Electron Acceleration and Synchrotron Radiation in Decelerating Plasmoids
Charles D. Dermer, James Chiang
An equation is derived to calculate the dynamics of relativistic magnetized plasma which decelerates by sweeping up matter from the ISM. Reduction to the non-radiative and radiativ…
A Multiwavelength Investigation of the Relationship Between 2CG135+1 and LSI+61o 303
M. S. Strickman, M. Tavani, M. J. Coe +5
We present the results of a multiwavelength monitoring campaign targeting the gamma-ray source 2CG 135+1 in an attempt to confirm the association of this object with the radio/Be/X…
Multiwavelength Observations of a Dramatic High Energy Flare in the Blazar 3C 279
A. E. Wehrle, E. Pian, C. M. Urry +3
The blazar 3C 279, one of the brightest identified extragalactic objects in the gamma-ray sky, underwent a flare of a factor 10 amplitude in gamma-rays towards the end of a 3-week…
High Energy Break and Reflection Features in the Seyfert Galaxy MCG+8-11-11
P. Grandi, F. Haardt, G. Ghisellini +3
We present the results from ASCA and OSSE simultaneous observations of the Seyfert 1.5 galaxy MCG+8-11-11 performed in August-September 1995. The ASCA observations indicate a modes…
The Radial Extent and Warp of the Ionized Galactic Disk. I. A VLBA Survey of Extragalactic Sources Toward the Anticenter
T. Joseph W. Lazio, James M. Cordes
We report multifrequency Very Long Baseline Array observations of twelve active galactic nuclei seen toward the Galactic anticenter. All of the sources are at |b| < 10 degrees and…
The Radial Extent and Warp of the Ionized Galactic Disk. II. A Likelihood Analysis of Radio-Wave Scattering Toward the Anticenter
T. Joseph W. Lazio, James M. Cordes
We use radio-wave scattering data to constrain the distribution of ionized gas in the outer Galaxy. Like previous models, our model for the H II disk includes parameters for the ra…
