We study the uniqueness and robustness of acoustic signatures in the cosmic microwave background by allowing for the possibility that they are generated by some as yet unknown source of gravitational perturbations. The acoustic pattern of peak locations and relative heights predicted by the standard inflationary cold dark matter model is essentially unique, and its confirrmation would have deep implications for the causal structure of the early universe. A generic pattern for isocurvature…

CMBR anisotropy measurements probe directly some detailed physics of the early universe--the decoupling of matter and radiation at a temperature of about 4,000 K and a time about 300,000 years after the bang.
Cosmic Microwave Background Acoustic Peak Locations
The Planck collaboration has measured the temperature and polarization of the cosmic microwave background well enough to determine the locations of eight peaks in the temperature (TT) power spectrum,
DISSERTAÇÃO Non Gaussian Fluctuations in the Cosmic Microwave Background Radiation
The temperature fluctuations of the Cosmic Microwave Background (CMB) validates the ΛCDM with incredible precision and has opened a door to the physics of the early universe. These perturbations are
Baryonic signatures in Large-Scale Structure
We investigate the consequences of a non-negligible baryon fraction for models of structure formation in cold dark matter dominated cosmologies, emphasizing in particular the existence of
Acoustic Oscillations in the Early Universe and Today
Comparisons of the CMB detections with the corresponding acoustic oscillations in the matter-density power spectrum provide further support for the standard Hot Big Bang model of the universe.
Cosmic microwave background and first molecules in the early universe
Besides the Hubble expansion of the universe, the main evidence in favor of the big-bang theory was the discovery, by Penzias and Wilson, of the cosmic microwave background (hereafter CMB) radiation.
On the Robustness of the Acoustic Scale in the Low-Redshift Clustering of Matter
We discuss the effects of nonlinear structure formation on the signature of acoustic oscillations in the late-time galaxy distribution. We argue that the dominant nonlinear effect is the differential
Cosmic microwave background constraints on the strong equivalence principle
We study the effect of a violation of the strong equivalence principle (SEP) on the cosmic microwave background (CMB). Such a violation would modify the weight of baryons in the primordial
The cosmic microwave background: observing directly the early universe
The Cosmic Microwave Background (CMB) is a relict of the early universe. Its perfect 2.725K blackbody spectrum demonstrates that the universe underwent a hot, ionized early phase; its anisotropy
Dependence of the cosmic microwave background lensing power spectrum on the matter density
The anisotropies in the cosmic microwave background (CMB) provide our best laboratory for testing models of the formation and evolution of large-scale structure. The rich features in the cosmic
