Study On The Effect Of High - Gravitational Lens In Abell 1835

Gravitational lensing is one of the predictions by General Relativity. Light deflection in gravitational fields can be calculated through geodesic curves. There are three kinds of gravitational lensing named strong gravitational lensing, weak gravitational lensing and micro gravitational lensing respectively. They are powerful tools for studying cosmology and astrophysics in different astronomy sizes. Sometimes people do research by combining parts or all of them.Abell 1835 comes from Abell catalogue, its redshift z is 0.253 as a nearby galaxy cluster. As a typical lensing galaxy cluster, Abell 1835 has much references about gravitational lensing research. In recent years, some researches show that existing a strong cooling core source in the galaxy cluster center. Its cooling time is less than the age of universe at the cluster’s redshift. People have discovered the most distant galaxy which is named Galaxy Abell 1835-IR1916 by means of strong gravitational lensing’s amplification effect. This galaxy can help people to learn early universe. X-ray telescopes Chandra and Suzaku both have observations of Abell 1835. After then Morandi and Okabe have used X-ray data to fitting the mass profile respectively.This paper has used the method which is based on strong gravitational lensing to fit the mass distribution of Abell 1835. The image data used in the paper was chosen from HST database including optics data(detector:WFPC2) with filters: F702 W. In this paper, the mass density distribution profile is PIEMD model, fitting optimization method is Bayesian method which is based on Bayesian probability.Because of the complexity of Abell 1835 lensing model, this paper fitted the mass distribution with a step-by-step way. Start with the simplest system state, then put more mass and gravitational potentials in the lensing system according to the previous results. In the end of paper, the different results in other papers have be discussed.
