On Breaking Cosmic Degeneracy
It has been argued that the power spectrum of the anisotropies in the Cosmic Microwave Background (CMB) may be effectively degenerate, namely that the observable spectrum does not determine a unique set of cosmological parameters. We describe the physical origin of this degeneracy and show that at small angular scales it is broken by gravitational lensing: effectively degenerate spectra become ...
متن کاملDegeneracy Breaking, Modal Symmetry and MEMS Biosensors
This work is concerned with degenerate modes of vibration in problems involving rotational symmetries of finite order. In the case of infinite order symmetry of the material and the geometry, two degenerate mode pairs exist for each natural number, corresponding to the cyclic periodicity of the solution. Degenerate sensors have been developed in MEMS over the past 20 years that exploit weak cou...
متن کاملBreaking cosmic strings without monopoles.
It is shown that topologically stable cosmic strings can, in fact, appear to end or to break, even in theories without monopoles. This can occur whenever the spatial topology of the universe is nontrivial. For the case of Abelian-Higgs strings, we describe the gauge and scalar field configurations necessary for a string to end on a black hole. We give a lower bound for the rate at which a cosmi...
متن کاملBreaking the color-reddening degeneracy in type Ia supernovae
A new method to study the intrinsic color and luminosity of type Ia supernovae (SNe Ia) is presented. A metric space built using principal component analysis (PCA) on spectral series SNe Ia between −12.5 and +17.5 days from B maximum is used as a set of predictors. This metric space is built to be insensitive to reddening. Hence, it does not predict the part of color excess due to dust-extincti...
متن کاملBreaking the mass / anisotropy degeneracy in the Coma cluster
We provide the first direct lifting of the mass/anisotropy degeneracy for a cluster of galaxies, by jointly fitting the line of sight velocity dispersion and kurtosis profiles of the Coma cluster, assuming an NFW tracer density profile, a generalized-NFW dark matter profile and a constant anisotropy profile. We find that the orbits in Coma must be quasi-isotropic, and find a mass consistent wit...
