Over a decade and half ago, Banados, Silk, and West (BSW) discovered that particle traveling along geodesics can collider near the horizon of a black hole (BH) with arbitrarily high center-of-mass (CM) energy if one of the particles has its angular momentum tuned to a critical value, opening the prospect that BHS may act as act as high-energy particle colliders (HEPCs). It has been speculated that rapidly rotating black holes (BHs) with accretion disks---either prograde or retrograde---are natural astrophysical HEPCs because BSW-type collisions can occur between particles falling in from infinity and particles in the disk. In this talk, I present work to understand the naturalness and observability of these high-energy collisions around (near-)extremal BHs. I will highlight 1) the landscape of conditions under which these BSW-type collisions occur, 2) the most viable accretion disk configuration conducive to BHs acting as astrophysical HEPCs via BSW-type collisions when considering scattering, and 3) the observability as measure by the escape probability and expected energy of emission born of a BSW-type collision.
