Looking for Cosmic Strings in New Observational Windows Speaker(s): Robert Brandenberger
Abstract: Cosmic strings are predicted to arise in both inflationary
and non-inflationary cosmological models. The signatures of
such strings will stand out particularly well at higher
redshifts. I will discuss how to look for these signatures
in CMB redshift and polarization maps and in 21cm redshift

Holography in String Gas Cosmology Speaker(s): Robert Brandenberger
Abstract: I will review the string gas scenario of structure formation, stressing the role which holography plays. I will also discuss another way of obtaining a scale-invariant spectrum of cosmological perturbations (with specific signatures in the bispectrum) which may be realizable in scenarios based on th... read more

Cosmology of the Lee-Wick Model Speaker(s): Robert Brandenberger
Abstract: The Lee-Wick model has recently been put forwards as an alternative to supersymmetry for solving the hierarchy problem of particle physics. I will show that, modulo important consistency questions, coupling the Lee-Wick model to cosmology leads to a bouncing universe cosmology with a scale-invariant... read more

Probing string theory through cosmological observations? Speaker(s): Robert Brandenberger
Abstract: If string theory is the correct theory which unifies gravity with the other forces of nature at a quantum level, it should determine the evolution of the earliest stages of the universe. I will discuss how stringy signatures of this early phase may be visible in current cosmological observations.
