Constraints on Decaying Dark Matter
Annika H. G. Peter, Christopher E. Moody, Andrew J. Benson +1
We explore a dark-matter model in which there are two dark-matter species nearly degenerate in mass, with epsilon = Delta M/M << 1. The heavier particle undergoes two-body decay wi…
The Odd-Parity CMB Bispectrum
Marc Kamionkowski, Tarun Souradeep
Measurement of the cosmic microwave background (CMB) bispectrum, or three-point correlation function, has now become one of the principle efforts in early-Universe cosmology. Here…
The CMB Bispectrum, Trispectrum, non-Gaussianity, and the Cramer-Rao Bound
Marc Kamionkowski, Tristan L. Smith, Alan Heavens
Minimum-variance estimators for the parameter fnl that quantifies local-model non-Gaussianity can be constructed from the cosmic microwave background (CMB) bispectrum (three-point…
