PIRSA:07090047  ( MP4 Medium Res , MP3 , PDF ) Which Format?
The Contributions (and Limitations) of Type Ia Supernovae to Cosmology
Speaker(s): Bruno Leibundgut
Abstract: The cosmological power of Type Ia Supernovae depends on their ability to determine distances. The astrophysical limitations, like reddening, local velocity inhomogeneities and intrinsic variations, are a severe impediment for the cosmological applications of these cosmic explosions. Overcoming these... read more

Primordial black holes in the dark ages
Speaker(s): Katherine Mack
Abstract: We investigate the effect of evaporating primordial black holes on the ionization history of the universe, with emphasis on limits derivable from the CMB and future 21-cm observations of high-redshift neutral hydrogen.

PIRSA:07090029  ( MP4 Medium Res , MP3 , PDF ) Which Format?
K-Essence, superluminal propagation, causality and emergent geometry
Speaker(s): Alex Vikman
Abstract: The k-essence theories admit the superluminal propagation of the perturbations on classical nontrivial backgrounds. In this talk I will review our arguments from arXiv:0708.0561v1 and show that in spite of the superluminal propagation the causal paradoxes do not arise in these theories and in this r... read more
