The 19-year-old pianist and composer performed his most recent work all over Europe, Asia, and North America last year, winning prestigious awards in both London and Tokyo for his achievement at such a young age, and he hopes to continue composing now that he has returned to Chicago.

正确句子中最后的that he has returned to Chicago, 到底是是he hopes...句子中做什么成分呢？

now that 是一个idiom，可做连词的属性，表示“既然”。
意思是他希望继续自己的作曲，既然已经回到芝加哥了。
