I appreciate your help but I could you add more steps to in the integration process and how you use the erf.

comment Integrating the Gaussian kernel with absolute value
I understand how to split the integral, but if is make $z=-y$ in the second integral I get $\int_0^{\infty}ze^{-(\xi+z)^2/4t}$ which is different to the first integral

I cannot see how the second integral is the same as the first
