A Multiwavelength Investigation of Unidentified EGRET Sources
P. M. Wallace, S. D. Bloom, M. S. Lewis
Statistical studies indicate that the 271 point sources of high-energy gamma rays belong to two groups: a Galactic population and an isotropic extragalactic population. Many uniden…
Multi-Epoch VLBA Observations of EGRET-Detected Quasars and BL Lac Objects: Connection between Superluminal Ejections and Gamma-Ray Flares in Blazars
Svetlana G. Jorstad, Alan P. Marscher, John R. Mattox +4
We examine the coincidence of times of high -ray flux and ejections of superluminal components from the core in EGRET blazars based on a VLBA monitoring program at 22 and 43 GHz…
Multi-Epoch VLBA Observations of EGRET-Detected Quasars and BL Lac Objects: Superluminal Motion of Gamma-Ray Bright Blazars
Svetlana G. Jorstad, Alan P. Marscher, John R. Mattox +3
We present the results of a program to monitor the structure of the radio emission in 42 -ray bright blazars (31 quasars and 11 BL Lac objects) with the VLBA at 43, 22, and occa…
A Systematic Search for Short-term Variability of EGRET Sources
P. M. Wallace, D. L. Bertsch, S. D. Bloom +4
The 3rd EGRET Catalog of High-energy Gamma-ray Sources contains 170 unidentified sources, and there is great interest in the nature of these sources. One means of determining sourc…
EGRET Spectral Index and the Low-Energy Peak Position in the Spectral Energy Distribution of EGRET-Detected Blazars
Y. C. Lin
In current theoretical models of the blazar subclass of active galaxies, the broadband emission consists of two components: a low-frequency synchrotron component with a peak in the…
Multiwaveband Observations of Quasars with Flat Radio Spectra and Strong Millimeter Emission
S. D. Bloom, A. P. Marscher, E. M. Moore +5
We present multiwaveband observations of a well selected sample of 28 quasars and two radio galaxies with flat radio spectra and strong millimeter wave emission (referred to here a…
Analyzing the Multiwavelength Spectrum and Variability of BL Lacertae During the July 1997 Outburst
M. Boettcher, S. D. Bloom
The multiwavelength spectrum of BL Lacertae during its July 1997 outburst is analyzed in terms of different variations of the homogeneous leptonic jet model for the production of h…
Possible New Identifications for EGRET Sources
S. D. Bloom, R. C. Hartman, H. Terasranta +2
We have conducted a multiwavelength study of several radio sources within or near the error boxes of EGRET unidentified sources at mid to high Galactic latitude, under the hypothes…
Observations of a Correlated Gamma-Ray and Optical Flare for BL Lacertae
S. D. Bloom
The latest observations of BL Lacertae with the EGRET instrument on CGRO show that the gamma-ray flux was four times higher than the previous detection. Within the 1997 July 15-22…
