We present the results of our optical identification of the X-ray source IGR J16547-1916 detected by the INTEGRAL observatory during a deep all-sky survey. Analysis of the spectroscopic data from the ...
Can past gamma-ray bursts explain both INTEGRAL and PAMELA/Fermi anomalies simultaneously?
Gamma ray bursts gamma-ray bursts

2010/3/9
Gamma-ray bursts (GRB) have been invoked to explain both the 511 keV emission from the galactic bulge and the high-energy positron excess inferred from the PAMELA and Fermi data. While independent exp...
