Explicit log Fano structures on blow-ups of projective spaces

In this paper we determine which blow-ups $X$ of $\mathbb{P}^n$ at general points are log Fano, that is, when there exists an effective $\mathbb{Q}$-divisor $\Delta$ such that $-(K_X+\Delta)$ is ample and the pair $(X,\Delta)$ is klt. For these blow-ups, we produce explicit boundary divisors $\Delta$ making $X$ log Fano.
