Conformal gravity holography in four dimensions
  We formulate four-dimensional conformal gravity with (Anti-)de Sitter
boundary conditions that are weaker than Starobinsky boundary conditions,
allowing for an asymptotically subleading Rindler term concurrent with a recent
model for gravity at large distances. We prove the consistency of the
variational principle and derive the holographic response functions. One of
them is the conformal gravity version of the Brown-York stress tensor, the
other is a `partially massless response'. The on-shell action and response
functions are finite and do not require holographic renormalization. Finally,
we discuss phenomenologically interesting examples, including the most general
spherically symmetric solutions and rotating black hole solutions with
partially massless hair.
