We explore 1/16-BPS objects of type IIB string theory in AdS5 ? S5. First, we consider supersymmetric AdS5 black holes, which should be 1/16-BPS and have a characteristic that not all physical charges are independent. We point out that the Bekenstein-Hawking entropy of these black holes admits a remarkably simple expression in terms of (dependent) physical charges, which suggests its microscopic origin via certain Cardy or Hardy-Ramanujan formula. We also note that there is an upper bound for the angular momenta given by the electric charges. Second, we construct a class of 1/16-BPS giant graviton solutions in AdS5 ? S5 and explore their properties. The solutions are given by the intersections of AdS5 ? S5 and complex 3 dimensional holomorphic hyperspaces in 1+5, the latter being the zero loci of three holomorphic functions which are homogeneous with suitable weights on coordinates. We investigate examples of giant gravitons, including their degenerations to tensionless strings.
