Using the EXIST Active Shields for Earth Occultation Observations of X-ray Sources
Colleen A. Wilson, G. J. Fishman, J. -S. Hong +2
The EXIST active shields, planned for the main detectors of the coded aperture telescope, will have approximately 15 times the area of the BATSE detectors, and they will have a goo…
Search for TeV Emission at the Location of Milagro Sky Survey Hot Spot Using the Whipple Gamma-Ray Telescope
A. Falcone
A recent report from the Milagro collaboration included an all-sky map created using one year of data from Milagro (peak sensitivity at 3-4 TeV for Crab-like spectra). This map inc…
Search for Very High Energy Gamma Rays from an X-ray Selected Blazar Sample
I. de la Calle Perez
In recent years, blazar surveys at radio and X-ray energies have greatly increased our understanding of this type of active galaxy. The combination of multi-wavelength data has sho…
Pressure Balance between Thermal and Non-Thermal Plasmas in the 3C129 Cluster
D. E. Harris, H. Krawczynski
With new Chandra observations of the cluster containing the two radio galaxies 3C129 and 3C129.1, we have made a fit to the X-ray surface brightness to obtain thermal pressures. VL…
Spectroscopic Deprojection-Analysis of 3C 129
Henric Krawczynski
We report on spectroscopic imaging observations of the nearby (z=0.022) galaxy cluster 3C 129 performed with the ACIS detector on board of the Chandra X-ray observatory. Applying a…
X-ray/TeV-gamma-ray observations of several strong flares of Mkn 501 during 1997 and implications
H. Krawczynski, P. S. Coppi, T. Maccarone +1
During more than 6 months in 1997, the BL Lac object Mkn 501 was in an exceptionally bright state, both in the X-ray band and in the Very High Energy (VHE) band. In this paper we p…
