abstract
We study cosmological solutions of the IKKT model with $k=-1$ FLWR geometry, taking into account one-loop corrections. A previously discussed covariant quantum spacetime is found to be stabilized through one-loop effects at early times, without adding a mass term to the model. At late times, this background is modified and approaches a solution of the classical model where $a(t) \sim const$, but the dilaton decreases in time. This suggests that a more complete treatment of the system is required in the late-time regime.

Minimal covariant quantum space-time
The minimal covariant quantum space-time M^{1,3}_0 is shown to be a quantized twistor space, an S2 bundle over a k=-1 FLRW space-time, with localized quasi-coherent states.

Observational Constraints on Kazakov-Solodukhin Quantum-Deformed Black Holes from M87$^*$ and Sgr A$^*$ Shadows
EHT shadow sizes of M87* and Sgr A* constrain the Kazakov-Solodukhin deformation parameter η to O(1) ranges while the metric remains asymptotically Schwarzschild.
