The Full Spectrum Galactic Terrarium: MHz to TeV Observations of Various Critters
Mallory S. E. Roberts, C. Brogan, S. Ransom +13
Multi-wavelength studies at radio, infrared, optical, X-ray, and TeV wavelengths have discovered probable counterparts to many Galactic sources of GeV emission detected by EGRET. T…
Discovery of a New X-ray Filled Radio Supernova Remnant Around the Pulsar Wind Nebula in 3EG J1809-2328
Mallory S. E. Roberts, Crystal L. Brogan
We report the discovery of a partial ~2deg. diameter non-thermal radio shell coincident with Taz, the pulsar wind nebula (PWN) in the error box of the apparently variable gamma-ray…
The GBT350 Survey of the Northern Galactic Plane for Radio Pulsars and Transients
J. W. T. Hessels, S. M. Ransom, V. M. Kaspi +3
Using the Green Bank Telescope (GBT) and Pulsar Spigot at 350MHz, we have surveyed the Northern Galactic Plane for pulsars and radio transients. This survey covers roughly 1000 squ…
The Unusual Binary Pulsar PSR J1744-3922: Radio Flux Variability, Near-infrared Observation and Evolution
R. P. Breton, M. S. E. Roberts, S. M. Ransom +4
PSR J1744-3922 is a binary pulsar exhibiting highly variable pulsed radio emission. We report on a statistical multi-frequency study of the pulsed radio flux variability which sugg…
Runaway Massive Binaries and Cluster Ejection Scenarios
M. Virginia McSwain, Scott M. Ransom, Tabetha S. Boyajian +2
The production of runaway massive binaries offers key insights into the evolution of close binary stars and open clusters. The stars HD 14633 and HD 15137 are rare examples of such…
Recent Observations of EGRET Pulsar Wind Nebulae
Mallory S. E. Roberts, E. V. Gotthelf, Jules P. Halpern +2
We present recent X-ray and radio observations of pulsar wind nebulae discovered in EGRET error boxes. Two XMM-Newton observations show the X-ray extent of the rapidly moving PWN a…
