Emergence of smooth distance and apparent magnitude in a lumpy Universe
Obinna Umeh
The standard interpretation of observations such as the peak apparent magnitude of Type Ia supernova made from one location in a lumpy Universe is based on the idealised Friedmann-…

Consequences of using a smooth cosmic distance in a lumpy universe: I
Obinna Umeh
How do we appropriately fit a model based on an idealised Friedmann-Lema\^{}tre Robertson-Walker spacetime to observations made from a single location in a lumpy Universe? We addre…

The art of building a smooth cosmic distance ladder in a perturbed universe
Obinna Umeh
How does a smooth cosmic distance ladder emerge from observations made from a single location in a lumpy Universe? Distances to Type Ia supernovae in the Hubble flow are anchored o…
