We calculate durations and spectral parameters for 218 Swift bursts detected by the BAT instrument between and including GRBs 041220 and 070509, including 77 events with measured redshifts. Incorporating prior knowledge into the spectral fits, we are able to measure the characteristic νFν spectral peak energy Epk,obs and the isotropic equivalent energy Eiso (1–10 4 keV) for all events. This com...

The study of human interactions and the modeling of social structures often require large-scale computational experiments involving complex models and substantial computational resources. The formulation of such models and computations can be taxing for researchers. We introduce the Swift parallel programming system and the SwiftScript scripting language, which together enable the rapid specifi...

— The appearance of a new programming language gives the necessity to contrast its contribution with the existing programming languages to evaluate the novelties and improvements that the new programming language offers for developers. These kind of studies can show us the efficiency, improvements and useful or uselessness of the new programming languages. Also these studies can show us the goo...

the date of receipt and acceptance should be inserted later Abstract. We report the results of analyzing Swift, RossiXTE, and INTEGRAL data of Swift J1922.7-1716, a likely transient X-ray source discovered by Swift/BAT. Both the fast variability measured by the RXTE/PCA and the combined Swift/XRT, RXTE/PCA, and INTEGRAL/ISGRI (0.5–100 keV) energy spectrum suggest that the system is a neutron-st...
