405 radio sources…
The Growth, Polarization, and Motion of the Radio Afterglow from the Giant Flare from SGR 1806-20
G. B. Taylor, J. D. Gelfand, B. M. Gaensler +8
The extraordinary giant flare (GF) of 2004 December 27 from the soft gamma repeater (SGR) 1806-20 was followed by a bright radio afterglow. We present an analysis of VLA observatio…
Two New X-ray/Optical/Radio Supernova Remnants in M31
B. F. Williams, L. O. Sjouwerman, A. K. H. Kong +3
We compare a deep (37 ks) Chandra ACIS-S image of the M31 bulge to Local Group Survey narrow-band optical data and Very Large Array (VLA) radio data of the same region. Our precise…
