On Open Inflation, the string theory landscape and the low CMB quadrupole
Michael Barnard, Andreas Albrecht
Cosmologists have embraced a particular ad hoc formula for the primordial power spectrum from inflation for universes with . However, the so-called ``Open Inflation'' mode…
Weak Lensing and Supernovae: Complementary Probes of Dark Energy
L. Knox, A. Albrecht, Y. S. Song
Weak lensing observations and supernova observations, combined with CMB observations, can both provide powerful constraints on dark energy properties. Considering statistical error…
Holographic Limitations of the Effective Field Theory of Inflation
Andreas Albrecht, Nemanja Kaloper, Yong-Seon Song
Holographic considerations may provide a glimpse of quantum gravity beyond what is currently accessible by other means. Here we apply holography to inflationary cosmology. We argue…
Defect models of cosmic structure in light of the new CMB data
Andreas Albrecht
Defect models of cosmic structure formation have faced a number of difficult challenges over recent years. Yet interestingly, new CMB data does not show strong evidence for seconda…
Cosmic Inflation
Andreas Albrecht
I review the current status of the theory of Cosmic Inflation. My discussion covers the motivation and implementation of the idea, as well as an analysis of recent successes and op…
Coherence and Sakharov Oscillations in the Microwave Sky
Andreas Albrecht
I discuss the origin of the ``Sakharov oscillations'' (or ``secondary Doppler peaks'') in standard angular power spectra of the Cosmic Microwave Background anisotropies calculated…
