Asta Heinesen

Asta Heinesen is a Postdoctoral Fellow at the Niels Bohr International Academy (NBIA), affiliated with the University of Copenhagen. Her research focuses on theoretical cosmology, numerical relativity, and observational cosmology, particularly in areas such as redshift drift, cosmic averaging, dark energy, cosmic expansion, and relativistic effects in the local universe. She has published extensively on cosmological tensions, inhomogeneous universe modeling, and the implications of spacetime geometry for observational data.

Her recent work includes contributions to the CosmoVerse White Paper, analyses of redshift drift using numerical relativity, and studies on the dipole and quadrupole anisotropies in the local Hubble flow. She has also explored the covariance of scalar averaging and backreaction in relativistic cosmology, and the role of structure formation in dynamical spatial curvature.

Her publications highlight a strong emphasis on model-independent cosmological inference, cosmic drift signals, and the interplay between theoretical physics and observational astrophysics. Key themes include cosmography, dark energy probes, and resolving cosmological tensions through relativistic frameworks.
