Szekeres Swiss-Cheese model and supernova observations

Understand

We use different particular classes of axially symmetric Szekeres Swiss-cheese models for the study of the apparent dimming of the supernovae of type Ia.

• We compare the results with those obtained in the corresponding Lemaitre-Tolman Swiss-cheese models.
• Although the quantitative picture is different the qualitative results are comparable, i.e, one cannot fully explain the dimming of the supernovae using small scale ~50 Mpc inhomogeneities.
• To fit successfully the data we need structures of order of 500 Mpc size or larger.
