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.

Early Star Formation in Molecular Clouds: A comprehensive Atlas with ALMA and SOFIA


Highmass stars are cosmic engines known to dominate the energetics in the Milky Way and other galaxies. However, they are very rare and their formation is still not well understood. High-mass, cold, dense clouds are the nurseries of high-mass stars. Mainly I will be discussing two projects that I am currently leading. One part of my talk will focus on a large systematic search for Cold Cores with ALMA (CoCoA). With a survey machine like ALMA, CoCoA aims to reveal the truly high-mass starless cores if they exist. SIMPLIFI is a SOFIA HAWC+ Legacy pilot program that is carrying out the first high resolution large-scale study of the magnetic po ...
