| Summary:
One of the key issues in holography is going beyond $mathrm{AdS}$ and
defining quantum gravity in spacetimes with a null boundary. Recent examples of
this type involve linear dilaton asymptotics and are related to the $T
overline{T}$ deformation. We present a holographic correspondence derived from
string theory, which is an example of a kind of celestial holography. The
holographic definition is a spacetime non-commutative open string theory
supported on D1-D5 branes together with fundamental strings. The gravity
solutions interpolate between $mathrm{AdS}_3$ metrics and six-dimensional
metrics. Radiation can escape to null infinity, which makes both the encoding
of quantum information in the boundary and the dynamics of black holes quite
different from $mathrm{AdS}$ spacetimes.
