The Radio to Gamma Ray Connection of EGRET Blazars: Correlation, Regression and Monte Carlo Analysis
S. D. Bloom
A comprehensive statistical analysis of the broadband properties of EGRET blazars is presented. This analysis includes sources identified as blazars in the Sowards-Emmerd publicati…
A Near-Infrared and X-ray Study of W49B: A Wind Cavity Explosion
Jonathan W. Keohane, William T. Reach, Jeonghee Rho +1
We present near-infrared narrow-band images of the supernova remnant W49B, taken with the WIRC instrument on the Hale 200 inch telescope on Mt. Palomar. The 1.64 micron [Fe II] ima…
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…
The WEBT BL Lacertae Campaign 2001 and its extension
M. Villata, C. M. Raiteri
BL Lacertae has been the target of four observing campaigns by the Whole Earth Blazar Telescope (WEBT) collaboration. In this paper we present light curves obtained by the…
An Optical Survey of the Position Error Contours of Unidentified High Energy Gamma-Ray Sources at Galactic Latitude b >|20| degrees
S. D. Bloom, D. A. Dale, R. Cool +7
We present the most recent results of an optical survey of the position error contours ("error boxes") of unidentified high energy gamma-ray sources.
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 Multiwavelength Spectra and Models for Blazar 3C~279
R. C. Hartman, M. Boettcher
Of the blazars detected by EGRET in GeV gamma rays, 3C 279 is not only the best-observed by EGRET, but also one of the best-monitored at lower frequencies. We have assembled eleven…
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…
Gamma Radiation from PSR B1055-52
D. J. Thompson
The telescopes on the Compton Gamma Ray Observatory (CGRO) have observed PSR B1055-52 a number of times between 1991 and 1998. From these data, a more detailed picture of the gamma…
EGRET Observations of the Extragalactic Gamma Ray Emission
P. Sreekumar
The all-sky survey in high-energy gamma rays (E30 MeV) carried out by the Energetic Gamma Ray Experiment Telescope (EGRET) aboard the Compton Gamma-Ray Observatory provides a un…
Multi-wavelength Observations of 3C 273 in 1993-1995
C. von Montigny
We present the results of the multi-wavelength campaigns on 3C 273 in 1993-1995. During the observations in late 1993 this quasar showed an increase of its flux for energies greate…
