[ 1 ] - جستجو در تصاویر عمیق GaBoDs برای یافتن خوشه‌های کهکشانی به روش همگرایی ضعیف گرانشی

The aim of the present work is detection of galaxy clusters based on weak gravitational lensing method. We apply mass aperture statistics method to 0.32 square degrees data obtained with the WFI@MPG/ESO 2.2 m telescope and detect mass peaks based on their mass not the luminosity. So by the application of proper filter function, shear profile and mass map are produced. Finally mass peaks with hi...
