Precision Cosmology and the Density of Baryons in the Universe
M. Kaplinghat, M. S. Turner
Big-bang Nucleosynthesis (BBN) and Cosmic Microwave Background (CMB) anisotropy measurements give independent, accurate measurements of the baryon density and can test the framewor…
Annihilating Cold Dark Matter
M. Kaplinghat, L. Knox, M. S. Turner
Structure formation with cold dark matter (CDM) predicts halos with a central density cusp, which are observationally disfavored. If CDM particles have an annihilation cross sectio…
Gravitational Microlensing and the Galactic Halo
Evalyn I. Gates, Geza Gyuk, Michael S. Turner
By means of extensive galactic modeling we study the implications of the more than eighty microlensing events that have now been observed for the composition of the dark halo of th…
Microlensing and Halo Cold Dark Matter
Evalyn I. Gates, Geza Gyuk, Michael S. Turner
We discuss the implications of the more than 50 microlensing events seen by the EROS, MACHO, and OGLE collaborations for the composition of the halo of our galaxy. The event rates…
Relaxing the Big-bang Bound to the Baryon Density
G. Gyuk, M. S. Turner
In the standard picture of big-bang nucleosynthesis the yields of D, He, He, and Li only agree with their inferred primordial abundances if the fraction of critical den…
Is a Massive Tau Neutrino Just What Cold Dark Matter Needs?
Scott Dodelson, Geza Gyuk, Michael S. Turner
The cold dark matter (CDM) scenario for structure formation in the Universe is very attractive and has many successes; however, when its spectrum of density perturbations is normal…
