11:00 → 12:00 Islands in Kerr-de Sitter spacetime and flat-space cosmologies

Recently the island conjecture has gained a lot of attention in order to address the information paradox problem and a considerable amount of work has been done in numerous cases. We have studied two different setups in this context, flat space cosmologies and Kerr-de Sitter spacetime in three dimensions. It is argued that by coupling an auxiliary flat bath system at the timelike singularities of these spacetimes one can reconstruct the Page curve and namely solve the information paradox. Furthermore the relationship between the two island regions in these cases has been discussed.
