摘要：

We study the prospects of using the low-redshift and high-redshift black hole shadows as new cosmological standard rulers for measuring cosmological parameters.We show that,using the low-redshift observation of the black hole shadow of M87;,the Hubble constant can be independently determined with a precision of about 13% as H;=70±9 km s;Mpc;.The high-redshift observations of super-massive black hole shadows may accurately determine a combination of parameters H;and Ω;,and we show by a simple simulation that combining them with the type Ia supernovae observations would give precise measurements of the cosmological parameters.
