In this talk, I would like to start with the introduction to the exact accelerating string solution of a heavy quark-antiquark pair in $AdS_5$ space.
On the accelerating string, there is a particular scale which separates the radiation and the heavy quark. This scale is explicitly shown to be an event horizon in the proper frame of the heavy quark. Furthermore, I will describe a new correspondence, which relates the horizon in $AdS_5$ space on the gravity theory side to the Unruh temperature in Minkowski space on the field theory side of the AdS/CFT correspondence. $p_{\perp}$-broadening and $p_{L}$-broadening of the heavy quark due to radiation are computed using the AdS/CFT correspondence. In the end, using AdS/CFT correspondence and the accelerating string solution, heavy quark energy loss in finite extent plasma is discussed.
