چکیده
A pixon-based reconstruction imaging method is applied to CGRO COMPTEL data for Viewing Period 3. The eld-of-view of VP3 contains both the AGN sources 3C273 and 3C279 which are about 10 apart. The pixon technique is able to determine the uxes and locations of a number of discrete sources within close proximity to each other. Fluxes and upper limits have been determined for both sources in the three standard MeV ?1 , respectively. These results are compared with other analyses of VP3. The full COMPTEL data set from 1 to 30 MeV was also separated into 19 energy intervals. For each energy interval a background set was produced from one of the sets for the standard energy ranges. Preliminary high resolution energy spectra are presented for 3C273 and 3C279 for VP3. When additional viewing periods are combined the spectral breaks characteristic of these two AGN sources should be more precisely deened.

متن کاملLong Baseline Polarimetry of 3 C 273 and 3 C 279 with the Coordinated Millimeter VLBI Array
86 GHz Very Long Baseline Polarimetry probes magnetic field structures within the cores of Active Galactic Nuclei at higher angular resolutions and a spectral octave higher than previously achievable. Observations of 3C 273 and 3C 279 taken in April 2000 with the Coordinated Millimeter VLBI Array have resulted in the first total intensity (Stokes I) and linear polarization VLBI images reported ...
متن کاملProteome analysis of Cryptosporidium parvum and C. hominis using two-dimentional electrophoresis, image analysis and tandem mass spectrometry
Until recently, Cryptosporidium was thought to be a single species genus. Molecular studies now showthat there are at least 10 valid species of this parasite. Among them, two morphologically identical species, C.hominis and C. parvum are the most pathogenic identified to date and share 97% of identical genomes.Post-genomic analyses is therefore necessary to explore further the...

The COMPTEL experiment aboard the Compton Gamma-Ray Observatory (CGRO) has observed the gamma-ray blazar 3C 279 several times between April 1991 and September 1995. This paper reports on a consistent analysis of these observations using the most recent COMPTEL data analysis tools. Detections and non-detections of 3C 279 along the CGRO-mission indicate a time-variable MeVflux. Spectral variabili...
متن کاملObject Level Strategy for Spectral Quality Assessment of High Resolution Pan-sharpen Images
Panchromatic and multi-spectral images produced by the remote sensing satellites are fused together to provide a multi-spectral image with a high spatial resolution at the same time. The spectral quality of the fused images is very important because the quality of a large number of remote sensing products depends on it. Due to the importance of the spectral quality of the fused images, its eval...
