| 英文摘要 | We investigate analytically the apparent shadows cast by Kerr-Newman black hole with surrounding perfect fluid matter in Rastall gravity theory. With the help of the Hamilton-Jacobi equation and Carter constant separable method, we derive the null geodesics of the black hole space-time and calculate the numerical results of the horizon structures. The results reveal that three horizons (Cauchy horizon r -, event horizon r + and cosmological horizon r q ) occur in the space-time, and the horizon structure could degenerate while the Rastall parameter k lambda arrives the critical value. By fixing the value of equation state parameter omega similar to of surrounding substance for both cases of dark matter ( omega similar to=-1/3 ) and dark energy ( omega similar to=-2/3 ), we study the effects of the perfect fluid matter intensity N s , the Rastall parameter k lambda, the black hole spin a and the black hole charge Q on black hole shadows in detail. Furthermore, the effective potentials for black hole space-time and the energy emission rate of the black hole are also conducted and discussed. |
